Snprintf2 (#1399)
* Replaced many uses of sprintf with safer snprintf

Many very straightforward, but in a few cases added a length parameter to some private functions, because buffer length was otherwise unknowable.

* Removed unnecessary use of static on small buffers

This improves thread safety.

* Committing clang-format changes

ca3659a014 HD prefix updates in src/ and test/
Adds missing HD prefixes to API calls in src and test.

Adds some extra processing to bin/checkposix to keep the noise
levels down when running the script (not comprehensive).

f60170dac7 [svn-r28761] Description:
Clean up many mismatches between malloc/free and H5MM_malloc/H5MM_xfree
in the library and tests (and use of H5free_memory and H5Dvlen_reclaim).  Also
make H5Ocopy use a private version of H5Lexists, which doesn't internally
throw (and suppress) errors when an object (or the path to it) isn't found in
the destination.

Tested on:
    MacOSX/64 10.11.2 (amazon) w/serial & parallel

9431c7a97e [svn-r20536] Description:
Clean up various warnings & code formatting issues.

	Bring changes from Coverity branch to trunk:

r20085:
Purpose: Fix coverity issue 793

Description: Modified H5S_hyper_project_simple_higher() to free the entire span
list in new_space on failure.


r20091:
This is a fix for coverity bug #1683.
Changed the two printfs to use %lu (unsigned long) for printing "dset_size".


r20162:
Purpose: Fix coverity issue 785

Description: Modified H5T_enum_nameof() to free "name" on failure if it was
allocated.  Also clarified some code in H5S_hyper_rebuild_helper().


r20189:
Addressed coverity defect 783.

H5SL_new_node() in H5SL.c was failing to free space allocated in its
first alloc if the second alloc failed.  Added a call to H5FL_FREE
to address this issue.

This is purely to keep coverity happy -- if this code is ever triggered,
we have much larger problems.

Note that this fix will trigger an unused return value complaint
from coverity next week.


r20190:
Fixed Coverity issues 1561 1565 and 1678 (UNUSED_VALUES) by moving checks of return values to after the function call.


r20191:
Fixed coverity issues 643 644 and 1678 (CHECKED_RETURN).


r20232:
Addressed coverity issues 923-925.  Replaced calls to sprintf with calls
to HDsnprintf.


r20233:
Fix coverity issue 662.  Don't try to sort 0 attributes in H5Aint.c.


r20234:
Fix coverity issue 664.  Check for NULL before dereferencing in H5Gdeprec.c.


r20271:
Purpose: Fix coverity issue 784

Description: Modified H5_debug_mask() to keep a list of files opened for use as
a debugging output stream, and modified H5_term_library to close these files on
exit.


r20272:
addressed coverity issues 838 & 955.  Issue was use of strcpy() -- existing
code was safe, but modified to use strncpy() to keep coverity happy.


r20273:
Addresed coverity issues 1388 and 1389.
Initialized sel_iter->type to NULL in H5S_select_iter_init.


r20275:
Purpose: Fix valgrind issue in mf.c

Description: Fixed bug (incomplete if statement) in test_mf_fs_alloc_free() so
the retrieved node gets freed.

7a92820e35 [svn-r15183] Purpose: _WIN32 macro cleanup
Description:
As part of our Windows cleanup, we try to remove windows-specific tweaks in the source code.  There are many instances where Windows code is introduces via ifdef's.  We re-evaluate whether they are still required, and found that many of them are not.  Others we change to "feature"-specific code, rather than Windows-specific.

87a41d4286 [svn-r13766] In Visual Studio 2005 for 64-bit, _WIN32 is defined, but not WIN32, so I've standardized all #ifdef's to use _WIN32. This should not affect any other platform.
Tested:

4eed634bcf [svn-r13542] Added a detection for zero-length VL data in H5T_conv_vlen to handle the case properly. This fix
was discovered by the user while Bug #717 was being fixed.  Modefied the test, too.

ed7d456e51 [svn-r13253] Updated all C and C++ style source code files with the THG copyright notice.
Tested platform:
Kagiso only since it is only a comment block change.  If it works in one
machine, it should work in all, I hope.  Still need to check the parallel
build on copper.

00edaf52c5 [svn-r8053] Purpose:
Bug fix

Description:
    Correct two problems with variable-length datatypes in datasets:
        - When overwriting an entire dataset, writing the fill value to the
            file would be skipped, causing problems for VL datatypes when
            objects in the file had been unlinked (and thus the space in the
            file was not all zeros)
        - When an application has set a fill-value for a dataset and the
            dataset's datatype contained a VL datatype, the library was filling
            space on disk with the memory form of the VL information, instead
            of the disk form.

e1792ebb22 [svn-r7842] Purpose:
Bug fix

Description:
    Variable length strings and sequences with NULL pointers were not handled
by library, causing problems access the data.  This also affected fill values
for variable-length datatypes.

Solution:
    Address the issues in the library by detecting NULL sequences/strings
and avoid trying to convert them.

    Patched up dumper to display NULL sequences/strings.

9a433b99a5 [svn-r6252] Purpose:
Lots of performance improvements & a couple new internal API interfaces.

Description:
    Performance Improvements:
        - Cached file offset & length sizes in shared file struct, to avoid
            constantly looking them up in the FCPL.
        - Generic property improvements:
            - Added "revision" number to generic property classes to speed
                up comparisons.
            - Changed method of storing properties from using a hash-table
                to the TBBT routines in the library.
            - Share the propery names between classes and the lists derived
                from them.
            - Removed redundant 'def_value' buffer from each property.
            - Switching code to use a "copy on write" strategy for
                properties in each list, where the properties in each list
                are shared with the properties in the class, until a
                property's value is changed in a list.
        - Fixed error in layout code which was allocating too many buffers.
        - Redefined public macros of the form (H5open()/H5check, <variable>)
            internally to only be (<variable>), avoiding innumerable useless
            calls to H5open() and H5check_version().
        - Reuse already zeroed buffers in H5F_contig_fill instead of
            constantly re-zeroing them.
        - Don't write fill values if writing entire dataset.
        - Use gettimeofday() system call instead of time() system when
            checking the modification time of a dataset.
        - Added reference counted string API and use it for tracking the
            names of objects opening in a file (for the ID->name code).
        - Removed redundant H5P_get() calls in B-tree routines.
        - Redefine H5T datatype macros internally to the library, to avoid
            calling H5check redundantly.
        - Keep dataspace information for dataset locally instead of reading
            from disk each time.  Added new module to track open objects
            in a file, to allow this (which will be useful eventually for
            some FPH5 metadata caching issues).
        - Remove H5AC_find macro which was inlining metadata cache lookups,
            and call function instead.
        - Remove redundant memset() calls from H5G_namei() routine.
        - Remove redundant checking of object type when locating objects
            in metadata cache and rely on the address only.
        - Create default dataset object to use when default dataset creation
            property list is used to create datasets, bypassing querying
            for all the property list values.
        - Use default I/O vector size when performing raw data with the
            default dataset transfer property list, instead of querying for
            I/O vector size.
        - Remove H5P_DEFAULT internally to the library, replacing it with
            more specific default property list based on the type of
            property list needed.
        - Remove redundant memset() calls in object header message (H5O*)
            routines.
        - Remove redunant memset() calls in data I/O routines.
        - Split free-list allocation routines into malloc() and calloc()-
            like routines, instead of one combined routine.
        - Remove lots of indirection in H5O*() routines.
        - Simplify metadata cache entry comparison routine (used when
            flushing entire cache out).
        - Only enable metadata cache statistics when H5AC_DEBUG is turned
            on, instead of always tracking them.
        - Simplify address comparison macro (H5F_addr_eq).
        - Remove redundant metadata cache entry protections during dataset
            creation by protecting the object header once and making all
            the modifications necessary for the dataset creation before
            unprotecting it.
        - Reduce # of "number of element in extent" computations performed
            by computing and storing the value during dataspace creation.
        - Simplify checking for group location's file information, when file
            has not been involving in file-mounting operations.
        - Use binary encoding for modification time, instead of ASCII.
        - Hoist H5HL_peek calls (to get information in a local heap)
            out of loops in many group routine.
        - Use static variable for iterators of selections, instead of
            dynamically allocation them each time.
        - Lookup & insert new entries in one step, avoiding traversing
            group's B-tree twice.
        - Fixed memory leak in H5Gget_objname_idx() routine (tangential to
            performance improvements, but fixed along the way).
        - Use free-list for reference counted strings.
        - Don't bother copying object names into cached group entries,
            since they are re-created when an object is opened.

        The benchmark I used to measure these results created several thousand
        small (2K) datasets in a file and wrote out the data for them.  This is
        Elena's "regular.c" benchmark.

        These changes resulted in approximately ~4.3x speedup of the
        development branch when compared to the previous code in the
        development branch and ~1.4x speedup compared to the release
        branch.

        Additionally, these changes reduce the total memory used (code and
        data) by the development branch by ~800KB, bringing the development
        branch back into the same ballpark as the release branch.

        I'll send out a more detailed description of the benchmark results
        as a followup note.

    New internal API routines:
        Added "reference counted strings" API for tracking strings that get
            used by multiple owners without duplicating the strings.
        Added "ternary search tree" API for text->object mappings.
