* h5cc: Fix location of settings and pkgconfig files
In h5cc and other compiler wrappers, drop hardcoded 'lib' as the dir for
libhdf5.settings and pkgconfig scripts and use cmake computed values for
HDF5_INSTALL_LIB_DIR. This fixes issues on systems where the libdir is
'lib64' for instance, as on 64-bit Linux OSes, and 'lib' in the
wrappers point to incorrect locations of the settings and pkgconfig
files.
* h5cc: Drop -show from output when calling command.
When calling `h5cc -show FOO`, the output should not repeat the '-show'
argument itself. This commit fixes the '-show' command invoked from a
cmake built h5cc to be consistent with an (previously) autotools built
one.
Added infrastructure support for multithreaded concurrency by adding an optional way to switch to using a non-recursive R/W lock for the global API lock. This is enabled with a new 'concurrency' configuration flag for the autotools & CMake builds, which is disabled by default.
When the 'concurrency' build option is chosen, the global API lock will use the R/W lock and all API calls currently will acquire a write lock, ensuring exclusive access by one thread. Over time, the API routines that are converted to support multithreaded concurrency will switch to acquiring a read lock instead.
Reentering the library from application callbacks is managed by the 'disable locking for this thread' (DLFTT) threadsafety protocol. This is internally handled within the H5_API_LOCK / H5_API_UNLOCK macros in H5private.h (as before), which invoke the 'dlftt' routines in H5TSint.c.
To support this change, the threadsafety configuration macros for the library have been updated:
- --enable-threadsafe now defines the H5_HAVE_THREADSAFE macro
- --enable-concurrency defines the H5_HAVE_CONCURRENCY macro
The new H5_HAVE_THREADSAFE_API macro is set if either H5_HAVE_THREADSAFE or H5_HAVE_CONCURRENCY is enabled.
New Github actions are added to include the concurrency configuration in the CI for the develop branch.
To support the new non-recursive R/W locking for API routines, some other changes are necessary:
Added macro wrappers around all callback invocations that could call an
application function, and therefore re-enter the library:
H5_BEFORE_USER_CB* / H5_AFTER_USER_CB*
Added H5_user_cb_prepare / H5_user_cb_restore routines that save the
state of the library when callback leaves the library. Includes error
stack and threadsafe reentry state currently.
There's also some small cleanups to various places in the library:
Moved the H5E_mpi_error_str / H5E_mpi_error_str_len globals to be local for
pushing MPI errors, so that multiple threads can't interfere with each
other.
Added H5TS_rwlock_trywrlock() routine to R/W lock interface.
Emulate R/W locks on MacOS because its implementation of
pthread_rwlock_wrlock() does not conform to the POSIX standard.
Don't acquire the global API lock in H5close, since it's acquired in H5_term_library, which is necessary because H5_term_library is invoked via other code paths that don't hold the global API lock.
Don't call H5Eget_auto2 API routine within H5_term_library.
Switched 'return NULL' in H5allocate_memory to HGOTO_DONE(NULL).
Switched H5Pget_file_space_strategy / H5Pset_file_space_strategy to use
internal routines instead of API routines.
Switched H5Oopen_by_addr & H5Ovisit1 to use internal routines instead of
API routines.
Fixed a few places in src/H5Odeprec.c where a major
error ID was passed as a minor ID.
* Implement support for complex number datatypes
Adds the new datatype class H5T_COMPLEX
Adds the new API function H5Tcomplex_create which creates a complex
number datatype from an ID of a base floating-point datatype
Adds the new feature check macros H5_HAVE_COMPLEX_NUMBERS and
H5_HAVE_C99_COMPLEX_NUMBERS
Adds the new datatype size macros H5_SIZEOF_FLOAT_COMPLEX,
H5_SIZEOF_DOUBLE_COMPLEX and H5_SIZEOF_LONG_DOUBLE_COMPLEX
Adds the new datatype ID macros H5T_NATIVE_FLOAT_COMPLEX,
H5T_NATIVE_DOUBLE_COMPLEX, H5T_NATIVE_LDOUBLE_COMPLEX,
H5T_CPLX_IEEE_F16LE, H5T_CPLX_IEEE_F16BE,
H5T_CPLX_IEEE_F32LE, H5T_CPLX_IEEE_F32BE,
H5T_CPLX_IEEE_F64LE and H5T_CPLX_IEEE_F64BE
Adds hard and soft datatype conversion paths between complex number
datatypes and all the integer and floating-point datatypes, as well as
between other complex number datatypes
Adds a special conversion path between complex number datatypes and
array or compound datatypes where the in-memory layout of data is the
same between the datatypes and data can be converted directly
Adds support for complex number datatypes to the h5dump, h5ls and
h5diff/ph5diff tools. Allows h5dump '-m' option to change floating-point
printing format for float complex and double complex datatypes, as well
as long double complex if it has the same size as double complex
Adds minimal support to the h5watch and h5import tools
Adds support for the predefined complex number datatypes and
H5Tcomplex_create function to the Java wrappers. Also adds initial,
untested support to the JNI for future use with HDFView
Adds support for just the H5T_COMPLEX datatype class to the Fortran
wrappers
Adds support for the predefined complex number datatypes and
H5Tcomplex_create function to the high level library H5LT interface
for use with the H5LTtext_to_dtype and H5LTdtype_to_text functions
Changes some usages of "complex" in the library since it conflicts with
the "complex" keyword from the complex.h header. Also changes various
usages of the word "complex" throughout the library to distinguish
compound datatypes from complex datatypes.

Solaris Studio hasn't been updated in almost a decade and the last
version (12.4, circa 2015) doesn't seem to fully support C11.
This PR removes some work-arounds for things like __attribute__()
support.
The CMake compiler checks skip checking for things like __attribute__()
on Windows. Now that Visual Studio can use clang, we should be checking
for this, even on non-MinGW Windows.
This is where most people will expect to find license information. The
COPYING_LBNL_HDF5 file has also been renamed to LICENSE_LBNL_HDF5.
The licenses are unchanged.
Ignores some of the older Autotools platform files, since the Autotools
will be dropped in the next major release (and we don't have
compilers on which to test, anyway).
Also drops support for the old, non-compliant MSVC
preprocessor.
* Cleanup threads package checks
* Check first if package was found
