in the docs directory.
1. Add a new internal document -- testserver.dox -- to describe
how to set up and maintain the dap test server.
2. It moves the internal documentation (internal.dox, indexing.dox,
and testserver.dox) to later in the documentation table of contents.
3. Cleanup the formatting of the internal documents.
4. Cleanup some minor doxygen issues in other files.

Expand the NC_INMEMORY capabilities to support writing and accessing
the final modified memory.
Three new functions have been added:
nc_open_memio, nc_create_mem, and nc_close_memio.
The following new capabilities were added.
1. nc_open_memio() allows the NC_WRITE mode flag
so a chunk of memory can be passed in and be modified
2. nc_create_mem() allows the NC_INMEMORY flag to be set
to cause the created file to be kept in memory.
3. nc_close_mem() allows the final in-memory contents to be
retrieved at the time the file is closed.
4. A special flag, NC_MEMIO_LOCK, is provided to ensure that
the provided memory will not be freed or reallocated.
Note the following.
1. If nc_open_memio() is called with NC_WRITE, and NC_MEMIO_LOCK is not set,
then the netcdf-c library will take control of the incoming memory.
This means that the original memory block should not be freed
but the block returned by nc_close_mem() must be freed.
2. If nc_open_memio() is called with NC_WRITE, and NC_MEMIO_LOCK is set,
then modifications to the original memory may fail if the space available
is insufficient.
Documentation is provided in the file docs/inmemory.md.
A test case is provided: nc_test/tst_inmemory.c driven by
nc_test/run_inmemory.sh
WARNING: changes were made to the dispatch table for
the close entry. From int (*close)(int) to int (*close)(int,void*).
Primary change is to cleanup code and remove duplicated code.
1. Unify the rc file reading into libdispatch/drc.c. Eventually extend
if we need rc file for netcdf itself as opposed to the dap code.
2. Unify the extraction from the rc file of DAP authorization info.
3. Misc. other small unifications: make temp file, read file.
4. Avoid use of libcurl when reading file:// because
there is some kind of problem with the Visual Studio version.
Might be related to the winpath problem.
In any case, do direct read instead.
5. Add new error code NC_ERCFILE for errors in reading RC file.
6. Complete documentation cleanup as indicated in this comment
https://github.com/Unidata/netcdf-c/pull/472#issuecomment-325926426
7. Convert some occurrences of #ifdef _WIN32 to #ifdef _MSC_VER
generates garbage. This in turn interferes with using .netrc
because the garbage user+pwd can will override the
.netrc. Note that this may work ok sometimes
if the garbage happens to start with a nul character.
2. It turns out that the user:pwd combination needs to support
character escaping. One reason is the user may contain an '@' character.
The other is that modern password rules make it not unlikely that
the password will contain characters that interfere with url parsing.
So, the rule I have implemented is that all occurrences of the user:pwd
format must escape any dodgy characters. The escape format is URL escaping
of the form %XX. This applies both to user:pwd
embedded in a URL as well as the use of HTTP.CREDENTIALS.USERPASSWORD
in a .dodsrc/.daprc file. The user and password in .netrc must not
be escaped. This is now documented in docs/auth.md
The fix for #2 actually obviated #1. Now, internally, the user and pwd
are stored separately and not in the user:pwd format. They are combined
(and escaped) only when needed.
DAPRCFILE. Note that the value of this environment
variable should be the absolute path of the rc file, not
the path to its containing directory.
2. fixup testauth.sh and add some new tests
3. synch oc
