Dana Robinson b9dbabc152 VFD SWMR: Sync with develop (#811)
* Normalization with develop

* Removes checks and work-arounds for strtoll and strtoull (#769)

* Removes checks for (v)snprintf, which are C99 (#772)

* Update missing release note info. (#776)

* Replaces the H5_OVERRIDE macro with override (#773)

The macro is no longer necessary now that we require C++11.

* Cleans up some POSIX header bits in H5private.h (#783)

* Removes outdated checks for ways inline might be defined (#781)

These are obsolete now that we require C99.

* Removes checks for system(), which is C89/90 (#782)

* Removes C++ dependency on H5private.h (#774)

* Removes C++ dependency on H5private.h

Most C API calls have been removed, aside from a few uses of free,
where we just dropped the 'HD'. A couple of H5_ATTR_UNUSED macros
were also replaced with (void) statements.

* Committing clang-format changes

Co-authored-by: github-actions <41898282+github-actions[bot]@users.noreply.github.com>

* Further simplifies Autotools type size checks (#789)

Also fixes an issue where clock_gettime and difftime are not detected
due to earlier simplifications of this code.

* Release Note (#784)

* Normalization of CMake H5pubconf.h with Autotools (#791)

Mostly just moving things around and changing the comments to keep the
delta small. The only symbol change is that for curl/curl.h which I
changed to H5_HAVE_CURL_CURL_H to match the Autotools. This symbol
is not used in the library and is just an artifact of the checks.

* Fix tools test (#794)

* Removes ancient Autotools cruft (#790)

* Reorganization of C and POSIX headers in H5public.h & H5private.h (#793)

* Reorganization of C and POSIX headers in H5public.h & H5private.h

Consolidated and removed duplicates

* It turns out Windows has sys/types.h

Co-authored-by: Larry Knox <lrknox@hdfgroup.org>

* Removes checks for signal and set/longjmp, which are C89 (#798)

Also removes checks for setjmp.h and stddef.h

* Assume frexpl/f and fabsl/f, which are C99 (#799)

* Assume the library has C99 types in C++ type code (#806)

* Assume the library has C99 types in C++ type code

* Committing clang-format changes

Co-authored-by: github-actions <41898282+github-actions[bot]@users.noreply.github.com>

* Removes obsolete equivalents of C99's __func__ (#800)

* Cleans up POSIX/C bits in H5private.h (#804)

* Cleans up POSIX/C bits in H5private.h

* Assume difftime exists (C89)
* Reorg AC_CHECK_HEADERS so headers are in alphabetical order
* Split off networking-related AC_CHECK_HEADERS
* Remove unused UNAME_CYGWIN from configure.ac
* Remove checks for unused sys/timeb.h
* Tidying pass over H5private.h HD prefix macros
* Tidy H5win32defs.h
* Add HD prefix to various scanf calls

* Committing clang-format changes

* Fixes to the alarm(2) code used in the tests to make Windows happy

Co-authored-by: github-actions <41898282+github-actions[bot]@users.noreply.github.com>

* Brings the tools getopt(3) replacement into the main library (#803)

* Moves get_option from the tools library to the C library

* Adds H5 prefix to get_option call and variables

* Renames the H5_get_option long options struct and enum

* Removes type guesses when C99 types are missing (#807)

* Assume C99 types exist in H5detect.c (#808)

* Fixes parallel issues from recent C99 changes

* Adds MPE FUNC --> __func__ changes missed in earlier PRs

* Fix typo

* Fixes parallel issues from recent C99 changes (#809)

* Fixes parallel issues from recent C99 changes

* Adds MPE FUNC --> __func__ changes missed in earlier PRs

* Even more missed FUNC --> __func__ macros

* Removes remaining H5_TIME_WITH_SYS_TIME cruft (#810)

Mostly from CMake
