Normalize platform-independence code w/ develop (#2615)

* Normalize platform-independence code w/ develop

* Use C99 types and functions in lieu of C89 work-arounds
* Align key files with develop
    - H5public.h
    - H5private.h
    - H5system.c
    - H5win32defs.h
* Minor fixes elsewhere to support changes in above files
* Incidentally brings Fortran mod directory settings file change over

This does NOT change the configure/build files. Those will still do the
checks needed for the C89 work-around cruft until the perf and perform
code gets cleaned up.

* Add C++98 fixes

* Explicitly set -std=c++98 in Autotools
* Do not include cstdlib in H5public.h (requires C++11)

* Remove redundant stdbool.h include

* Fix alarm issues on Windows

* Bring parallel alarm() changes from develop
