Dennis Heimbigner 90fd1406bc Make use of clock_gettime be conditional.
Re: GH Issue https://github.com/Unidata/netcdf-c/issues/1900

Apparently the clock_gettime() function is not always available.
It is used in unit_test/tst_exhash.c and unit_test/tst_xcache.c.

To solve this, a number of things were changed:
* Move the timing code to a new file unit_tests/timer_utils.[ch]
* Modify the timing code to choose one of several timing methods
depending on availability. The prioritized order is as follows:
    1. If Windows, use the QueryPerformanceCounter mechanism else
    2. Use clock_gettime if available else
    3. Use gettimeofday if available else
    4. Use getrusage if available

Note that the resolution of 3 and 4 is less than 1 or 2.

Misc. Other Changes:
* Move the test in CMakeLists.txt that disables unit tests for WIN32 to unit_test/CMakeLists.txt since some unit tests actually work under Visual Studio.
* Fix some of the unit tests to work under visual studio
* Fix problem with using remove() in zmap_nzf.c
* Remove some warning about use of EXTERNL
