MFC r298304:
Fix issues identified by Coverity
- Always munmap memory regions after mmap'ing them. - Make sure getpagesize() returns a value greater than 0 and use a cached value instead of always calling getpagesize(3). - Remove intermediate variable for assigning from $TMPDIR if set in the environment to eliminate warnings about pointer conversions with "/tmp", and to mute an invalid buffer overflow concern from Coverity (snprintf and tacking on a NUL terminator was alleviating that concern before). - Remove useless self-test of psize before it's initialized. - Check the return values of getrlimit/setrlimit.
Cosmetic changes: - Replace a `(void*)0` with NULL. - Do some minor whitespace clean up. - Remove an unnecessary cast to mmap. - Make all munmap calls use ATF_REQUIRE_MSG instead of using the:
> if (munmap(..) == -1) > atf_tc_fail(..)
idiom. Employ the new idiom consistently when calling munmap.
