MoonchildProductions#1251 - Part 7: All the posix_m* memory-related stuff, gathered together.
https://bugzilla.mozilla.org/show_bug.cgi?id=1158445 https://bugzilla.mozilla.org/show_bug.cgi?id=963983 https://bugzilla.mozilla.org/show_bug.cgi?id=1542758 Solaris madvise and malign don't perfectly map to their POSIX counterparts, and some Linux versions (especially Android) don't define the POSIX counterparts at all, so options are limited. Ideally posix_madvise and posix_malign should be the safer and more portable options for all platforms.
