Mike Hommey f24b476a63 Bug 1559379 - Export C++ allocation functions from mozglue on all platforms. r=froydnj
- On Android, we were already doing it, but using fallible allocations.
- On *nix, it probably doesn't make a difference, but can't hurt. For
  most things in Gecko, operator new/delete are inlined and thus
  replaced by direct calls to the underlying allocator functions
  (moz_xmalloc, malloc, etc.). This may have a benefit for some third
  party libraries that would otherwise go through libstdc++'s to
  eventually end up back into our allocator via the zone allocator
  on macOS and via the exported symbols on others.
- On Windows, because of how some CRT static libraries are, a non-inlined
  operator new (thanks to some disabled STL wrapping) would end up linked
  against the system malloc, causing problems.

Overall, this can only be better. This also reduces the number of places
where we define those functions.

And on Android, this means operator new within mozglue becomes infallible,
which is more consistent with everything else.
