This gets us back to using vfork now our ARM vfork assembler stub is
fixed, and adds the missing thread safety for the 'pidlist'.
Bug: 5335385
Change-Id: Ib08bfa65b2cb9fa695717aae629ea14816bf988d
The declaration for alphasort() in <dirent.h> used the deprecated:
int alphasort(const void*, const void*);
while both Posix and GLibc use instead:
int alphasort(const struct dirent** a, const struct dirent** b);
See: http://pubs.opengroup.org/onlinepubs/9699919799/functions/alphasort.html
This patch does the following:
- Update the declaration to match Posix/GLibc
- Get rid of the upstream BSD code which isn't compatible with the new
signature.
- Implement a new trivial alphasort() with the right signature, and
ensure that it uses strcoll() instead of strcmp().
- Remove Bionic-specific #ifdef .. #else .. #endif block in
dirent_test.cpp which uses alphasort().
Even through strcoll() currently uses strcmp(), this does the right
thing in the case where we decide to update strcoll() to properly
implement locale-specific ordered comparison.

This code is taken directly from netbsd unmodified.
