"unistd.h TEMP_FAILURE_RETRY generates warning when used with syscall
that returns unsigned int".
The Android version of this macro will generate a signed/unsigned
comparison when used with a syscall function that returns an unsigned
value such as inet_addr(), which returns in_addr_t, which is defined as
an unsigned int. By casting the result to an int before the macro
processes it, and then casting it back to an in_addr_t after the macro
returns it we are able to avoid the signed/unsigned comparison, and so
avoid the signed/unsigned comparison warning.

Split directory_posix -> directory_(android|linux|macos)
This allows us to cleanly make Android-specific changes to
directory_android.cc
Copy all _linux files to _android files and edit as needed to account
for the differences between Linux and Android:
+ getcwd(0, NULL) doesn't work on Android, have to emulate
+ Android doesn't have a '/tmp' directory, have to emulate
+ Android doesn't provide mkdtemp(), have to emulate.
+ Small differences in the available system include files.
+ Use pthread_cond_timedwait_monotonic instead of
pthread_condattr_setclock
