When calling a non-existent executable, a pair of file descriptors will be
created with pipe(). One end goes to the exitcode handler thread, the other end
goes to the epoll() thread.
If an error occurs during process creation, the pipe is still created and the
exit handler thread writes the exitcode to the pipe, but the other file
descriptor is not added to the epoll() set and is therefore leaked. (i.e.
Process_Start ignores the other end of the pipe if exec() failed in
Proces::Start()).

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
