As in https://codereview.chromium.org/24024007, except the monitor->Wait
is now called in a loop with a guard, to ensure we actually do get notified.

Also, now correctly exiting the thread if we have no more child
processes, using the initialize/terminate mutex as guard.

cbracken@google.com a6ace331f3 Replaced strerror() calls with threadsafe strerror_r(). 
Mac/Android use the XSI-compliant definition of strerror_r() which stores the message in the passed-in buffer.

Linux uses the GNU-specific definition of strerror_r() which takes a buffer and returns the message in a char* (which may or may not be the passed-in buffer).

kustermann@google.com ba62bae621 Fix for leaking file descriptor issue 
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()).

  This allows us to cleanly make Android-specific changes to

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
