ajohnsen@google.com 6949a7bd08 Simplify process exit-code handling on Posix, take 2. 
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.

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()).

ager@google.com 79a0089d38 Change Process.kill to return a boolean instead of throwing an exception when kill fails. 
If the program wants to kill the process after a given time, it is
possible that the process is already dead but has not yet been
reaped. Therefore, there is no way for the programmer to test if the
process is already dead before killing it. Throwing an exception from
kill is not helpful as you will most often have to catch it and do
nothing because you cannot prevent the exception occasionally and
there is nothing you can do as a result of the exception since it
usually means that the process is already dead.

sgjesse@google.com b7485553a2 Fix deadlock in process exit handling 
As glibc allocation routines are not re-entrant avoid calling delete in signal handler.

Instead the message send from the signal handler on process exit contains both the pid and the exit code. The internal _Process object always installs a data handler for the exit message and calls back into C++ to cleanup the resources allocated for running a process.

Changed the ActiveProcess (renamed to ProcessInfo) to form an explicitly linked list.
