Changes from v3 to v4:
 * Remove src/nacl/plugin.c, libvlc is built without plugin support for nacl
 * Do not replace sigwait on all platforms, but only on nacl
 * vout: remove pp_instance and ppb_graphics3d from vlc_vout_window.h
 * aout: add locking around block usages
 * remove checks for pthread_cond_timedwait_monotonic_np,
   pthread_condattr_setclock from configure.ac
 * use elif in compat/flockfile.c

Changes from v2 to v3:
 * posix/thread_nocancel.c from v2 is now called misc/thread_nocancel.c
 * implemented f{,un}lockfile with newlib/nacl specific functions
 * add a dummy sigwait to compat
 * add a dummy pathconf to compat
 * add posix conforming {send,recv}msg to compat
 * ensure all of RĂ©mis copyright notices are still in place

Changes from v1 to v2:
 * Move android/thread.c to posix/thread_nocancel.c to avoid code duplication in nacl/thread.c
 * video_output: Remove display.c and move NaCl specific code to window.c
 * audio_output: Fixed popping noise when no data available
 * audio_output: Fixed flushing
 * vlc_fixup: Add fixup for TCP_NODELAY
 * Patches have been reordered slightly

Original Description:
This patch series makes it possible to compile VLC for Google Chrome's Native
Client environment. NaCl uses a newlib libc plus several NaCl specific
changes/replacements. This requires some special treatment here and there.
By design most access plugins are not usable in a sane way in NaCl, but for
now UDP and RTP access are working when sufficient permissions are given to
the Chrome App.
Ontop of changes to make a build possible two new modules are added.
video_output/ppapi/: GL module to render video to the Chrome GL context
audio_output/ppapi.c: Audio output to render audio to Chrome

Building for NaCl requires usage of a NaCl toolchain from the NaCl SDK. For
convenience we use webports (https://chromium.googlesource.com/webports) to
build libvlc and it's dependencies. The patches to add libvlc in there will be
pushed for webports once these patches have landed in VLC.

Besides that a demo application using libvlc, exposing part of the libvlc API
as JavaScript, exists and will be published soonish.
