This otherwise breaks the build on Android and Windows. The flag is
required on some Linux builds, and is readded in a subsequent commit.

In investigating x86/sse2 issues in recent webrtc-audio-processing-0.2
release, I found that it was possible for libwebrtc_audio_processing to
contain undefined symbols.

Attached is a patch that addresses this:
* adds -Wl,--no-undefined to libwebrtc_audio_processing_la_LDFLAGS
* adds explicit -lpthread linkage (else, there are undefined references
  to pthread-related symbols)

This corresponds to:

Chromium: 6555f9456074c0c0e5f7713564b978588ac04a5d
webrtc: c8b569e0a7ad0b369e15f0197b3a558699ec8efa

On x86, SSE optimisations are always compiled in, and used based on
runtime checks.

On ARM, we try to autodetect NEON support (with an option of runtime
detection). This has not been build-tested on ARM yet.

This leaves MIPS to be done.

This isn't used it, but let's keep it up to date

Corresponds to upstream commit 524e9b043e7e86fd72353b987c9d5f6a1ebf83e1

Update notes:

 * Pull in third party license file

 * Replace .gypi files with BUILD.gn to keep track of what changes
   upstream

 * Bunch of new filse pulled in as dependencies

 * Won't build yet due to changes needed on top of these

Corresponds to upstream commit 524e9b043e7e86fd72353b987c9d5f6a1ebf83e1

Update notes:

 * Moved src/ to webrtc/ to easily diff against the third_party/webrtc
   in the chromium tree

 * ARM/NEON/MIPS support is not yet hooked up

 * Tests have not been copied
