Update README.md

Changed to fork-URL
Revert "Update README.md"

This reverts commit cbe00b191f08670cfb34d5029e0b06aad4509f16.
Fix fork and clone text

The previous commit was an accidental revert.
owr_local: add G_{BEGIN,END}_DECLS
Move build instructions out to a wiki page

This avoids having too much information in the README.md
owr_local_media_source: videorate drop only not set to TRUE.

This is to prevent renegotiation if a new framerate that is higher than the original value is set.
owr_payload: Set bitrate on payload after binding instead of on encoder before binding.

This keeps the synchronization between the OwrPayload object and the encoder.
Update build scripts

configure.ac: The OpenWebRTC GStreamer plugins install no pkg-config file

And they are only a runtime dependency, no build dependency.
build: Don't use -pedantic and -ansi

They will fail the build too easily with external headers and don't do what
one would expect. Instead let autoconf figure out the right compiler flags for
using a standard conformant C compiler.
nice: Version 0.1.7.1 or newer is required to build
owr_local_media_source: Work around wrong compiler warning

owr_local_media_source.c: In function 'owr_local_media_source_get_pad':
owr_local_media_source.c:119:10: error: 'source' may be used uninitialized in this function [-Werror=maybe-uninitialized]
     if (!gst_element_link(a, b)) \
          ^
owr_local_media_source.c:296:17: note: 'source' was declared here
     GstElement *source, *capsfilter = NULL, *tee;
build: Requires gstreamer-app-1.0 and gstreamer-video-1.0 too
transport/owr_candidate: Use - instead of _ to prevent assertions with G_PARAM_STATIC_STRINGS
build: Fix linking of the bridge daemon
Require GStreamer >= 1.4 and write the version only once
build: Make sure we have the scripts submodule
Update scripts

A bug was fixed in the gst-plugins-bad build script

libopenwebrtc.exp: Remove deprecated symbols

A work-in-progress plugin was removed from the build scripts which
caused some symbols to disappear. This patch just fixes the build of
OpenWebRTC after updating the build scripts.
Removed empty files
