AVbin 10 Release Notes

- Updated to Libav trunk as of 2012-08-12 (which finally fixed the .ogg decoding
  problems on all platforms!).

- Added the avbin_get_info() function and removed the avbin_get_libav_commit()
  and avbin_get_libav_version() functions that I tried out in AVbin 9, which I
  am now pretending never got released.

  avbin_get_info() returns an _AVbinInfo struct (typedef AVbinInfo) with the
  following members (all strings except where indicated):
  - version                 > integer, same as avbin_get_version()
  - version_string          > potentially includes prerelease info,
                              for example: "10-beta1"
  - build_date              > %Y-%m-%d %H:%M:%S %z
  - repo                    > Git URL
  - commit                  > Git commit hash
  - backend                 > "libav" or "ffmpeg"
  - backend_version_string  > Most recent backend version tag or trunk and date
                              i.e. "v0.8.3" or "trunk (Wed Aug 22 19:58:46 2012 -0400)"
  - backend_repo            > Backend git URL
  - backend_commit          > Backend git commit hash

- Added AVbinOptions typedef (struct _AVbinOptions) for use with the new
  avbin_init_options() function.

- Added avbin_init_options() to handle initialization options.  avbin_init() now
  creates an AVbinOptions with default settings and calls avbin_init_options()
  under the hood.  Future versions of AVbin may have new AVbinOptions* structs
  that you can pass to avbin_init_options().  Currently, the only option is how
  many threads you would like avbin to use for decoding (defaults to 1, using
  0 [autodetect] is recommended).

- Updated avbin_have_features() with new features to check for.
  "options" > presence of avbin_init_options(), AVbinOptions, and multithreading
  "info"    > presence of avbin_get_info(), AVbinInfo

- Adapted the underlying C code implementation to upstream API changes, as well
  as switching to more portable data types across the board.  This work was
  almost entirely pulled from Jernej Virag's fork, so kudos to him!

- Implemented multithreading support inspired by Jernej's work.  If you want
  the library to use multiple threads, please see avbin_init_options() in the
  documentation.

- Overhauled all configure options and Makefile commands so that all six
  supported platforms have very similar builds now.  Bz2 and Gzip compression is
  enabled on all platforms now, for example.  Every platform also had to have
  configure and make options adjusted to compensate for new versions of Xcode
  and OS X, new versions of Linux, and the new version of Libav.

- Overhauled the build script.  All build errors now have descriptive messages.
  The options may now be specified at any argument position.  The --fast option
  now compiles with more processes at once.  The --clean option now does a
  better job cleaning.  The libav submodule is automatically updated before
  building.

- Overhauled the dist script, which now generates binary installers for all
  platforms

- The OS X version is now a universal library containing both 32-bit and 64-bit
  code.

- The OS X release is now a package installer, instead of a tarball.

- The Linux release is now a compressed binary installer instead of a tarball.

- The Windows release is now an executable installer instead of a zipfile.

- All installers now present and require acceptance of the license.

- Updated the Makefile for the avbin_dump example so that it compiles on Linux

- Updated the avbin_dump example:
  - Command-line arguments are now processed position-independently
  - The new help argument (-h, --help) displays usage
  - The new verbose argument (-v, --verbose) enables printing out information
    about each packet decoded from a media file.  (Previously you had to modify
    the source code and recompile to enable this).
  - The verbose output now includes timestamps (in microseconds).

- Updated the online API documentation: http://avbin.github.com/docs/

- Ran the repository through `git filter-branch` and eliminated all of the
  ffmpeg source code, which shrinks the repo size to 528K (much better than
  about 100MB!!)  NOTE: If you have a pre-filter clone, you will need to
  either make a new clone (easy), or rebase:

- Configured a buildbot master.  Configured buildbot slaves for each platform.

- Resolved issues 11-17, 19, 23-33, and 36-38.
