Remove a couple checks for _MSC_VER in atomic.h that are no longer
required.
Lots of (mostly) documentation changes to improve the internal and external
API documentation generated by doxygen.  Also marked a whole bunch of
functions as deprecated or unimplemented to give guidance to users and
developers about how the API may change in future versions (ie, 0.2.x).
Add functions to libcmyth and librefmem to return their version info.
Add 2 new event types, ERROR and COMMFLAG_START.  Also, generate a unique
hostname on event connections to ensure that all events get delivered.
Start caching the myth protocol version of each backend to avoid
re-negotiating the protocol version for each connection.
Add support for Myth protocol versions 76 and 77.
Add support for the ALLOW_SHUTDOWN and BLOCK_SHUTDOWN myth protocol
commands.
Replace the library wide mutex with individual mutexes on certain data
structures.
Add cmyth_proginfo_stop_recording() and cmyth_proginfo_check_recording().
Update the mythping example app to allow it to display information about
the MythTV recorders, scheduled shows, and upcoming recordings.
Add a bunch of recorder and live TV improvements.
First pass at rewriting the live TV internals.
Improve live TV channel changing by declaring it complete when there is
recording data available, instead of just sleeping.
Fix some misc bugs in libcmyth:

    - Change cmyth_rcv_okay() and add cmyth_rcv_match() since the "OK"
      responses can be in either upper or lower case.
    - Fix cmyth_conn_connect_pathname() to error out if a connection
      handle is not provided.
    - Ensure that calls to select() and recv() are retried if interrupted
      by a signal.
Ensure libcmyth is built against the local version of librefmem.
Add a patch from anstein on Github for IPv6 support.
Fix the previous commit which broke the ability to create connections to
a backend on BSD platforms (at least OS X and NetBSD).
Fix a few minor compile problems seen with NetBSD.
Fix a few warnings seen with the clang static analysis tool.
Fix a few more problems found with scan-build and clang 3.4 on OS X.
