avutil/avassert: Add av_unreachable() and av_assume() macros

Browse Source 
Useful to let the compiler and static analyzers know that
something is unreachable without adding an av_assert
(which would be either dead for the compiler or add runtime
overhead) for this.
The implementation used here enforces the use of a message
to provide a reason why a particular code is supposed to be
unreachable.
