avcodec/rl: Don't pretend ff_rl_init() initializes a RLTable twice
...
It can't any longer, because all users of ff_rl_init() are now
behind ff_thread_once() or the global codec lock. Therefore
the check for whether the RLTable is already initialized can be removed;
as can the stack buffers that existed to make sure that nothing is ever
set to a value different from its final value.
Similarly, it is not necessary to check whether the VLCs associated
with the RLTable are already initialized (they aren't).

avcodec/rl: Allow to create only a few VLC tables

It is not uncommon that only the first one is used; this is similar to
ff_init_2d_vlc_rl().

Move VLC and RL_VLC_ELEM structure definitions to a separate header
...
Use the newly created vlc.h directly instead of including get_bits when needed.
The VLC and RL_VLC_ELEM structures are independent from the bitreader.

Globally rename the header inclusion guard names.

Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.' to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".
