6b2c1d1018 avcodec/elbg: Add flags to avpriv_elbg_do()
This is currently unused and it is only added to enable changes
while maintaining ABI compatibility. The type is uintptr_t in order
to potentially accept a pointer argument.

It will be used in future commits to avoid having to allocate and free
all the buffers used.

9e11debb5d avcodec/elbg: Rename elbg_data to ELBGContext
It is in line with our naming conventions for types.
Also change numCB to num_cb for the same reason.

05ccfcb7b0 avcodec/elbg: Merge avpriv_init_elbg() into avpriv_do_elbg()
These functions are always called directly after another with
the exact same arguments. This avoids exporting a symbol;
it also avoids having to perform two calls for every caller.

fe55c31976 lavc/elbg: rename ff_ symbols to avpriv_, so they can be used in shared libs
In particular, allows the use of elbg in other FFmpeg libraries, required
by the pending elbg filter.

987903826b 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_".
