44bb776f13 avcodec/mpegvideo_enc: Make mpv_encode_defaults thread-safe 
This is a prerequisite for making any encoder that uses
ff_mpv_encode_init() init-threadsafe; it already makes the AMV,
the MJPEG and the MPEG-1/2 encoders init-threadsafe.

6e8fcd9c56 avcodec/mpeg12: Don't initialize encoder-only parts of RLTable 
ff_mpeg12_init_vlcs() currently initializes index_run, max_level and
max_run of ff_rl_mpeg1/2; yet the only user of these fields is the
MPEG-1/2 encoder which already initializes these tables on its own.
So remove the initializations in ff_mpeg12_init_vlcs(); this also
simplifies making ff_mpeg12_init_vlcs() thread-safe.

628d02a611 avcodec/speedhqenc: Call correct function 
Up until now, the SpeedHQ encoder called a wrong function for init:
void ff_init_uni_ac_vlc(const uint8_t huff_size_ac[256],
                        uint8_t *uni_ac_vlc_len);
Yet the first argument actually used is of type RLTable; the size of
said struct is less than 256 if the size of a pointer is four, leading
to an access beyond the end of the RLTable.

This commit fixes this by calling the actually intended function:
init_uni_ac_vlc() from mpeg12enc.c. It was intended to use this
function [1], yet doing so was forgotten when the patch was actually
applied.

4e26520039 avcodec/mpeg12enc: Disallow using MPEG-2 intra VLC table for mpeg1video 
Using MPEG-2 intra VLC tables is spec-incompliant for MPEG-1 and given
that an MPEG-1 bitstream can't signal whether MPEG-2 intra VLC tables
have been used the output is broken. Therefore this option is removed
immediately without any deprecation period.

ef3c1670d4 avcodec/mpeg12enc: Always initialize MPEG-2 intra VLC table lengths 
The MPEG-1/2 encoders initialize several tables once during the first
time one of the encoders is initialized; the table for MPEG-2 intra VLC
lengths is only initialized if it is used for this encoder instance.
This implies that if the first MPEG-1/2 encoder to be initialized does
not use it, it will never be initialized even if a later encoder
instance makes use of them. Fix this by initializing this table
unconditionally.

717503f716 put_bits: make avpriv_align_put_bits() inline 
This function is so extremely simple that it is preferable to make it
inline rather than deal with all the complications arising from it being
an exported symbol.

Keep avpriv_align_put_bits() around until the next major bump to
preserve ABI compatibility.

Since there is no information about the source format, "unspecified"
is the correct value to write here.

All tests using the MPEG-2 encoder are updated, as this changes the
header on all outputs.
