The sbr_qmf_window_us array is basically symmetric around its middle
element and therefore the latter half is currently initialized from the
first half at runtime. Yet because the first half is initialized, the
array can't be placed in .bss at all, so that one gains nothing from not
already initializing the whole array statically. Therefore this commit
does exactly this.
(There are two exceptions to the symmetry: Elements 384 and 512 are the
negations of their mirror element; for the fixed-point decoder, Q31(-x)
does not equal -Q31(x). In order to keep the array exactly the same, the
latter form has been used for these two elements.)

Finding the best codebook involves comparing different paths, where each
path is a sequence of several decisions (namely which codebook to use).
Up until now, these sequence was encoded in a NUL-terminated string and
the actual decisions were encoded as ’\0'..'\3' (which encoded 0..3).
This commit modifies this to actually encode it via 0..3 by switching
away from a C-string to a simple array with an explicit length field.

Modifying static storage must not happen because of multithreading
(except initialization of course), so add const to the pointed-to type

These two are always called directly after each other (with the
exception of the calls in mpeg_decode_init() where some irrelevant
modifications of the avctx (which could just as well be done before
ff_mpv_decode_defaults(), because it doesn't have a pointer to the
AVCodecContext at all and therefore can't see these modifications at
all) are performed in between), so merge ff_mpv_decode_defaults() in
ff_mpv_decode_init().

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.

This was introduced in version 4.6. And may not exist all without an
optional package. So to prevent a hard dependency on needing the Linux
kernel headers to compile, make this optional.
Also ignore the status of the ioctl, since it may fail on older kernels
which don't support it. It's okay to ignore as its not fatal and any
serious errors will be caught later by the mmap call.
'void *' is too flexible, since we can derive info from
AVFilterContext*, so we just unify the interface with this data
structure.
