Each of the 16 bytes of a GUID is written as a two-character
hex value and three hyphens, leading to a length of 35.
GCC 13 emits a -Wformat-truncation= warning because of this.

It is undefined behaviour even in cases where it works
(it works because it is only a const uint8_t* vs. uint8_t* difference).
Instead add a cbuf parameter to pass a const buffer (for writing)
as well as a parameter indicating whether we are reading or writing;
retry_transfer_wrapper() itself then uses the correct function
based upon this information.

av_image_copy() accepts const uint8_t* const * as source;
lots of user have uint8_t* const * and therefore either
cast (the majority) or copy the array of pointers.
This commit changes this by adding a static inline wrapper
for av_image_copy() that casts between the two types
so that we do not need to add casts everywhere else.

when ffurl_read() has been turned into a static inline function
different from the actually used function ffurl_read2().

mxf_match_uid() accepts two const UID and a len parameter.
UID is a typedef for an array of 16 uint8_t, so the const UID
parameter is actually a pointer to const uint8_t.
The point of mxf_match_uid() is to check whether the initial
part of two UIDs match; the length of said part is given
by the len parameter. Once an incomplete UID has been passed
to mxf_match_uid() (albeit with the correct len, so safe),
which makes GCC emit -Wstringop-overread warnings.
Fix this by using a const uint8_t[] as type; it is more
natural for incomplete UIDs.

Therefore use a proper prefix for this API, e.g.
ff_init_vlc_sparse -> ff_vlc_init_sparse
ff_free_vlc -> ff_vlc_free
INIT_VLC_LE -> VLC_INIT_LE
INIT_VLC_USE_NEW_STATIC -> VLC_INIT_USE_STATIC
(The ancient INIT_VLC_USE_STATIC has been removed
in 595324e143, so that
the NEW has been dropped.)
Finally, reorder the flags and change their values
accordingly.

Not every user of idctdsp.h wants to initialize an IDCTDSPContext;
e.g. the proresdsp only uses ff_init_scantable_permutation()
and the IDCT permutation enum; similarly for cavsdsp and wmv2dsp.
Using a forward declaration here avoids an avcodec.h dependency
in the relevant files.

Due to non-byte-alignment a read of 32 bits guarantees only
25 usable bits; therefore get_bits_long() (which is used to
potentially read more than 25 bits) performs two reads in case
it needs to read more than 25 bits and combines the result.
Yet this is not necessary: One can just read 64 bits at a time
to get 32 usable bits (57 would be possible). This commit does so.
This reduced the size of .text by 30144B for GCC 11.4 and 5648B
for Clang 14 (both with -O3).
(get_bits_long() is a building block of show_bits_long()
and get_ue_golomb_long(), so this patch affects these, too.)

It is only included because two very rarely used functions
use pointers to URLContexts; use struct URLContext instead.
Also move ffio_geturlcontext() so that one can avoid
a forward declaration of struct URLContext (which would be
