a44c42dc31 avformat/dashdec: Avoid segfault when URL template is unexpectedly missing

Rename is_init_section_common_audio to is_init_section_common_subtitle
for is_common_init_section_exist(c->subtitles, c->n_subtitles).
Because it is checked to subtitles, not audio.

756897eff4 avformat/dashdec: check init_section before use it. 
because there have no Initialization in SegmentTemplate,
so it will have no init_section for init segment file.
but in the is_common_init_section_exist function it will be used for
check to url, url_offset and size, so check init_section
before use init_section.
And fix code style in is_common_init_section_exist,
make the code block short when it too long.

fix ticket: 9062

e9513052b5 avformat/rtsp: Fix build failure when RTP demuxers are disabled 
rtsp.c uses a check of the form "if (CONFIG_RTSP_DEMUXER && ...) {}"
with the intent to make the code compilable even though the part guarded
by this check contains calls to functions that don't exist when the RTSP
demuxer is disabled. Yet even then compilers still need a declaration of
all the functions in the dead code block and error out if not (due to
our usage of -Werror=implicit-function-declaration) and no such
declaration exists for a static function in rtsp.c. Simply adding a
declaration leads to a "used but never defined" warning, therefore this
commit resorts to an #if.

7ccea3bf09 avcodec/xbmdec: get_nibble() minor speed increase, and binary reduction 
Replace av_isxdigit(*ptr) and convert(*ptr) with get_nibble(*ptr) which
returns a valid nibble=={0x00..0x0f} or false==255 for all other values.
This way we only need to work with *ptr once instead of twice.

Removing inline av_isxdigit(x) functions also shrinks executable size.

If we test for {0..9} first, we have tested for 10/16th of all possible
characters first and avoid testing the remaining 6/16th of all possible
characters, which can be either 6/16th lowercase or 6/16th uppercase.

42c636c972 avcodec/xbmenc: Pre-compute variables once for parse_str_int() 
Some compilers are very intuitive, and others are not so much, so let's
pre-compute the variables e and keylen outside the for loop. Ensuring a
minor speed increase regardless of if compiler is smart enough to solve
this improvement for itself, or not.

b6bc981d25 avcodec/xbmenc: substitute end instead of recalculating end 
Minor speed increase, end is calculated before entering parse_str_int(),
so let's take advantage of the value and avoid recalculating twice more.
This also allows parse_str_int() to work with file size larger than int.
