Also use a unsigned constant for the shift calculation, as 1 << 31 is
undefined for int32_t. This is also fixed oggparsetheora.

This fixes ubsan runtime error: shift exponent is too large for
32-bit type 'int'

Fixes ticket #5117

ff_clz is faster, and uses an intrinsic (at the moment on GCC). exp2 is
a wasteful function for a simple integer exponentiation.

Untested.

Fixes Ticket #5032

The samples in Ticket #5032 is using \r\r\n as line breaks.  Since we
already are handling \r, or \n, or \r\n as line breaks, \r\n\n will be
considered as a double line breaks. This is an issue because
ff_subtitles_read_text_chunk() will as a result stop extracting a chunk
after just one line.

So instead of parsing the SRT by "chunks" (which means splitting every
double LB), this new parser is detecting timing lines, and split the
events on this basis. While this sounds safe and simple, it needs to
take into account the event number preceding the timing line while
handling situations such as:

 - event number starting at 0 or actually any number instead of 1
 - event numbers not being ordered at all
 - event number being followed by text garbage (this really happened,
   see Ticket #4898)
 - event payload containing one or multiple number (a protagonist saying
   a count-down, a date or whatever) which could be confused with a
   chapter number
 - event number being empty (see Ticket #2167)
 - all kind of weird line breaks can appear randomly like wild pokémons
 - untrustable line breaks (Ticket #5032)

The sample madness.srt tries to sum up most of this into one sample,
ticket5032-rrn.srt is the file containing \r\r\n line breaks. and
empty-events-2167.srt contains empty events.

This can happen if s->ls changes from 0 to 1, but picture allocation is
skipped due to s->interlaced.

In that case ff_jpegls_decode_picture could be called even though the
s->picture_ptr frame has the wrong pixel format and thus a wrong
linesize, which results in a too small zero buffer being allocated.

This fixes an out-of-bounds read in ls_decode_line.
