When delete_segments hls_flag is specified, deleting old segments may
fail in certain cases when use_localtime_mkdir is in effect and
hls_segment_filename expression contains subdirs. This patch fixes this
behaviour.

Additional/Modified FATE tests improve code coverage from 63.7% to 98.1%.
Changed fate-suite sample files:
* filter/hdcd-mix.flac (958K) added. It is a much better test than
filter/hdcd.flac (910K), which is now unused, but can't be removed.
* filter/hdcd-fake20bit.flac (168K) added. It is the first second of
filter/hdcd.flac, with the 16-bit LSB copied into bit 20 of a 24-bit
stream. There isn't an actual non-16-bit HDCD sample available to test.

The checked bitstream reader does that already. To allow parsing of
superframes split over a packet boundary, we always decode the last
superframe in each packet at the start of the next packet, even if
theoretically we could have decoded it. The last superframe in the
last packet is decoded using AV_CODEC_CAP_DELAY.
in filenames
Putting date/time values into segment filenames is very usefull.
But to produce non-conflicting segment filenames with -use_localtime
option with date/time
values in hls_segment_filename option, sometimes is not enough.
Like in cases when multiple segments produced in the same second.
But hlsenc currently does not make possible to use segment index (%d) at
the
same time whe use_localtime is in effect, due to identifier conflict.
This patch makes possible to use strftime identifiers and still put
segment index (%d) at same time in segment filenames by introducing
second_level_segment_index flag. When -use_localtime is active,
identifier %d is for month day index, so %%d is the segment index
placeholder. This enhanced behaviour only exists when new
second_level_segment_index flag is specified.
For instance putting 'segment_%Y%m%d%H%M%S_%%05d.ts' value into
-hls_segment_filename option and specifing -hls_flags
second_level_segment_index and -use_localtime 1, may produce segment
filename as 'segment_20161230235758_00002.ts'
An example:
ffmpeg -loglevel info -y -f lavfi -i color=c=red:size=640x480:r=25 -f
lavfi -i anullsrc=r=44100:cl=stereo -c:v mpeg2video -g 25 -acodec aac
-cutoff 20000 -ac 2 -ar 44100 -ab 192k -f hls -hls_time 3 -hls_list_size
5 -hls_flags delete_segments+second_level_segment_index -use_localtime 1
-hls_segment_filename "segment_%Y%m%d%H%M%S_%%05d.ts" stream.m3u8
will produce segments filenames:
....
segment_20161227005902_00013.ts
segment_20161227005902_00014.ts
segment_20161227005902_00015.ts

initial_prog_date_time shouldn't be adjusted when deleting segments

with use_localtime parameter hlsenc may produce identical filenames for
different but still existing segments. It happens when
hls_segment_filename contains
syntacticaly correct but inadequate format parameters. Currently there
is no any log message when such a situaton occurs but these cases should
be avoided in most times. This patch generate warning log messages in
these cases.
