AAC encoder: tweak rate-distortion logic

This patch modifies the encode frame function to
retry encoding the frame when the resulting bit count
is too far off target, but only adjusting lambda
in small, incremental step. It also makes the logic
more conservative - otherwise it will contend with
bit reservoir-related variations in bit allocation,
and result in artifacts when frame have to be truncated
(usually at high bit rates transitioning from low
complexity to high complexity).

AAC encoder: simplify and speed up find_min_book

Trivial change to simplify the small but hot
find_min_book function. The new form is easier to
understand and faster.

configure: Force mingw's ld to keep the reloc section

Binutils will always strip the relocation information from executable
files even if it needs it (dynamicbase/ASLR).  We can work around this
by using the pic-executable flag combined with setting the correct entry
point since apparently ld forgets what that should be.  This problem
affects both 32 and 64-bit mingw-w64.

avcodec/dvdsubdec: don't use a NULL log context

avcodec/dvdsubdec: reject some broken packets

If cmd_pos is broken, this would just keep accumulating packets in the
reassembly buffer, until it fails and flushes the buffer on overflow.
Since packets are usually rather small, this will take a lot of subtitle
packets. The perceived effect is that subtitles are not displayed
anymore after the faulty packet was passed to the decoder.

I'm not terribly sure about this, but on the other hand this code is
active only when fragmented packets need to be reassembled.

Fixes sample file in trac issue #4872.

avcodec/dvdsub: fix partial packet assembly

Assuming the first and second packets are partial, this would append the
reassembly buffer (ctx->buf) to itself with the second
append_to_cached_buf() call, because buf is set to ctx->buf.

I do not know a valid sample file which triggers this, and do not know
if packets can be split into more than 2 sub-packets, but it triggered
with a (differently) broken sample file in trac issue #4872.

avformat/hls: fix some cases of HLS streams which require cookies

happens with HLS streams which use encryption and require preserving

avcodec/dvdsubdec: fix indentation

avformat/assdec: do not drop duplicate subtitles

Duplicates are perfectly legitimate with this format. A correct
renderer will typically show them stacked.

avformat/vobsub: do not attempt to check duplicate subtitles

Some .idx files actually contain duplicate subtitle events:

timestamp: 00:07:52:600, filepos: 00004e800
timestamp: 00:07:52:600, filepos: 00004f800

The second will be dropped, because it has same pts, duration, and text
(the text is just a dummy empty string; the real data is retrieved when
actually reading vobsub subtitle packets).

Dropping this is probably not intended/safe, so avoid it.

See trac issue #4872 for a sample. This patch doesn't fix decoding of
the sample, though.

avformat/subtitles: make dropping duplicate events optional

avformat/vobsub: compare correct packet stream IDs

The stream ID is essentially an arbitrary number defined by the .idx
file headers. They have to match the IDs in the .sub stream. The vobsub
demuxer assumed the IDs would just start from 0, increassing by 1 for
each stream. This is not correct. In the sample I had, the IDs were
starting from 1, leading to no subtitles being displayed at all.

Fix this by using the correct stream ID.
