Add the "http_proxy" option and its handling to the "tls" protocol,
pass the option from the "https" protocol.
The "https" protocol already defines the "http_proxy" command line
option, like the "http" protocol does. The "http" protocol properly
honors that command line option in addition to the environment
variable. The "https" protocol doesn't, because the proxy is
evaluated in the underlying "tls" protocol, which doesn't have this
option, and thus only handles the environment variable, which it
has access to.
Fixes#7223.

These files are technically a series of planar mono tracks.
If the "music" flag is set, merge the packets from the two
mono tracks, essentially replicating:

64 bits are needed in order to retain the uid values of Matroska
chapters; the type is kept signed because the semantics of NUT chapters
depend upon whether the id is > 0 or < 0.

Up until now, there has been no check that each chapter has a unique id;
there was only a check for whether a chapter id is zero (this happens
often when the chapters originated from a format that lacks the concept
of chapter id and simply counts from zero) which is invalid in Matroska.
In this case the chapter ids are offset by 1 to make them nonnegative.
Yet offsetting won't fix duplicate ids, therefore this is changed to
simply create new chapter uids when the input chapter uids don't conform
to the requirements of Matroska (in which case it can be presumed that
they did not originate from Matroska, so that we don't need to bother
to preserve them).

The test program for the FIFO muxer allocates a buffer without padding
and wraps it into a packet via av_packet_from_data(). This is an API
violation. Furthermore, said buffer leaks in case av_packet_from_data()
fails. Fix both of these issues by using av_new_packet() instead.

If one of the two results of a ternary conditional is a pointer to void,
the type of the whole conditional operator is a pointer to void, even
when the other possible result is not a pointer to void. This loophole
in the type system has allowed mxf_read_local_tags to have a pointer of
type pointer to MXFMetadataSet that actually points to an MXFContext.

Commit 8c8e5d5286 added a way to reduce
seek time by waiting for the windowed tcp packets instead of creating a
new socket connection. It implemented this by overwriting
s->short_seek_threshold in avio_seek(). However,
s->short_seek_threshold could already be set and be higher than the
threshold set by the protocol (i.e. s->short_seek_threshold is set in
ff_configure_buffers_for_index()).
This new feature was only enabled for tls connections in
70d8077b79. As in Ticket #9148 it reduced
performance because instead of waiting to refill the AVIOContext buffers
with an existing connections, a new HTTP request was often made instead.
Fixes Ticket #9148.

open_url_keepalive() unsets the options when it uses them, this
includes the offsets for the Range: header. When using the HLS
tag #EXT-X-BYTERANGE along with multiple files, the range options
must be preserved after open_url_keepalive() returns EOF so that
the new file can be opened. Failure to do this results in ignoring
the #EXT-X-BYTERANGE tag and reading the wrong bytes of the file.
To fix it, reset the options before calling io_open() following
open_url_keepalive() reaching EOF
