avformat/hls: ignore http_persistent for segments requring crypto

Encrypted HLS segments have regular http:// urls, but open_input()
actually prefixes them with crypto+ before calling open_url(), so
they end up using the crypto protocol and not the http protocol.

This means invoking ff_http_do_new_request will fail, so we avoid
calling it in the first place. After the earlier http.c commit,
the failure results in a warning printed to the user. In earlier

all good advice.

But there are dummy atomics too, so the atomic check won't help with
ensuring correctness absolutely. You gain very little.

Also, for debugging, you can just raise the ASSERT_LEVEL, and then

x86inc: AVX-512 support

AVX-512 consists of a plethora of different extensions, but in order to keep
things a bit more manageable we group together the following extensions
under a single baseline cpu flag which should cover SKL-X and future CPUs:
 * AVX-512 Foundation (F)
 * AVX-512 Conflict Detection Instructions (CD)
 * AVX-512 Byte and Word Instructions (BW)
 * AVX-512 Doubleword and Quadword Instructions (DQ)
 * AVX-512 Vector Length Extensions (VL)

On x86-64 AVX-512 provides 16 additional vector registers, prefer using
those over existing ones since it allows us to avoid using `vzeroupper`
unless more than 16 vector registers are required. They also happen to
be volatile on Windows which means that we don't need to save and restore
existing xmm register contents unless more than 22 vector registers are
required.

Big thanks to Intel for their support.

avformat/hls: add http_multiple option

This improves network throughput of the hls demuxer by avoiding
the latency introduced by downloading segments one at a time.

The problem is particularly noticable over high-latency network
connections: for instance, if RTT is 250ms, there will a 250ms idle
period between when one segment response is read and the next one
starts.

The obvious solution to this is to use HTTP pipelining, where a
second request can be sent (on the persistent http/1.1 connection)
before the first response is fully read. Unfortunately the way the
http protocol is implemented in avformat makes implementing pipleining
very complex.

Instead, this commit simulates pipelining using two separate persistent
http connections. This has the advantage of working independently of
the http_persistent option, and can be used with http/1.0 servers as
well. The pair of connections is swapped every time a new segment starts
downloading, and a request for the next segment is sent on the secondary
connection right away. This means the second response will be ready and
waiting by the time the current response is fully read.
