aarch64: vp8: Optimize vp8_idct_add_neon for aarch64
The previous version was a pretty exact translation of the arm
version. This version does do some unnecessary arithemetic (it does
more operations on vectors that are only half filled; it does 4
uaddw and 4 sqxtun instead of 2 of each), but it reduces the overhead
of packing data together (which could be done for free in the arm
version).
This gives a decent speedup on Cortex A53, a minor speedup on
A72 and a very minor slowdown on Cortex A73.

aarch64: vp8: Move the vp8dsp makefile entries to the right places
Even if NEON would be disabled, the init functions should be built
as they are called as long as ARCH_AARCH64 is set.
These functions are part of a generic DSP subsytem, not tied directly
to one decoder. (They should be built if the vp7 decoder is enabled,
even if the vp8 decoder is disabled.)

aarch64: vp8: Fix assembling with clang
This also partially fixes assembling with MS armasm64 (via
gas-preprocessor).
The movrel macro invocations need to pass the offset via a separate
parameter. Mach-o and COFF relocations don't allow a negative
offset to a symbol, which is handled properly if the offset is passed
via the parameter. If no offset parameter is given, the macro
evaluates to something like "adrp x17, subpel_filters-16+(0)", which
older clang versions also fail to parse (the older clang versions
only support one single offset term, although it can be a parenthesis.

arm: Create proper .rdata sections for COFF
As .rodata isn't one of the default created sections for COFF, it was

The existing ".section .rodata" works as intended for ELF though.

libx264: Pass the reordered_opaque field through the encoder
libx264 does have a field for opaque data to pass along with frames
through the encoder, but it is a pointer, while the libavcodec

within the libx264 wrapper, where reordered_opaque values in flight

field to explain this usage, and add a codec capability that allows
detecting whether an encoder handles this field.

This was marked as deprecated (but only in the doxygen, not with an

The avcodec_parameters_to_context() call was freeing and reallocating

some library users like Firefox.
Revert until a better solution is found to internally propagate the filtered
extradata back into the decoder context.

network: Add RFC 8305 style "Happy Eyeballs"/"Fast Fallback" helper function
For cases with dual stack (IPv4 + IPv6) connectivity, but where one
stack potentially is less reliable, strive to trying to connect over
both protocols in parallel, using whichever address connected first.
In cases with a hostname resolving to multiple IPv4 and IPv6
addresses, the current connection mechanism would try all addresses
in the order returned by getaddrinfo (with all IPv6 addresses ordered
before the IPv4 addresses normally). If connection attempts to the
IPv6 addresses return quickly with an error, this was no problem, but
if they were unsuccessful leading up to timeouts, the connection process
would have to wait for timeouts on all IPv6 target addresses before
attempting any IPv4 address.
Similar to what RFC 8305 suggests, reorder the list of addresses to
try connecting to, interleaving address families. After starting one
connection attempt, start another one in parallel after a small delay
(200 ms as suggested by the RFC).
For cases with unreliable IPv6 but reliable IPv4, this should make
connection attempts work as reliably as with plain IPv4, with only an
extra 200 ms of connection delay.
