mpegts: do not export empty language tags

Signed-off-by: Anton Khirnov <anton@khirnov.net>
configure: Do not add extralibs to avresample .pc file

The library does not have external dependencies.
build: Support executable only ldflags

The options is useful to build position-independent executables on
hardened systems (e.g. Android L and Gentoo Hardened).
http: Provide an option to override the HTTP method

Certain servers accept only PUT as valid method.
http: Do move the class instantiation in the conditional block

Remove a warning if https support is disabled.
configure: add support for neon intrinsics
aarch64: NEON intrinsics dct_unquantize_h263.

Intrinsics only used on aarch64 since the existing ARMv7 NEON asm
is slightly faster (Cortex-A9, gcc-4.8, micro-benchmarks and full
decoding time).

Support raw dvdsub palette as stored on normal dvd's

This is how the palette is stored on dvd's. Currently
only xbmc passes the palette information to libavcodec
this way.
Check return value of avio_seek and avoid modifying state if it fails

The code still modifies state if the timestamp is not found. Not
sure exactly how to avoid that.
