* libswscale: Adds conversions from/to float gray format.Sergey Lavrushkin2018-08-14

* swscale: Add p016 output support and generalise yuv420p1x to p010Philip Langdale2018-03-02
| | | | | | | | To make the best use of existing code, I generalised the wrapper that currently does yuv420p10 to p010 to support any mixture of input and output sizes between 10 and 16 bits. This had the side effect of yielding a working code path for all yuv420p1x formats to p01x.

| * build: Add feature test macros for glibc 2.19+Diego Biurrun2017-07-10
| | | | | | | | | | | | | | glibc introduced _DEFAULT_SOURCE in version 2.19 to replace _BSD_SOURCE and _SVID_SOURCE, which were deprecated in version 2.20. Add _DEFAULT_SOURCE where the latter two are used to be forwards-compatible and avoid warnings about the use of deprecated definitions.
