Ramiro Polla a1bfaa0e78 swscale/aarch64: introduce tool to enumerate sws_ops for NEON backend 
The NEON sws_ops backend will use a build-time code generator for the
various operation functions it needs to implement. This build time code
generator (ops_asmgen) will need a list of the operations that must be
implemented. This commit adds a tool (sws_ops_aarch64) that generates
such a list (ops_entries.c).

The list is generated by iterating over all possible conversion
combinations and collecting the parameters for each NEON assembly
function that has to be implemented, defined by an unique set of
parameters derived from SwsOp. Whenever swscale evolves, with improved
optimization passes, new pixel formats, or improvements to the backend
itself, this file (ops_entries.c) should be regenerated by running:
    $ make sws_ops_entries_aarch64
