[FFmpeg-user] FFmpeg for Android

[Срђан Обућина]

Makefiles are updated, and they bring some new features:

- On-the-fly library configuration. FFmpeg will be configured on-the-fly,
during Android building process, in accordance to the selected product, cpu
architecture, cpu architecture variant, and fine tuning cpu parameters.
 -Configuration driven building. No need to manually add filenames to the
makefiles, or hack through the library in order to get the build you want.
- Per product configuration. Every TARGET_PRODUCT will have its own
configuration.
- Builds all libraries and tools, except ffplay.
- Builds both shared and static libraries.
