[yocto] Bitbake bash completion

[Sergio Prado]

Hello all,

I have just written a bitbake bash completion script so it could make
my life easier when trying to discover a recipe name and bake it.

https://github.com/sergioprado/bitbake-bash-completion

It should complete all commands (bitbake 1.22.0), recipes and tasks.

When running for the first time, it will execute "bitbake -e" to get
the BBPATH variable and save it in a hidden file. It will use this
file on subsequent executions.

Feel free to try it and let me know if you find any bug or have
suggestions on how to improve it.

Thanks,

Sergio Prado
