Migrating patches from 4.3 to 5.0

[lfryc]

I have did proof of concept of migrating patches from 4.3 branch to 5.0, since it appeared to be untrivial, because of:

• merged repository subtrees
• running dos2unix over all files
• renamed source files

At the end, I have ended up with set of scripts which can be used to migrate a patches in batches per repository:

Even though the procedure involves several manual interventions, it actually took me just 1,5hr to invent it

and "fix" Core and Components 4.3 patches to apply cleanly on 5.0.

The result is quite satisfying:

https://github.com/richfaces/richfaces5/commits/applying-patches-upto-4.3.1.Final

I still need to convert further commits (post 4.3.1.Final - basically fundamental test setup improvements),

but I think this migration procedure is a viable solution.

Nice job Lukas!  We should put those scripts in the RichFaces 5 repository (with a README.md) to enable easy re-use.

I have put those instructions into RichFaces 4 repository:
