[PATCH v1 01/22] docs: Documentation/*.txt: rename all ReST files to *.rst

[Mauro Carvalho Chehab <mchehab+samsung@xxxxxxxxxx>]

Those files are actually at ReST format. Ok, currently, they
don't belong to any place yet at the organized book series,
but we don't want patches to break them as ReST files. So,
rename them and add a :orphan: in order to shut up warning
messages like those:

...
    Documentation/svga.rst: WARNING: document isn't included in any toctree
    Documentation/switchtec.rst: WARNING: document isn't included in any toctree
...

Later patches will move them to a better place and remove the
:orphan: markup.

I had to remove the long list of maintainers got by
getpatch.pl, as it was too long. I opted to keep only the
mailing lists.
