Create a documentation providing a background and explanation around the
operation of the Multi-Queue Block IO Queueing Mechanism (blk-mq).
The reference for writing this documentation was the source code and
"Linux Block IO: Introducing Multi-queue SSD Access on Multi-core
Systems", by Axboe et al.

The blk-crypto framework adds support for inline encryption. There are
numerous changes throughout the storage stack. This patch documents the
main design choices in the block layer, the API presented to users of
the block layer (like fscrypt or layered devices) and the API presented
to drivers for adding support for inline encryption.

Those are subsystem docs, with a mix of kABI and user-faced
docs. While they're not split, keep the dirs where they are,
adding just a pointer to the main index.

Rename the block documentation files to ReST, add an
index for them and adjust in order to produce a nice html
output via the Sphinx build system.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.
