This change is related to the bitmanip draft version 0.94. It's needed
as in draft version 0.93 as well as in version 1.00 sbext from Zbs

Restructure the existing documentation to group the content by intended
audience. This produces four sections:
* An introduction section, relevant to "newcomers" to Ibex.
* An user guide, intended for hardware designers (integrators) and
software developers who want to integrate Ibex, and develop software
for it.
* A reference guide, which provides background information on the
design. This section is essential when working on Ibex, and also
documents our design decisions.
* A developer guide aimed at people modifying Ibex itself. It consists
mostly of process and tool documentation: how to run the verification
after a code change, how to use GitHub, etc.
This commit is large, but text is mostly unchanged. A couple of
introductions and tables of content were added, but no significant
changes to the text have been made. These will be done in follow-ups.
