docs: rSTify the "TrivialPatches" wiki

The original wiki is here[1].  I converted by copying the wiki source
into a .wiki file and convert to rST using `pandoc`:

        $ pandoc -f Mediawiki -t rst trivial-patches.wiki -o trivial-patches.rst

Update the active maintainer names (and drop Michael Tokarev's inactive
repo) to reflect current reality.

+Trivial Patches
+===============
+
+Overview
+--------
+
+Trivial patches that change just a few lines of code sometimes languish
+on the mailing list even though they require only a small amount of
+review. This is often the case for patches that do not fall under an
+actively maintained subsystem and therefore fall through the cracks.
+
+The trivial patches team take on the task of reviewing and building pull
+requests for patches that:
+
+- Do not fall under an actively maintained subsystem.
+- Are single patches or short series (max 2-4 patches).
+- Only touch a few lines of code.
+
+**You should hint that your patch is a candidate by CCing
+qemu-trivial@nongnu.org.**
+
+Repositories
+------------
+
+Since the trivial patch team rotates maintainership there is only one
+active repository at a time:
+
+- git://github.com/vivier/qemu.git trivial-patches - `browse <https://github.com/vivier/qemu/tree/trivial-patches>`__
+
+Workflow
+--------
+
+The trivial patches team rotates the duty of collecting trivial patches
+amongst its members. A team member's job is to:
+
+1. Identify trivial patches on the development mailing list.
+2. Review trivial patches, merge them into a git tree, and reply to state
+   that the patch is queued.
+3. Send pull requests to the development mailing list once a week.
+
+A single team member can be on duty as long as they like. The suggested
+time is 1 week before handing off to the next member.
+
+Team
+----
+
+If you would like to join the trivial patches team, contact Laurent
+Vivier. The current team includes:
