Code review: reformat comments.
Add comments to fiber.h.
Use tnt_FiberCancelException solely to cancel fibers.
Fix alignment of fiber_server.
Use newer confetti.

Reverse the try/finally wrapping of some fiber functions
as unnecessary.

Tweak my previous patch for proctitle to be a bit
more robust to the path length.

Start pruning Tarantool wiki on github, and add documentation
on Tarantool process title to the user guide, since
it is present on the wiki but not in the user guide.

While at it, make the process title more lookalike on Linux
and FreeBSD, and rename some of the (what looks to me as) unclear
process titles.
The documentation reflects the new naming scheme already.

Move Ruby connector to its new destination (connector/).

Extend language-reference.xml.
Minor edits of salloc.m.

Document memcached options. Tweak doc/sql.txt.

Add sql.txt, describing the supported SQL grammar,
to which the user guide refers.

Add more content to the user guide (language reference, memcached support).

Learn how to use olinking correctly.
Add errcode.xml - the list of all error codes.
While at it, add markers to errcode.h signalling
that whenever it is changed, errcode.xml also needs a change.
Get rid of ERR_CODE_UNKNOWN_ERROR - it has no raison d'être.

Tweak the docbook to html XSL rules, in particular
table of contents generation.

Explain how to configure a namespace.
Tweak some error messages on the way.

Adjust signature of tbuf_ltrim, add comments,
replace a check with an assert.

tbuf: tbuf_ltrim function was added.
admin: admin_dispatch routine was fixed. fiber read buff managment was changed
       from peek to trim.

Update test results.

Review fixes: the original patch is fine,
but since we use strlen() for help, let's use strlen() for
unknown_command too.

Fix the test runner after rename of --daemonize to --background.
Add comments to README.

Implement slave-to-master and vise versa propagation through
'configuration reload' admin command.

Update comments in the configuration templates
(spelling errors).
