wireprotov2: add bookmarks to "changesetdata" command
Like we did for phases, we want to emit bookmarks data attached
to each changeset.
The approach here is very similar to phases: we emit bookmarks
data inline with requested revision data. But we emit
records for nodes that weren't requested as well so consumers have
access to the full set of defined bookmarks.

#testcases lfsremote-on lfsremote-off
#require serve no-reposimplestore no-chg
This test splits `hg serve` with and without using the extension into separate
tests cases. The tests are broken down as follows, where "LFS"/"No-LFS"
indicates whether or not there are commits that use an LFS file, and "D"/"E"
indicates whether or not the extension is loaded. The "X" cases are not tested
individually, because the lfs requirement causes the process to bail early if
the extension is disabled.

Skip the experimental.changegroup3=True config. Failure to agree on this comes
first, and causes a "ValueError: no common changegroup version" or "abort:
HTTP Error 500: Internal Server Error", if the extension is only loaded on one
side. If that *is* enabled, the subsequent failure is "abort: missing processor
for flag '0x2000'!" if the extension is only loaded on one side (possibly also
masked by the Internal Server Error message).

This trivial repo will force commandserver to load the extension, but not call
reposetup() on another repo actually being operated on. This gives coverage
that wrapper functions are not assuming reposetup() was called.
