commandserver: add IPC channel to teach repository path on command finished
The idea is to load recently-used repositories first in the master process,
and fork(). The forked worker can reuse a warm repository if it's preloaded.
There are a couple of ways of in-memory repository caching. They have pros
and cons:
a. "preload by master"
pros: can use a single cache dict, maximizing cache hit rate
cons: need to reload a repo in master process (because worker process
dies per command)
b. "prefork"
pros: can cache a repo without reloading (as worker processes persist)
cons: lower cache hit rate since each worker has to maintain its own cache
c. "shared memory" (or separate key-value store server)
pros: no need to reload a repo in master process, ideally
cons: need to serialize objects to sharable form
Since my primary goal is to get rid of the cost of loading obsstore without
massive rewrites, (c) doesn't work. (b) isn't ideal since it would require
much more SDRAMs than (a). So I take (a).
The idea credits to Jun Wu.

upgrade: correct implementation of improvement.__ne__
The "not" operator binds more closely than "==":
>>> not False == False
False

extensions: use ui.log() interface to provide detailed loading information
The output format changes and the messages will be sent to stderr instead of
stdout, but I don't think that matters.

mq: implement log() on dummyui
Otherwise ui.log() in extensions.py would explode.

ui: install logger that sends debug.extensions messages to stderr
This will replace the custom log function introduced at d58958676b3c
"extensions: add detailed loading information."

blackbox: resurrect recursion guard
If I added ui.log() to hg.repository() function, test-merge-subrepos.t
exploded. The problem is that the blackbox may create new repository instance
while logging is active, and the created repository owns its new ui derived
from the baseui, not from the ui which is processing the active logging.
I tried to work around the issue in ui.log(), but that turned out to be not
easy. We shouldn't globally lock the ui.log() since there may be more than
one active repo/ui instances in threaded environment. We could store the
logging state in thread-local storage, but that seems unnecessarily complex.
So this patch reintroduces the _inlog flag to per-repository logger instances.

tests: filter out uninteresting log events
This helps adding more log()s without updating the tests.

context: error out if basefilectx.cmp() is called without self._filenode
The base implementation can't handle such cases because the filelog has no
knowledge about the working directory.
Loading self._filenode should have no extra cost since self.size() would
load it anyway.

context: collapse complex condition to see if filelog have to be compared
It's hard to read. I'd rather make the return statement duplicated.
