run-tests: fix race condition
Before this patch, it was possible for run-tests to crash on a race condition.
The race condition happens in the following case:
- the last test finishes and calls: done.put(None)
- the context switches to the main thread that clears the channels list
- the context switches to the last test mentioned above, it tries to access
channels[channel] and crashes
This happened to me while running run-tests.
This patch fixes the issue by clearing the channel before considering that the
test is done.
transaction: abort transaction during hook exception
The new transaction context did not handle the case where an exception during
close should still call release. This cause pretxnclose hooks that failed to
cause the transaction to fail without aborting, thus requiring a hg recover.
I've added a test.

changegroup: cg3 has two empty groups *after* manifests
changegroup.getchunks() determines the end of the stream by looking
for an empty chunk group (two consecutive empty chunks). It ignores
empty groups in the first two groups. Changegroup 3 introduced an
empty chunk between the manifests and the files, which confuses
getchunks(). Since it comes after the first two, getchunks() will stop
there.
Fix by rewriting getchunks so it first counts two groups (empty or
not) and then keeps antostarts counting empty groups. With this counting,
changegroup 1 and 2 have exactly one empty group after the first two
groups, while changegroup 3 has two (one for directories and one for
files).
It's a little hard to test this at this point, but I have verified
that this patch fixes narrowhg (which was broken before this
patch). Also, future patches will fix "hg strip" with treemanifests,
and once that's done, getchunks() will be tested through tests of "hg
strip".

Catching aborts might not be pretty but it works and is a small change.
