merge with crew-stable

test-serve: wait before killing to always hide the "killed!" message. Without the sleeps slower systems never display never display "killed!" while faster systems sometimes or nearly always display it.

Mention 'hg update' to switch branches in help for branch and branches.

Clarify help for hg status and make it consistent.

profile: expand PID in output file name

convert: allow synthetic history to be spliced in. Useful for recreating history in the face of SVN lossage.

profiling: allow CGI and FastCGI to be profiled

update copyright notice in version output

hgweb: explicit response status

updating lsprof.py from remote repository

highlight: update according to latest hgweb_mod changes Also move encoding workaround completely into non binary condition.

Fixed typo: Gnerating -> Generating

added \r for progress counting in churn extension

update the branch cache at the end of addchangegroup This should avoid a bad performance problem when the branch cache is not up-to-date, and hgweb can't write an updated version because it lacks permissions.

qpop/qrefresh: update self.applied before calling strip This will be important for the next patch, which may end up using this variable during an addchangegroup caused by strip.

hg import: write the dirstate after every commit This allows the transaction system to backup the correct file, so that a future rollback can do the right thing. This should fix issue963.

localrepo._tag: add a seek before writing the new tag Some systems require a seek (or flush) between read and write operations on the same file object. This should fix issue838.

convert: use 'unknown' and '0 0' if commit author or date weren't specified Closes issue873.

httprepo: use separate handlers for HTTP and HTTPS This is needed to keep the code in keepalive.py from sharing the same connection between HTTP and HTTPS. 52ce0d6bc375 explains why we were using a single handler. This should fix issue892.

move __del__ from httprepository to basehttphandler This should prevent the next patch from reopening an issue fixed by 0d94e4a3ddb4.

mq: don't allow patches with some reserved names The current list of reserved names includes only mq control files. Also, reserve names starting with ".hg" (to avoid troubles with e.g. .hgignore and .hgtags), and with ".mq" (to allow future extensions). This should fix issue841.

mq: pop/refresh: avoid losing revisions not managed by mq We already disallow committing on top of an mq revision exactly to avoid losing this new revision during a qpop/qrefresh, so this can be seen as an additional safety check. If this is not enough to fix issue844, it should at least prevent it from happening.

mqrepo: don't abort if the status file has an unknown node

sshrepo: be more careful while reading data This should avoid some tracebacks when the server sends some garbage.

fix markup of templates/{,old/}header.tmpl

templates: move filters to their own module This eliminates just about all Mercurial dependencies in templater.py

templater: move email function to util

templater: remove node import

patchbomb: undo backout and fix bugs in the earlier patch

added an entry about the prefix option inside the hgrc man page
