pushkey: splits obsolete marker exchange into multiple keys
Obsolete markers are now exchanged in smaller pieces that fit in a http header.
This changes is done to avoid 400 bad request error when exchanging obsolete
puskey over http.
The last key pushed is always hold by the "dump0" key to ensure an easy place to
hook for people who need it.

mq may keep a reference to the repository so __del__ will not be
called and .hg/journal.dirstate will not be deleted:
$ hg ci -m foo
error: pretxncommit.nocommits hook failed: no commits allowed
transaction abort!

abort: no commits allowed
