chgserver: change random state after fork

Before this patch, extensions expecting a different random state per command
will break since the chg request handler will inherit a same random state
from the parent daemon process.

This patch addresses the issue by calling random.seed() after fork.

Test that qpush cleans things up if it doesn't complete

  $ echo "[extensions]" >> $HGRCPATH
  $ echo "mq=" >> $HGRCPATH
  $ hg init repo
  $ cd repo
  $ echo foo > foo
  $ hg ci -Am 'add foo'
  adding foo
  $ touch untracked-file
  $ echo 'syntax: glob' > .hgignore
  $ echo '.hgignore' >> .hgignore
  $ hg qinit

test qpush on empty series

  $ hg qpush
  no patches in series
  $ hg qnew patch1
  $ echo >> foo
  $ hg qrefresh -m 'patch 1'
  $ hg qnew patch2
  $ echo bar > bar
  $ hg add bar

now we expect the push to fail, but it should NOT complain about patch1

preparing qpush of missing patch with no patch applied

qpush should fail the same way as below
