mq: report correct numbers for changing "number of guarded, applied patches"

Before this patch, "hg qselect" may report incorrect numbers for
"number of guarded, applied patches has changed", because it examines
"pushable" of patches by the index not in "the series" but in "applied
patches", even though "mq.pushable()" expects the former.

To report correct numbers for changing "number of guarded, applied
patches", this patch uses the name of applied patch to examine
pushable-ness of it.

This patch also changes the result of existing "hg qselect" tests,
because they doesn't change pushable-ness of already applied patches.

This patch assumes that "hg qselect" focuses on changing pushable-ness
only of already applied patches, because:

  - the report message uses not "previous" (in the series) but
    "applied"

  - the logic to pop patches for --pop/--reapply examines
    pushable-ness only of already applied ones (in fact, there are
    some incorrect code paths)

Corrupt an hg repo with a pull started during an aborted commit
Create two repos, so that one of them can pull from the other one.

  $ hg init source
  $ cd source
  $ touch foo
  $ hg add foo
  $ hg ci -m 'add foo'
  $ hg clone . ../corrupted
  updating to branch default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo >> foo
  $ hg ci -m 'change foo'

Add a hook to wait 5 seconds and then abort the commit

  $ cd ../corrupted
  $ echo "[hooks]" >> .hg/hgrc
  $ echo "pretxncommit = sh -c 'sleep 5; exit 1'" >> .hg/hgrc

start a commit...

  $ touch bar
  $ hg add bar
  $ hg ci -m 'add bar' &

... and start a pull while the commit is still running

  $ sleep 1
  $ hg pull ../source 2>/dev/null
  pulling from ../source
  transaction abort!
  rollback completed
