mq: update subrepos when applying / unapplying patches that change .hgsubstate
Up until now applying or unapplying a patch that modified .hgsubstate would not
work as expected because it would not update the subrepos according to the
.hgsubstate change. This made it very easy to lose subrepo changes when using
mq.
This revision also changes the test-mq-subrepo test so that on the qpop / qpush
tests. We no longer use the debugsub command to check the state of the subrepos
after the qpop and qpush operations. Instead we directly run the id command on
the subrepos that we want to check. The reason is that using the debugsub
command is misleading because it does not really check the state of the subrepos
on the working directory (it just returns what the change that is specified on a
given revision). Because of this the tests did not detect the problem that this
revision fixes (i.e. that applying a patch did not update the subrepos to the
corresponding revisions).
