tryimportone: use dirstateguard instead of beginparentchange/endparentchange
To fix the issue that the recent (in memory) dirstate isn't visible to
external process (e.g. "precommit" hook), a subsequent patch makes
"localrepository.commit()" invoke "dirstate.write()" in it.
This change will make "beginparentchange()" and "endparentchange()" on
dirstate in "cmdutil.tryimportone()" meaningless, because:
- "dirstate.write()" writes changed data into ".hg/dirstate", but
- aborting between "beginparentchange()" and "endparentchange()"
doesn't cause any restoring ".hg/dirstate"
it just discards changes in memory.
This patch uses "dirstateguard" instead of "beginparentchange()" and
"endparentchange()" in "cmdutil.tryimportone()" to restore
".hg/dirstate" during a failure even if "dirstate.write()" is executed
before a failure.
This patch uses "lockmod.release(dsguard)" instead of
"dsguard.release()", because processing may be aborted before
assignment to "dsguard" , and the "if dsguard" examination for safety is
redundant.
