ofp-actions: Correct pop MPLS ethtype as consistency test

Correct pop MPLS ethtype consistency check to verify that
the packet has an MPLS ethtype before the pop action rather than after:
an MPLS ethtype is a pre-condition but not a post-condition of pop MPLS.

With this change the consistency check in ofpact_check__()
becomes consistent with that in ofpact_from_nxast().

This was found using Ryu tests via the new make check-ryu target.
It allows all of the "POP_MPLS"[1] tests to pass where they previously
failed.

ofproto: Remove 'force-miss-model' configuration.

This configuration item was introduced to assist testing of upcall
handling behaviour with and without facets. Facets were removed in
commit e79a6c833e0d7237, so this patch removes the configuration item.

ovs-vsctl: reconnect to the database if connection was dropped

If ovs-vsctl has to wait for ovs-vswitchd to reconfigure itself
according to the new database, then sometimes ovs-vsctl could
end up stuck in the event loop if OVSDB connection was dropped
while ovs-vsctl was still running.

This patch fixes this problem by letting ovs-vsctl to reconnect
to the OVSDB, if it has to wait cur_cfg field to be updated.

packets: Always set ethertype in push_mpls()

There are two different MPLS ethertypes, 0x8847 and 0x8848 and a push MPLS
action applied to an MPLS packet may cause the ethertype to change from one
to the other. To ensure that this happens update the ethertype in
push_mpls() regardless of if the packet is already MPLS or not.

Test based on a similar test by Joe Stringer.

netdev: Change netdev_class_rwlock to recursive mutex, for POSIX safety.

With glibc, rwlocks by default allow recursive read-locking even if a
thread is blocked waiting for the write-lock.  POSIX allows such attempts
to deadlock, and it appears that the libc used in NetBSD, at least, does
deadlock.  The netdev_class_rwlock is in fact acquired recursively in this
way, which is a bug.  This commit fixes the problem by switching to a
recursive mutex.  This allows for less parallelism, but according to an
existing comment that doesn't matter here anyway.
