holding SOCKBUF_LOCK() isn't sufficient to guarantee that there is
no upcall in progress, since SOCKBUF_LOCK() is released/re-acquired
in the upcall. An upcall reference counter was added to the upcall
structure that is incremented at the beginning of the upcall and
decremented at the end of the upcall. As such, a reference count == 0
when holding the SOCKBUF_LOCK() guarantees there is no upcall in
progress. Add a function that is called just after soupcall_clear(),
which waits until the reference count == 0.
Also, move the mtx_destroy() down to after soupcall_clear(), so that
the mutex is not destroyed before upcalls are done.

Add a flag so that soupcall_clear() is only called once to cancel
an upcall.
Move the test for xprt_registered in the upcall down to after the
mtx_lock() of the pool mutex, to catch the case where it is
unregistered while the upcall is waiting for the mutex.
Also, move the mtx_destroy() of the pool mutex to after SVC_RELEASE(),
so that it isn't destroyed before the upcalls are disabled.

ICIDU NI-707503 which is donated by Nick Hibma (great thanks!). Though
it has a MAXIM RF (0x8) there's some success reports with using GCT RF
(0x9) codes and it worked well for ICIDU NI-707503 too. So codes for
MAXIM and GCT RFs are integrated.
Before this commit, if I rememeber correctly, MAXIM RF is never tested
that it seems it's a first report working with FreeBSD.
characteristics force the stations to re-associate so protocol state

modules are loaded by avoiding mbuf label lookups when policies aren't
loaded, pushing further socket locking into MAC policy modules, and
avoiding locking MAC ifnet locks when no policies are loaded:
- Check mac_policies_count before looking for mbuf MAC label m_tags in MAC
Framework entry points. We will still pay label lookup costs if MAC
policies are present but don't require labels (typically a single mbuf
header field read, but perhaps further indirection if IPSEC or other
m_tag consumers are in use).
- Further push socket locking for socket-related access control checks and
events into MAC policies from the MAC Framework, so that sockets are
only locked if a policy specifically requires a lock to protect a label.
This resolves lock order issues during sonewconn() and also in local
domain socket cross-connect where multiple socket locks could not be
held at once for the purposes of propagatig MAC labels across multiple
sockets. Eliminate mac_policy_count check in some entry points where it
no longer avoids locking.
- Add mac_policy_count checking in some entry points relating to network
interfaces that otherwise lock a global MAC ifnet lock used to protect
ifnet labels.

Minimize differencies between our ext2fs headers and relevant Linux
versions by using EXT2_SB macro to access the superblock fields. Most
of the differencies in access to these fields are now hidden inside
this macro.
- Rename the s_db_per_group field of ext2fs_sb_info to s_gdb_count
to reflect the similar change in Linux headers. New name also seem
to be more appropriate for this field.
- Use proper types for s_first_inode and s_inode_size in-core superblock
fields. Now they reflec types used in the on-disk superblock version.
- Add support for older filesystem revisions that doesn't have proper
s_first_ino and s_inode_size fields in the on-disk superblock. In these
cases predefined values for these fields are used.
- Add simple sanity checks for s_first_inode and s_inode_size correctness.

deleted when the system is low on memory. This ought to allow an increase to
vfs.ufs.dirhash_maxmem on machines that have lots of memory, without
degrading performance by having too much memory reserved for dirhash when
other things need it. The default value for dirhash_maxmem is being kept at
2MB for now, though.
This work was mostly done during the 2008 Google Summer of Code.
