- reduce cpu usage by as much as 25% (40% -> 30) by doing txq reclaim more efficiently
- use mtx_trylock when trying to grab the lock to avoid spinning during long encap loop
- add per-txq reclaim task
- if mbufs were successfully re-claimed try another pass
- track txq overruns with sysctl

Implement this in a naive way. Reports from the field show this makes
the driver functional with some locking issues, as opposed to an

With the in_mcast.c code, if an interface for an IPv4 multicast join was
not specified, and a route did not exist for the specified group in the
unicast forwarding tables, the join would be rejected with the error
EADDRNOTAVAIL.
This change restores the old behaviour whereby if no interface is specified,
and no route exists for the group destination, the IPv4 address list is
walked to find a non-loopback, multicast-capable interface to satisfy
the join request.
This should resolve problems with starting multicast services during
system boot or when a default forwarding entry does not exist.

vm_fault_additional_pages() that was introduced in revision 1.47. Then
as now, it is unnecessary because dev_pager_haspage() returns zero for
both the number of pages to read ahead and read behind, producing the
same exact behavior by vm_fault_additional_pages() as the special case
handling.

- Plug memory leak.
- Respect underlying vnode's properties rather than assuming that
the user want root:wheel + 0755. Useful for using tmpfs(5) for
/tmp.
- Use roundup2 and howmany macros instead of rolling our own version.
- Try to fix fsx -W -R foo case.
- Instead of blindly zeroing a page, determine whether we need a pagein
order to prevent data corruption.
- Fix several bugs reported by Coverity.

- When a LDT entry changes, the old one is freed while it is still
referenced by gdt and ldtr. This can lead to disruptive behaviours in
particular on SMP machines.
- When a LDT entry changes, it is assumed that the only one entity sharing
the same LDT are threads in the same proc. It doesn't take in account
edge cases where two processes share the same VM (rfork'ed ones, for
example).
This patch addresses these two problems and addictionally it fixes the
usage of refcount switching back it to the old manually-grown refcount
(since in this case would be faster).

whether we should ignore case, determine the flag by calling
compile_flags() first. Also, make sure that we obtain an
initialized cmd->u.s buffer before processing further. We
may want to refine this solution later, but for now, make

- Adjust lock_profiling stubs semantic in the hard functions in order to be
more accurate and trustable
- Disable shared paths for lock_profiling. Actually, lock_profiling has a
subtle race which makes results caming from shared paths not completely
trustable. A macro stub (LOCK_PROFILING_SHARED) can be actually used for
re-enabling this paths, but is currently intended for developing use only.
- Use homogeneous names for automatic variables in hard functions regarding
lock_profiling
- Style fixes
- Add a CTASSERT for some flags building
