Unwire with map lock held
This is an updated version of uvm_map.c r1.283 "Unwire with map lock held".
The previous version introduced a use-after-free by not unlocking vm_map
locks in uvm_map_teardown(), resulting in dangling references on the
reaper's lock list (thanks visa!).
Lock and unlock the map in around uvm_map_teardown() instead.
This code path holds the last reference, hence the lock isn't strictly
needed except for satisfying upcoming locking assertions.
Tested on amd64, arm64, i386, macppc, octeon, sparc64.
This time also with WITNESS enabled (except on sparc64 which builds but does
not boot with WITNESS; this is a known issue).

update sbchecklowmem() to better detect actual mbuf memory usage.
previously sbchecklowmem() (and sonewconn()) would look at the mbuf
and mbuf cluster pools to see if they were approaching their hard
limits. based on how many mbufs/clusters were allocated against the
limits, socket operations would start to fail with ENOBUFS until
utilisation went down.
mbufs and clusters have changed a lot since then though. there are
now many mbuf cluster pools, not just one for 2k clusters. because
of this the mbuf layer now limits the amount of memory all the mbuf
pools can allocate backend pages from rather than limit the individual
pools. this means sbchecklowmem() ends up looking at the default
pool hard limit, which is UINT_MAX, which in turn means means
sbchecklowmem() probably never applies backpressure. this is made
worse on multiprocessor systems where per cpu caches of mbuf and
cluster pool items are enabled because the number of in use pool
items is distorted by the cpu caches.
this switches sbchecklowmem to looking at the page allocations made
by all the pools instead. the big benefit of this is that the page
allocations are much more representative of the overall mbuf memory
usage in the system. the downside is is that the backend page
allocation accounting does not see idle memory held by pools. pools
cannot release partially free pages to the page backend (obviously),
and pools cache idle items to avoid thrashing on the backend page
allocator. this means the page allocation level is higher than the
memory used by actual in-flight mbufs.
however, this can also be a benefit. the backend page allocation is a
kind of smoothed out "trend" line. mbuf utilisation over short periods
can be extremely bursty because of things like rx ring dequeue and fill
cycles, or large socket sends. if you're trying to grow socket
buffers while these things are happening, luck becomes an important
factor in whether it will work or not. because pools cache idle items,
the backend page utilisation better represents the overall trend
of activity in the system and will give more consistent behaviour here.
this diff is deliberately simple. we're basically going from "no
limits" to "some sort of limit" for sockets again, so keeping the
code simple means it should be easy to understand and tweak in the
future.

tr(1): rename lookup tables
The lookup tables in tr(1) are called "string1" and "string2". This is
misleading:
- They aren't C strings, they are lookup tables.
- The names "string1" and "string2" don't hint at what their contents
actually mean. The meaning of a given table changes with tr(1)'s
operating mode. There are five different modes.
It would be considerably easier to see what is happening at a glance
if the tables were named for their corresponding byte transformation.
So instead of two tables named "string1" and "string2" we'll have
three tables named "delete", "squeeze", and "translate". In addition,
the "string" passed to the setup() function will be called a "table".
With this patch the code in main() is way easier to understand.
Hopefully this makes subsequent patches easier to review.

Do not verify the cert or CA for a relay using opportunistic TLS.
If a relay is not explicitly configured to use TLS but the remote
side supports STARTTLS, we will try to use it. However, in this
case we should not verify the cert or CA (which may be self-signed).
This restores the relay behavior before the switch to libtls was made.
There is no change if the relay is explicitly configured to use TLS.

look(1): use a stricter pledge(2) in lieu of unveil(2)
We're only reading one file here, so unveil(2) is overkill. We can
achieve the same effect with just pledge(2):
- Start with an initial pledge(2) of "stdio rpath" at the top of main().
We know we need to read a file at this point but don't yet know which
one.
- Drop the pledge(2) down to "stdio" after we open(2) and fstat(2) the
chosen file.
- Dropping "rpath" obviates unveil(2).

Update Devel::PPPort in base from version 3.57 to 3.64. Our clang
13.0.0 produces thousands of -Wcompound-token-split-by-macro warnings
wir older ppport.h header files. They are especially frequent in
the ports tree. After this update we can use perl -MDevel::PPPort
-e'Devel::PPPort::WriteFile' to regenerate the ppport.h files. Then
we have a version that is recent enough to build all ports and does
not spit out tons of warnings.

Only show the 'not enough inodes' warning if the filesystem reports more
than zero free inodes. btrfs always reports zero inodes, so on linux
distros like fedora, users will always see the not enough space warning,
which it is a bit ugly.

Assert vm map locks
Introduce vm_map_assert_{wrlock,rdlock,anylock,unlocked}() in rwlock(9)
fashion and back up function comments about locking assumptions with proper
assertions.
Also add new comments/assertions based on code analysis and sync with
NetBSD as much as possible.
vm_map_lock() and vm_map_lock_read() are used for exclusive and shared
access respectively; currently no code path is purely protected by
vm_map_lock_read() alone, i.e. functions called with a read lock held by the
callee are also called with a write lock elsewhere.
Thus only vm_map_assert_{wrlock,anylock}() are used as of now.
This should help with unlocking UVM related syscalls

Unwire with map lock held
uvm_unmap_remove() effectively requires its caller to lock the vm map.
Even though uvm_map_teardown() is only called after a map's last reference
is dropped and is thus safe from other threads accessing the map, grab the
map's lock in uvm_map_teardown() to satify upcoming lock assertions in
uvm_unmap_remove().

If running with ASAN, mark test_with{,out}_bzero() with the
no_sanitize_address attribute. ASAN doesn't seem to be able
to understand these lowlevel gymnastics with sigaltstack()
and segfaults in __intercept_memem().
This allows LibreSSL and other portable projects that use this
test run tests with ASAN enabled.

Paraphrasing millert: it's a little ugly but it's only a regress.
