All active fields in fsi are advisory/optional, so we shouldn't do
extra work to make them valid at all times, but instead we write to
the fsi too often (we still do), and we searched for a free cluster
for fsinxtfree too often.
This commit just removes the whole search and its results, so that we
write out our in-core copy of fsinxtfree instead of writing a "fixed"
copy and clobbering our in-core copy. This saves fixing 3 bugs:
- off-by-1 error for the end of the search, resulting in fsinxtfree
not actually being adjusted iff only the last cluster is free.
- missing adjustment when no clusters are free.
- off-by-many error for the start of the search. Starting the search
at 0 instead of at (the in-core copy of) fsinxtfree did more than
defeat the reasons for existence of fsinxtfree. fsinxtfree exists
mainly to avoid having to start at 0 for just the first search per
mount, but has the side effect of reducing bias towards allocating
near cluster 0. The bias would normally only be generated by the
first search per mount (if fsinxtfree is not supported), but since
we also adjusted the in-core copy of fsinxtfree here, we were doing
extra work to maximize the bias.

- Improve load long-term load balancer by always IPIing exactly once.
Previously the delay after rebalancing could cause problems with
uneven workloads.
- Allow nice to have a linear effect on the interactivity score. This
allows negatively niced programs to stay interactive longer. It may be
useful with very expensive Xorg servers under high loads. In general
it should not be necessary to alter the nice level to improve interactive
response. We may also want to consider never allowing positively niced
processes to become interactive at all.
- Initialize ccpu to 0 rather than 0.0. The decimal point was leftover
from when the code was copied from 4bsd. ccpu is 0 in ULE because ULE
only exports weighted cpu values.

This allows to use numbers in human-readable form in many geom(8)
utilities. Such a simple change and makes live so much nicer.
Some examples:
gstripe label -s 16k
gmirror label -s 4k
gnop create -o 1g -s 128m -S 2k
gjournal label -s 2g
geli label -i 128k -s 4k

changes the units from seconds to the value of 'ticks' when swapped
in/out. ULE does not have a periodic timer that scans all threads in
the system and as such maintaining a per-second counter is difficult.
- Change computations requiring the unit in seconds to subtract ticks
and divide by hz. This does make the wraparound condition hz times
more frequent but this is still in the range of several months to
years and the adverse effects are minimal.

Some ports will install with compressed manpages. man handles
this by looking for the .gz version of a man source file.
It is also common to include other files with the .so
directive where commands or functions share a man page.
Traditionally ports have had to handle this by either not
compressing the manpages, or using the _MLINKS macro in the
port makefile to create symlinks to the actual source file,
rather than using .so versions. Notably, the current version
of Xorg port breaks. See ports/113096 and ports/115845.

In particular:
- smp_tlb_mtx is no longer used, so it is axed.
- smp rendezvous lock isn't really a leaf spin-mutex. Its bad placement in
the table, however, has been the source of a false positive LOR reporting
with the dt_lock. However, smp rendezvous lock would have had sched_lock
there for older lock, so it wasn't still a leaf lock.
- allpmaps is only used in ia32 architecture, so it is inserted in the
appropriate stub.
Addictionally:
- kse_zombie_lock is no longer present, so its definition is axed out.
- zombie_lock doesn't need to have an exported symbol, so just let's it be
declared as static.
