pfind(9): follow-up fixes and improvements
(Found on a branch from a year ago.)
- Adjust NAMEs
- MLINKS: add pfind_any.9, pfind_any_locked.9; remove old zpfind.9
- Reword the description of pfind_any() so that it doesn't imply only
zombie processes are returned
- Fix a comma
- Use .Dv for the macro PRS_ZOMBIE
- Move the (logically separate) final statement to a new paragraph
- .Xr to pget(9)

www/py-aiobreaker: Add new port
aiobreaker is a Python implementation of the Circuit Breaker pattern,
described in Michael T. Nygard's book Release It!_.
Circuit breakers exist to allow one subsystem to fail without destroying
the entire system. This is done by wrapping dangerous operations
(typically integration points) with a component that can circumvent
calls when the system is not healthy.
e1000: Don't enable ASPM L1 without L0s
Reporter noted packet loss with 82583. NVM is down level. The
errata docs mention disabling this, which should be the firmware
default, so I am not sure why we were enabling this bit. Linux and
OpenBSD have the same issue, while NetBSD got it right.

e1000: Bump 82574/82583 PBA to 32K
The reporter contacted me with packet loss and throughput fluctuations
on a low power machine (Intel J1900) that got worse with the recent AIM
algorithm in FreeBSD 14.2+.
32K RX PBA matches Linux default. Add a conditional path since we don't
otherwise do a fixup for jumbo frames to retain space for two frames in
Tx.
With this change and an additional errata change, the throughput meets
line rate for the reporter.

pmc: add alderlake model
The commit 601925180df4 added the models 6-B7, 6-BA, 6-BF to libpmc, but
they must also be added to the hwpmc module to allow pmc to work on
those CPUs.

cam: Reduce overly long timeout values for initial device probing
Currently, we have very long timeouts for the initial probing
commands. However, these are not appropriate for modern (post 2010) SCSI
disks. Sandards since SPC3 state that these commands should not wait for
media access. Since we retry them several times during the initial bus
scan, these delays can delay the boot by minutes (5 minutes per errant
disk in our expereince). These delays don't help and only hurt, so
reduce the TESTUNITREADY, INQUIRY and MODESENSE commands (during the
initial probe). Provide sysctl/tuneables to change the time for these
and also the REPORTLUNS commands for people that might need to adjust
them for devices that violate this belief but none-the-less work with
longer timeouts.
kern.cam.tur_timeout (default was 60s, now 1s)
kern.cam.inquiry_timeout (default was 60s, now 1s)
kern.cam.reportluns_timeout (default is 60s)
kern.cam.modesense_timeout (default was 60s, now 1s)
This can be partially merged: the sysctls can, but the new defaults likely
shouldn't.
