Turn on FC-Tape by default in the isp(4) driver.
FC-Tape provides additional link level error recovery, and is highly recommended for tape devices. It will only be turned on for a given target if the target supports it.
Without this setting, we default to whatever FC-Tape setting is in NVRAM on the card.
This can be overridden by setting the following loader tunable, for example for isp0:
hint.isp.0.nofctape=1
sys/conf/options: Add a new kernel config option, ISP_FCTAPE_OFF, that defaults the FC-Tape configuration to off.
sys/dev/isp/isp_pci.c: If ISP_FCTAPE_OFF is defined, turn off FC-Tape. Otherwise, turn it on if the card supports it.
share/man/man4/isp.4: Add a description of FC-Tape to the isp(4) man page.
Add descriptions of the fctape and nofctape options, as well as the ISP_FCTAPE_OFF kernel configuration option.
Add the ispfw module and kernel drivers to the suggested configurations at the top of the man page so that users are less likely to leave it out. The driver works well with the included firmware, but may not work at all with whatever firmware the user has flashed on their card.

In order to get vt(4) a bit closer to the feature set provided by sc(4), implement options TERMINAL_{KERN,NORM}_ATTR. These are aliased to SC_{KERNEL_CONS,NORM}_ATTR and like these latter, allow to change the default colors of normal and kernel text respectively. Note on the naming: Although affecting the output of vt(4), technically kern/subr_terminal.c is primarily concerned with changing default colors so it would be inconsistent to term these options VT_{KERN,NORM}_ATTR. Actually, if the architecture and abstraction of terminal+teken+vt would be perfect, dev/vt/* wouldn't be touched by this commit at all.

Merge from project branch via main. Uninteresting commits are trimmed.
Refactor of /dev/random device. Main points include:
* Userland seeding is no longer used. This auto-seeds at boot time on PC/Desktop setups; this may need some tweeking and intelligence from those folks setting up embedded boxes, but the work is believed to be minimal.
* An entropy cache is written to /entropy (even during installation) and the kernel uses this at next boot.
* An entropy file written to /boot/entropy can be loaded by loader(8)
* Hardware sources such as rdrand are fed into Yarrow, and are no longer available raw.

This means we can't count on /var being present, so something will need to be done about harvesting /var/db/entropy/... .

Marginally improve the entropy pool hashing, making it a bit faster in the process.

Contains:
* Refactor the hardware RNG CPU instruction sources to feed into the software mixer. This is unfinished. The actual harvesting needs to be sorted out. Modified by me (see below).
* Remove 'frac' parameter from random_harvest(). This was never used and adds extra code for no good reason.
* Remove device write entropy harvesting. This provided a weak attack vector, was not very good at bootstrapping the device. To follow will be a replacement explicit reseed knob.
* Separate out all the RANDOM_PURE sources into separate harvest entities. This adds some secuity in the case where more than one is present.
* Review all the code and fix anything obviously messy or inconsistent. Address som review concerns while I'm here, like rename the pseudo-rng to 'dummy'.

1) example (partially humorous random_adaptor, that I call "EXAMPLE") * It's not meant to be used in a real system, it's there to show how the basics of how to create interfaces for random_adaptors. Perhaps it should belong in a manual page
2) Move probe.c's functionality in to random_adaptors.c * rename random_ident_hardware() to random_adaptor_choose()
3) Introduce a new way to choose (or select) random_adaptors via tunable "rngs_want" It's a list of comma separated names of adaptors, ordered by preferences. I.e.: rngs_want="yarrow,rdrand"
Such setting would cause yarrow to be preferred to rdrand. If neither of them are available (or registered), then system will default to something reasonable (currently yarrow). If yarrow is not present, then we fall back to the adaptor that's first on the list of registered adaptors.
4) Introduce a way where RNGs can play a role of entropy source. This is mostly useful for HW rngs.

MFC r282213:
Add kern.racct.enable tunable and RACCT_DISABLED config option. The point of this is to be able to add RACCT (with RACCT_DISABLED) to GENERIC, to avoid having to rebuild the kernel to use rctl(8).
MFC r282901:
Build GENERIC with RACCT/RCTL support by default. Note that it still needs to be enabled by adding "kern.racct.enable=1" to /boot/loader.conf.
Note those two are MFC-ed together, because the latter one changes the name of RACCT_DISABLED option to RACCT_DEFAULT_TO_DISABLED. Should have committed the renaming separately...

In order to get vt(4) a bit closer to the feature set provided by sc(4), implement options TERMINAL_{KERN,NORM}_ATTR. These are aliased to SC_{KERNEL_CONS,NORM}_ATTR and like these latter, allow to change the default colors of normal and kernel text respectively. Note on the naming: Although affecting the output of vt(4), technically kern/subr_terminal.c is primarily concerned with changing default colors so it would be inconsistent to term these options VT_{KERN,NORM}_ATTR. Actually, if the architecture and abstraction of terminal+teken+vt would be perfect, dev/vt/* wouldn't be touched by this commit at all.

Merge from project branch via main. Uninteresting commits are trimmed.
Refactor of /dev/random device. Main points include:
* Userland seeding is no longer used. This auto-seeds at boot time on PC/Desktop setups; this may need some tweeking and intelligence from those folks setting up embedded boxes, but the work is believed to be minimal.
* An entropy cache is written to /entropy (even during installation) and the kernel uses this at next boot.
* An entropy file written to /boot/entropy can be loaded by loader(8)
* Hardware sources such as rdrand are fed into Yarrow, and are no longer available raw.

Debugging. My attempt at EVENTHANDLER(multiuser) was a failure; use EVENTHANDLER(mountroot) instead.
This means we can't count on /var being present, so something will need to be done about harvesting /var/db/entropy/... .

Looking pretty good; this mostly works now. New code includes:

SNAPSHOT.
Simplify the malloc pools; We only need one for this device.
Simplify the harvest queue.
Marginally improve the entropy pool hashing, making it a bit faster in the process.
Connect up the hardware "live" source harvesting. This is simplistic for now, and will need to be made rate-adaptive.
All of the above passes a compile test but needs to be debugged.

Snapshot. This passes the build test, but has not yet been finished or debugged.
Contains:
* Refactor the hardware RNG CPU instruction sources to feed into the software mixer. This is unfinished. The actual harvesting needs to be sorted out. Modified by me (see below).
* Remove 'frac' parameter from random_harvest(). This was never used and adds extra code for no good reason.
* Remove device write entropy harvesting. This provided a weak attack vector, was not very good at bootstrapping the device. To follow will be a replacement explicit reseed knob.
* Separate out all the RANDOM_PURE sources into separate harvest entities. This adds some secuity in the case where more than one is present.
* Review all the code and fix anything obviously messy or inconsistent. Address som review concerns while I'm here, like rename the pseudo-rng to 'dummy'.
