Add a new installation type to bsdinstall/zfsboot: BIOS+UEFI
Installs both pmbr+gptzfsboot as well as boot1.efifat in separate partitions
The resulting system can be booted with either UEFI or BIOS/CSM.
Preference is controlled by the user's firmware boot settings.
Summary:
PowerPC Book-E SMP is currently broken for unknown reasons. Pull in
Semihalf changes made c2012 for e500mc/e5500, which enables booting SMP.
This eliminates the shared software TLB1 table, replacing it with
tlb1_read_entry() function.
This does not yet support ePAPR SMP booting, and doesn't handle resetting CPUs
already released (ePAPR boot releases APs to a spin loop waiting on a specific
address). This will be addressed in the near future by using the MPIC to reset
the AP into our own alternate boot address.
This does include a change to the dpaa/dtsec(4) driver, to mark the portals as
CPU-private.
Test Plan:
Tested on Amiga X5000/20 (P5020). Boots, prints the following
messages:
Adding CPU 0, pir=0, awake=1
Waking up CPU 1 (dev=1)
Adding CPU 1, pir=20, awake=1
SMP: AP CPU #1 launched

A new implementation of the loader block cache
The block cache implementation in loader has proven to be almost useless, and in worst case even slowing down the disk reads due to insufficient cache size and extra memory copy.
Also the current cache implementation does not cache reads from CDs, or work with zfs built on top of multiple disks.
Instead of an LRU, this code uses a simple hash (O(1) read from cache), and instead of a single global cache, a separate cache per block device.
The cache also implements limited read-ahead to increase performance.
To simplify read ahead management, the read ahead will not wrap over bcache end, so in worst case, single block physical read will be performed to fill the last block in bcache.
Booting from a virtual CD over IPMI:
0ms latency, before: 27 second, after: 7 seconds
60ms latency, before: over 12 minutes, after: under 5 minutes.

libc: do not include <sys/types.h> where <sys/param.h> was already included
According to style(9):
> normally, include <sys/types.h> OR <sys/param.h>, but not both.
(<sys/param.h> already includes <sys/types.h> when LOCORE is not defined).
META_MODE: Disable during installworld and similar.
META_MODE may create cookies during staging of files to WORLDTMP that would
also prevent installation of the files to the final DESTDIR, since the cookie
already exists. This is not yet the case but will be soon. Prevent other
similar issues by disabling META_MODE for any top-level install targets.
Cause an error during 'make install' if trying to compile with CC.
This is limited to src-tree builds, meaning not extended to ports or other
out-of-tree builds.
This will help ensure that read-only OBJDIRS will be respected at install-time
by causing a more consistent failure for those who don't use a read-only
OBJDIR. It also will cause Jenkins to yell. This is a better solution than
trying to see CC=false as has been attempted and discussed before.
Of course this is only relevant for files generated by CC.
Disable this for META_MODE since it will detect the CFLAGS/command
change and force a rebuild.
Follow-up r297842: Rework header generation to fix always rebuilding.
This reworks the handling of common headers to just include the needed
logic rather than invoke MAKE. This avoids the problem listed in r297842
and avoids other dependency tracking issues.

Allow RT3350 CPU clock to be detected as part of RT3050/RT3052 detection
OpenWRT's dts files treat RT3050/RT3052/RT3350 within the same SoC dtsi
file, so we need to distinguish between the three dynamically, mainly
because the bit we use to determine the clock speed on RT3050/RT3052
can actually be floating on RT3350 and RT3350 is always at 320MHz.

[net80211] put in a comment about the not-quite-correctness of A-MPDU parameters.
Although we correctly (now!) calculate the right A-MPDU parameters, the
ioctl() has some faulty logic for choosing which to display. The BSS
params are what were advertised to us, and we would have chosen the
lower of theirs/ours when advertising the HT bits back at them.
So, we /should/ track and fix that so we display the correct A-MPDU
density and size.
However, since I'm a forgetful type, and I don't want to have to re-learn
that this is wrong, drop in a comment so I or someone else fixes it.
Or, when I discover this again in 4 years, I don't have to go digging
too much to remember.

Make the second argument of dtrace_invop() a trapframe pointer.
Currently this argument is a pointer into the stack which is used by FBT
to fetch the first five probe arguments. On all non-x86 architectures it's
simply the trapframe address, so this change has no functional impact. On
amd64 it's a pointer into the trapframe such that stack[1 .. 5] gives the
first five argument registers, which are deliberately grouped together in
the amd64 trapframe definition.
A trapframe argument simplifies the invop handlers on !x86 and makes the
x86 FBT invop handler easier to understand. Moreover, it allows for invop
handlers that may want to modify the register set of the interrupted thread.
Note that mklocale(1) and colldef(1) are no longer used
mklocale and colldef has been replaced by localedef, but they have to be kept
until 10.2 is EOL for mklocale (it has been added to 10.3 as a bootstrap tools)
and until 10.3 is EOL for colldef (it has never been added to bootstrap tools)
Until it has been properly fixed upstream, apply a temporary workaround
for LLVM PR 26999 (in some cases, -save-temps can cause an assertion
failure in clang's -cc1as stage).
