[RISCV] Add MERGE, MVM, and MVMN to isSignExtendedW in RISCVOptWInstrs. (#183433)
These instructions are a combination of AND/OR/XOR which return sign
extended values if all inputs are sign extended.
[RISCV] Partial support for using PPAIRE.B/H to optimize unaligned load sequences. (#183423)
Patterns are based on patterns we use for Zbkb. We can't copy all
patterns because PPAIRE.B/H are a little different than PACKW/PACKH.
PACKW packs the first 16 bits of rs1 and rs2 and sign extends the upper
32 bits of rd. PACKH packs the first 8 bits of rs1 and rs2 and puts
zeros in bits 16 of rd.
PPAIRE.B copies the even bytes of rs1 to the even bytes of rd and copies
the even bytes of rs2 to the odd bytes of rd. PPAIRE.H is similar, but
copys halfwords instead of bytes. We can treat them equivalently to
PACKH/PACKW when we know that we only care about the lower halfword or
word, respectively of the result.
security/py-unicode-show: New port: Detect and annotate suspicious Unicode characters in text or files
unicode-show is a utility that reads text input (from standard input
or files) and highlights suspicious Unicode characters, such as
those outside the safe ASCII range. This tool is useful for identifying
potentially malicious or misleading Unicode characters in source
code, logs, or user input.

[RISCV] Treat zext.h as a separate instruction from pack(w) with Zbkb. (#183364)
The Zbb encoding for zext.h is a subset of the encoding for pack(w).
There is a statement in the ISA manual that says "For RV32, the pack
instruction with rs2=x0 is the zext.h instruction. Hence, for RV32, any
extension that contains the pack instruction also contains the zext.h
instruction"
This patch makes the zext.h instruction mnemonic canonical when only
Zbkb is enabled. -Mno-aliases will not disable the printing of zext.h. I
believe this matches binutils.
I've taught the assembler to remap PACK/PACKW to ZEXT_H to make printing
parsed assembly match the disassembler output.

lpr: Add deprecation notice
These programs require elevated privileges to work and have not seen
regular maintenance in decades. Unless someone steps up and overhauls
them, we will have to remove them before 16.0. Better-maintained
alternatives are available in ports (print/cups, sysutils/LPRng).

libfetch: Fail hard if interrupted while connecting
This fixes an issue where the first address that DNS returns is blocked
by a packet filter, so we hang for a while, then the user hits Ctrl-C,
interrupting connect(2), whereupon we move on to the next address, get
a connection, request the file, and return to fetch(1), which sees that
SIGINT was caught and bails.
Note that we make no attempt to enforce fetchTimeout in the connection
phase, and never have. It's feasible, but non-trivial, so we'll leave
it as an exercise for future us.

Migrate to the new encryption key API rather than poking at the
key struct directly.
Notably this driver was very clear about its expectation the net80211
key layout w/ key, TX MIC and RX MIC matches the firmware layout
and just memcpy()'ed it. That has been refactored.

Fix failing passdb tests

smb.conf we generate for testing to reflect this.
bsdinstall: fix EFI boot entry creation
update_uefi_bootentry assumes that the caller sets FREEBSD_BOOTNAME and
mntpt, which isn't the case anymore. The result is that there is no
"FreeBSD" boot entry created/updated after install. Most machines manage
to boot from the removable media path (if the loader is installed there
too), but some don't.
Take the loader's path as an argument and rename the variable used in
the ZFS mirror loop so mntpt can be reused below.
Also mark nentries as a local variable so it doesn't leak out of the
function.

nullfs: Fix handling of doomed vnodes in nullfs_unlink_lowervp()
nullfs_unlink_lowervp() is called with the lower vnode locked, so the
nullfs vnode is locked too. The following can occur:
1. the vunref() call decrements the usecount 2->1,
2. a different thread calls vrele() on the vnode, decrements the
usecount 0->1, then blocks on the vnode lock,
3. the first thread tests vp->v_usecount == 0 and observes that it is
true,
4. the first thread incorrectly unlocks the lower vnode.
Fix this by testing VN_IS_DOOMED directly. Since
nullfs_unlink_lowervp() holds the vnode lock, the value of the
VIRF_DOOMED flag is stable.
Thanks to leres@ for patiently helping to track this down.
