Refinements to the output when the EXTERROR_VERBOSE environment is set
When kernel external errors are available they are included in the
err(3) library function messages. In addition to the extended error
itself, the kernel also tracks the kernel file and line number at
which the error was generated. This additional information is not
included in the err(3) messages unless the EXTERROR_VERBOSE environment
variable is present. Currently, when EXTERROR_VERBOSE is present,
all the internal extended error information associated with the
error is printed most of which is redundant with the formatted error
message printed by err(3). This change will add only the kernel
file and line number to the err(3) message when EXTERROR_VERBOSE
is present and set to "brief".
Sample output with bad protection bits to mmap:
guest_16 % ./Example bigfile
Example: mmap bigfile: Invalid argument (unknown PROT bits 0x8)

lpd: Improve robustness
* Check for integer overflow when receiving file sizes.
* Check for buffer overflow when receiving file names, and fully
validate the names.
* Check for integer overflow when checking for available disk space.
* Check for I/O errors when sending status codes.
* Enforce one job per connection and one control file per job (see
code comments for additional details).
* Simplify readfile(), avoiding constructs vulnerable to integer
overflow.
* Don't delete files we didn't create.

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: Gracefully skip unsupported protocols

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.

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.

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.
