event from devd.

529787ba7d Tweak the 'I' flagged value
'I' was omitting 'zero' values. This is not quite correct, and was put
in as a hack but not documented. Remove it. If we find what the hack
was really needed for, we'll either fix the need for it, or invent a
new flagged value type.

332cdd4a22 Implement 'T' field matching.
Implement 'T' field matching. This is needed to prevent false
positives. However, it's not general enough. It only handles one field
and there's a ton of edge cases even with that it likely wouldn't
handle. To do it more generally and also eliminate a lot of the
hackiness that's in this program now, we'd need to creating
directories for lookups ala awk, pearl, python, etc. It appears to be
sufficient, though, to get my keyboard loaded on boot.

9ae5cff01b If we're passed an argument, then treat it as a single NOMATCH event
to parse rather than searching for all events. Pass with new -p arg to
devmatch. devmatch will use that one event rather than walking the
entire tree.

kldload will stop at the first failure. So we need to loop.  Also,
symbolic links may confused kldload into trying (and failing) to load
multiple modules at once, so guard against that.

1ebd4793ad Correct the PNP information generated by the usb driver to match the
artificial NOMATCH usb does in lieu of creating a device_t for devices
with no drivers. Also, correct bus to be 'uhub' since where USB
devices attach, even though 'usb' is more logical, we need the
physical bus here.

1d832237a0 stand/lua: Style pass
These are the style points that I'd like to try and maintain in our lua
scripts:
- Parentheses around conditionals
- Trailing semicolons, except on block terminators
- s:method(...) instead of string.method(s, ...) where applicable

There's likely more, but that'll get hammered out as we continue.

f1cf781a40 stand/lua: Add optional GELI passphrase prompt
Prompt for GELI passphrase when geom_eli_passphrase_prompt has been set to
"YES" in loader.conf(5).

This entailed breaking out the password prompt into its own function that
can be reused between the password compare bits and this prompt that simply
takes the entered password and passes it along in the environment as
kern.geom.eli.passphrase.

I've also added a TODO to re-evaluate later if we want the "password
masking" -- it is currently not functional, so one still can't observe the
length of the password typed at the prompt.

a0bb1acce9 stand/lua: Try to load alternate kernels as directories first
This is the procedure that config.loadkernel tries to go through, but
reloading kernel config didn't use this function. Amend config.loadkernel to
take an optional other_kernel.

While here, be a little more verbose ("Trying to load kernel") so that it's
easy to follow where we've gone wrong.

0afa86db89 stand/lua: Correct some trivial errors in config
An empty module_path to start with isn't ideal, but if all modules are
contained within a kernel directory (which is what we just tested) then it
isn't strictly an error. Don't assume that module_path has a value already.

When we fail to load the kernel, printing the result (which is guaranteed to
be nil) is not intended; print the name of the kernel.

577bda9ddb stand/lua: Correct interpretation of autoboot_delay
autoboot_delay=NO is documented to wait for input and *not* autoboot, which
is the exact opposite of the current behavior.

Additionally, autoboot_delay=-1 is documented to disallow the user from
interrupting the boot (i.e. autoboot immediately), which was not previously
honored.

This also fixes the case insensitive comparison to be truly case
insensitive. This is kind of nit-picky, but the previous version would only
accept "no" and "NO".

8b1e57e44f stand/lua: Don't reload kernel config if we only have one kernel
Don't move this into config.reload because we may want to force reloads if
/boot changes out from under us later.

As a caution: changing kernels in lualoader at the moment might not be
loading all of your modules (in my testing, at least) from loader.conf(5).
This is a known problem.

c678fd7852 trpt(8): Clean up build hack to detect ancient compiler
Detect ancient GCC specifically, rather than using target architecture as a
crude heuristic.

Side note: compilers should really ignore -Wno- and -Wno-error= flags they
don't recognize.  Seems like modern compilers produce warnings instead of
errors.  Though, with -Werror they turn into errors.  Clang's error can be
disabled with -Wno-error=unknown-warning-option, but GCC doesn't seem to
have a named method to disable the specific warning.

9769dd5bee Define CK_MD_TSO for the relevant arches (i386, amd64 and sparc64).
Defaulting to CK_MD_RMO has the unfortunate side effect of generating
memory barriers that are useless on those arches, and the even more
unfortunate side effect of generating lfence/sfence/mfence on i386, even
if older CPUs don't support it.
This should fix the panic reported when using IPFW on a Pentium 3.
Note that mfence and sfence might still be used in a few case, but that
shouldn't happen in FreeBSD right now, and should be fixed upstream first.

ef5fa92a50 stand/lua: Chop off the decimal for numbers passed to setcursor
Decimals screw up the escape sequence and the cursor will not get set. Right
now this only affects setting the cursor for drawing "Welcome to FreeBSD" --
the resulting number after our (x+(w/2)-9) calculation gets output as
"14.0."

This should be fixed at the interpreter level, rather than here, but this is
not a widespread problem at the moment so we'll fix it up in further work.

afe637bbfd Put the pine64 root filesystem on teh correct partition.
The Pine64 root filesystem was incorrectly created directly on the MBR
partition. This can cause the loader to get confused when loading the
kernel from this filesystem.

The loader will see this as a small partition meaning later checks to
ensure it doesn't read past the end of the disk incorrectly report a
failure. This seems to work mostly by accident with the released images as
they are smaller than the reported size, however after growfs has run the
image may no longer boot.
