lualoader was previously not processing \ as escapes; this commit fixes
that and does better error checking on the value as well.
Additionally, loader.conf had some odd restrictions on values that make
little sense. Previously, lines like:
kernel=foo
Would simply be discarded with a malformed line complaint you might not
see unless you disable beastie.
lualoader tries to process these as well as it can and manipulates the
environment, while forthloader did minimal processing and constructed a
`set` command to do the heavy lifting instead. The lua approach was
re-envisioned from building a `set` command so that we can appropriately
reset the environment when, for example, boot environments change.
Lift the previous restrictions to allow unquoted values on the right hand
side of an expression. Note that an unquoted value is effectively:
[A-Za-z0-9-][A-Za-z0-9-_.]*
This commit also stops trying to weirdly limit what it can handle in a
quoted value. Previously it only allowed spaces, alphanumeric, and
punctuation, which is kind of weird. Change it here to grab as much as it
can between two sets of quotes, then let processEnvVar() do the needful and
complain if it finds something malformed looking.
My extremely sophisticated test suite is as follows:
<<EOF
X_01_simple_string="simple"
X_02_escaped_string="s\imple"
X_03_unquoted_val=3
X_04_unquoted_strval=simple_test

X_09_unknown="${unknown_val}"
X_10_unknown_embedded="truth${unknown_val}"

Future work may provide a stub loader module in userland so that we can
formally test the loader scripts rather than sketchy setups like the above
in conjunction with the lua-* tools in ^/tools/boot.
This extends upon the RFC 6598 support to libalias/ipfw in r357092.

RFC 7143 (11.2.1.8):
An ITT value of 0xffffffff is reserved and MUST NOT be assigned for a
task by the initiator. The only instance in which it may be seen on
the wire is in a target-initiated NOP-In PDU (Section 11.19) and in
the initiator response to that PDU, if necessary.

Older glibc headers did some very nasty things that have since been
sanitised. We could also fix this by adding a linux/getopt.h wrapper
alongside the existing common/getopt.h that #undef's __need_getopt, but
that seems a little more hacky and complicated.

This reverts commit aa37baf3d7.
The reverted commit was motivated by a problem observed on stable/12,
but it turns out that a better solution was committed in r348309 but not
MFCed. So, revert this change since it is unnecessary and not really
correct: it assumes that the order in which module metadata records is
defined determines their order in the output linker set. While this
seems to hold in my testing, it is not guaranteed.

Target value for val has uint32_t type, not uint, adjust used constant.
Change val type to unsigned so that left and right sides of comparision
operator do not expose different signed types of same range [*].
Switch to unsigned long long and strtoll(3) so that 0x80000000 is

By default, axgbe driver does a receiver reset after predefined number
of retries for the link to come up. However, this receiver reset
doesn't always suffice, due to an hardware issue.
In that case, as a workaround, a complete phy reset is necessary.
This patch introduces a sysctl that can be set to 1 to let the driver
reset the phy completely, rather than just doing receiver reset.
The workaround will be removed once the issue is fixed by means
of firmware update.
This patch also fixes the handling of the direct attach cables
properly.

Summary:
The values returned by this function are reported to the gdb client as
the reason for the break in execution, a signal value such as SIGTRAP,
SIGEMT, or SIGSEGV. As such, exact vector numbers can be misidentified.
Return SIGEMT in the default case instead.

The change to use refcounts for pr_uref was mishandled in
prison_proc_free, so killing a jail's last process could add
an extra reference, leaving it an unkillable zombie.
WITHOUT_LIBTHR has been broken for a little over five years now, since the
xz 5.2.0 update introduced a hard liblzma dependency on libthr, and building
a useful system without threading support is becoming increasingly more
difficult.
Additionally, in the five plus years that it's been broken more reverse
dependencies have cropped up in libzstd, libsqlite3, and libcrypto (among
others) that make it more and more difficult to reconcile the effort needed
to fix these options.
Remove the broken options.
