1055ebaeb1 lldb: add rule to generate LLDBWrapLua.cpp
Building lldb's lua/python bindings requires swig, but we do not want to
include it in the FreeBSD base system (as a build tool) because it has
non-trivial dependencies.  As a workaround, add a make rule to generate
LLDBWrapLua.cpp, and we will commit the generated file.

Requires the swig30 package.

0f6c6dff74 Note some functions that appeared in First Edition Unix
These functions first appeared in the First Edition of Unix (or earlier in the
pdp-7 version). Just claim 1st Edition for all this. The pdp-7 code is too
fragmented at this point to extend history that far back.

efd93357ab Retire procfs-based process debugging.
Modern debuggers and process tracers use ptrace() rather than procfs
for debugging.  ptrace() has a supserset of functionality available
via procfs and new debugging features are only added to ptrace().
While the two debugging services share some fields in struct proc,
they each use dedicated fields and separate code.  This results in
extra complexity to support a feature that hasn't been enabled in the
default install for several years.

59b95f1bfb Fix pkgfs stat so it satisfies libsecureboot
We need a valid st_dev, st_ino and st_mtime
to correctly track which files have been verified
and to update our notion of time.

ve_utc_set(): ignore utc if it would jump our current time
by more than VE_UTC_MAX_JUMP (20 years).

Allow testing of install command via userboot.
Need to fix its stat implementation too.

bhyveload also needs stat fixed - due to change to userboot.h

Call ve_error_get() from vectx_close() when hash is wrong.

Track the names of files we have hashed into pcr

For the purposes of measured boot, it is important
to be able to reproduce the hash reflected in
loader.ve.pcr
so loader.ve.hashed provides a list of names in the order they
were added.

cd5add7d31 Document when execl and execp entered unix.
For this, things are complicated. The first mention in the manual was in the 4th
edition manual (as an add on to exec(II)).  The 2nd and 3rd editions didn't have
these in the manual (either as a separate page, or as an add-on to exec(II)). We
don't have good 1st, 2nd or 3rd edition distributions to look in. However,
there's a tape labeled 'last1120c' that we do have. This tape contains the last
version of the V2 edition of the C compiler on it (just after C got struct). On
this tape there was a libc.sa archive that contains source for execl and
execp. This source is sufficiently different from the V5 sources (which are the
next ones we have sources for) and have a slightly different calling convention
than later sources, suggesting that the early date for the last1120c tape is
correct (in that era, the epoch changed every year, leading to a one or two year
ambiguity on when the files could have been modified) and it should be though of
as V2. Since this was also a time of compiler development, and the calling
convetions are known to be under evolution, and since the rest of the sources in
libc.sa are consistent, that's further evidence that V2 is likely. Finally, 2nd
edition was the last version to fully support the 11/20 because it lacked many
basic features and bell labs moved off it to the 11/45 as soon as they could
afford to buy one, around this time era. The unix manuals make it sound like V3
might have supported the 11/20, but the same intro could also be read to mean it
didn't, at all, and that V3 was the first rewrite for the 11/45 ahead of the
rewrite in C that came with V4.

Taken together, the evidence leans most heavily to V2 (90% IMHO), and slightly
to V3 (8%) or possibly V4 (2%). I've not put all this in the man page, but have
left it here in case someone notices in the future that V4 is the first manual
page for it.

f62b731846 libssp: don't compile with -fstack-protector*
This similarly matches what we do in libc; compiling libssp with
-fstack-protector* is actively harmful.  For instance, if the canary ctor
ends up with a stack protector then it will trivially trigger a false
positive as the canary's being initialized.

This was noted by the reporter as irc/ircd-hybrid started crashing at start
after our libssp was MFC'd to stable/11, as its build will explicitly link
in libssp. On FreeBSD, this isn't necessary as SSP bits are included in
libc, but it should absolutely not trigger runtime breakage -- it does mean
that the canary will get initialized twice, but as this is happening early
on in application startup it should just be redundant work.
