4a7ef88393 Add /boot/dts to the list of default modules. The minimal arm and mips
loader.conf for uboot have this in the list, but the default one
didn't. Since there's no harm and it's a failsafe, add it to the list.

7e3e36068b Move loop to clear TDB_SUSPEND into PT_DETACH case.
The PT_DETACH case above the sendsig: label already looped over all
threads clearing flags in td_dbgflags.  Reuse this loop to clear
TDB_SUSPEND and move the logic out of the sendsig: block.

2a2b23cae2 Pull the PT_ATTACH case out of the 'sendsig:' block.
Most of the conditionals in the 'sendsig:' block are now only different
for PT_ATTACH vs other continue requests.  Pull the PT_ATTACH-specific
logic up into the PT_ATTACH case and simplify the 'sendsig:' block.  This
also permits moving the unlock of proctree_lock above the sendsig: label
since PT_KILL doesn't hold the lock and and the other cases all fall
through to the label.

d6be6d496c Add loader.conf to the list of files that are MD.
loader.conf is also different between machines. On arm it's a minimal
one that's not quite compatible with the default one. On arm it's
minimal for speed, which is good, but there's also extra things in it
relative to the default on which break loading FDT which is bad. This
doesn't address that issue, but instead ensures the minimal one for
arm is used.

A similar issue for mips exists, but since we can have a beri variant
of /boot/loader and a uboot variant, I'm leaving that mess alone for
the moment.

feeaec18d4 Only clear a pending thread event if one is pending.
This fixes a panic when attaching to an already-stopped process after
r325028.  While here, clean up a few other things in the control flow
of the 'sendsig' section:
- Only check for P_STOPPED_TRACE rather than either of P_STOPPED_SIG
  or P_STOPPED_TRACE for most ptrace requests.  The signal handling
  code in kern_sig.c never sets just P_STOPPED_SIG for a traced
  process, so if P_STOPPED_SIG is stopped, P_STOPPED_TRACE should be
  set anyway.  Remove a related debug printf.  Assuming P_STOPPED_TRACE
  permits simplifications in the 'sendsig:' block.
- Move the block to clear the pending thread state up into a new
  block conditional on P_STOPPED_TRACE and handle delivering pending
  signals to the reporting thread and clearing the reporting thread's
  state in this block.
- Consolidate case to send a signal to the process in a single case
  for PT_ATTACH.  The only case that could have been in the else before
  was a PT_ATTACH where P_STOPPED_SIG was not set, so both instances
  of kern_psignal() collapse down to just PT_ATTACH.

50a717a67b Add notes about overlapping copies.
Add notes to each of these that specifically state that results are
undefined if the strings overlap. In the case of memcpy, we document
the overlapping behavior on FreeBSD (pre-existing). For str*, it is
left unspecified, however, since the default (and x86) implementations
do not handle overlapping strings properly.

2ce13699d7 Use proper include file. While <boot/userboot/userboot.h> works, it
only works because we have -Isys on the command line. We also have
-Isys/boot/userboot on the command line, so bring it in directly with
<userboot.h>. No functional change, but it removes one hard to see
dependency on the boot loader's location in sys/boot.

1ec7755286 boot1: also check for NULL device
r325681 fixed a NULL pointer dereference on RPi3 caused by a lack of
functionality in uboot's EFI implementation.  That rev checked the boot1
load path for NULL but not the load device.  In practice if the former
works the latter will as well, but improve correctness by checking each
separately.

175748c982 Make sure the proper loader.rc gets installed.
There were two things wrong. First, the wrong path was listed in .PATH
statement. Second, BOOTSRC wasn't yet defined for the .PATH, so it
didn't properly add it. Third, even if these were right, . was in the
path before, so it wouldn't have worked. Replace this with a simple
loop so the proper loader.rc gets selected.

6789a8b559 dhclient(8) should not close stdio using daemon(3) function.
dhclient(8) is chrooted so opening /dev/null always will fail.
In capability world this is also annoying because we getting error that
open(2) is not permitted in Capsicum. dhclient(8) is closing stdio by
precaching fd to /dev/null before chroot.
This is done few lines below daemon(3) function so let's not try to do that
in daemon(3) function.

cb003dd918 Use syslog service in dhclient(8).
dhclient(8) is failing during boot to connect to the syslog service, because
syslog daemon is started after dhclient(8). This can be reproduced by stooping
syslog daemon and ktrace the dhclient or use kern.trap_enotcap sysctl and boot
the machine. Using the Casper syslog service fix the problem.

7b4fce76cc Introduce syslog service for Casper.
syslog in libc secretly reconnects to the daemon.
Another issue is that we don't have any information from openlog(3) if we
succeeded to open log or not so we don't know if we are ready
to enter cabability mode.
Because all of that we decided we need a syslog service for Caspser.
