If we cannot establish compatibility by only looking at the compat_data we
also check the flash_devices structure's names for a compatible device.

Change '#include <fbsd-*>' to '/include/ "fbsd-*"' in [rm]t*.dtsi
Basically the pre-import work on OpenWRT's dts/dtsi files boils down to:
for f in `ls [mr]t*.dtsi`; do
printf '\n/include/ "fbsd-$f"\n' >> $f
done

An over-long path argument to gssd_syscall could overrun the stack sockaddr_un
buffer. Fix gssd_syscall to not permit that.
If an over-long path is provided, gssd_syscall now returns EINVAL.
It looks like PRIV_NFS_DAEMON isn't granted anywhere, so my best guess is that
this is likely only triggerable by root.

The devtoname() name is strcpyed into a small stack buffer. Sure, we always
expect the name to be ttyXX (or ptyXX). If that's the case, strlcpy() doesn't
hurt.

'buf.value' was previously treated as a nul-terminated string, but only
allocated with strlen() space. Rectify this.

rctl_string_to_rule could previously index below the zeroth element of
racct_types via the macro. Maybe it shouldn't use the macro on
RACCT_UNDEFINED. But given every other RACCT_ definition is non-negative, it
seems pretty easy to foot-shoot this one without the check.

The local of the same name would alias the global, but we didn't even include
the header that defines tsc_freq. Include it and rename the local.

Ordinarily, rctl_write_outbuf frees 'sb'. However, if we are in low memory
conditions we skip past the rctl_write_outbuf. In that case, free 'sb'.

R_Zalloc is essentially a malloc(M_NOWAIT) wrapper. It is possible that 'rnh'
failed to allocate, but 'rmh' succeeds. In that case, we bail out of
rn_inithead() but previously did not free 'rmh'.

'lst' is allocated with 'n1' members. 'n' indexes 'lst'. So 'n == n1' is an
invalid 'lst' index. This is a follow-up to r296009.

This driver thinks that the NCT_MAX_PIN index is a valid index in a few places
(nct_attach() for-loop, as well as NCT_IS_VALID_PIN()). Allocate room for
NCT_MAX_PIN as an index, that is, NCT_MAX_PIN + 1 elements.

If we reached MAXMEMDOM, we would previously try to insert an additional
element and only detect overflow after causing (probably trivial) memory
overflow. Instead, detect the ndomain > MAXMEMDOM case before we write past
the end.

- Always munmap memory regions after mmap'ing them.
- Make sure getpagesize() returns a value greater than 0 and use a
cached value instead of always calling getpagesize(3).
- Remove intermediate variable for assigning from $TMPDIR if set in the
environment to eliminate warnings about pointer conversions with "/tmp",
and to mute an invalid buffer overflow concern from Coverity
(snprintf and tacking on a NUL terminator was alleviating that concern
before).
- Remove useless self-test of psize before it's initialized.
- Check the return values of getrlimit/setrlimit.
Cosmetic changes:
- Replace a `(void*)0` with NULL.
- Do some minor whitespace clean up.
- Remove an unnecessary cast to mmap.
- Make all munmap calls use ATF_REQUIRE_MSG instead of using the:
> if (munmap(..) == -1)
> atf_tc_fail(..)
idiom. Employ the new idiom consistently when calling munmap.

Previously, many errors (such as the PCI device not being attached
to the ppt(4) driver) resulted in bhyve silently exiting without
starting the virtual machine. Now any errors encountered when
configuring a virtual slot for a PCI passthru device should be noted
on stderr.
