In mountd.c, the grouplist structures are linked into a single global
linked list headed by "grphead". The only use of this linked list is
to free all list elements when the exportlist elements are also all being
free'd at the time the exports are being reloaded.
This patch replaces this one global linked list head with a list head in
each exportlist structure, where the grouplist elements for that exported
file system are linked.
The only change is that now the grouplist elements are free'd with the
associated exportlist element as they are free'd instead of all grouplist
elements being free'd after the exportlist elements are free'd. This
change should have no effect in practice.
This is being done, since a future patch that will add a "-I" option for
incrementally updating the exports in the kernel needs to know which
grouplist elements are associated with each exported file system and
having them linked into a list headed by the exportlist element does that.

Factor code into two functions.
read_exportfile() a functon which reads the exports file(s) and calls
get_exportlist_one() to process each of them.
delete_export() a function which deletes the exports in the kernel for a file
system.
The contents of these functions is just the same code as was used to do the
operations, moved into separate functions. As such, there is no semantic change.
This is being done in preparation for a future commit that will add an
option to do incremental changes of kernel exports upon receiving SIGHUP.

This patch moves the code that removes and frees all exportlist elements
out into a separate function called free_exports().
It does the same for the insertion of a new exportlist entry into a list.
It also adds a second argument to ex_search() for the list to use.
None of these changes have any semantic effect. They are being done to
prepare the code for future patches that convert the single linked list
for the exportlist to a hash table of lists and a patch that will do
incremental changes of exports in the kernel.
And it fixes the argument for SLIST_HEAD_INITIALIZER() to be a pointer,
which doesn't really matter, since SLIST_HEAD_INITIALIZER() doesn't use
the argument.

The Windows virtio driver ignores the advertized seg_max field and
assumes the host can accept up to 67 segments in indirect descriptors,
triggering an assert in the bhyve process.
This brings back r282922 but with a couple of changes:
- It raises the block interface segment limit to 128 instead of 67.
- Linux's virtio driver assumes that the segment limit is no
larger than the ring size. To avoid breaking Linux guests,
raise the VirtIO ring size to 128, and cap the VirtIO segment
limit at ring size - 2 (effectively 126).

When the CPU Topology was added to bhyve in r332298 the SMBIOS table was
missed, this table passes topology information to the system and was still
using the old concept of each vCPU is a socket with 1 core and 1 thread.
This code did not even try to use the old sysctl information to adjust
this data.
Correct that by building a proper SMBios table, mapping the > 254 cases to
0 per the SMBios 2.6 specification that is claimed by the structure.

bhyve was previously using stdin for both reading and writing to the
console, which made it difficult to redirect console output. Use
stdin for reading and stdout for writing. This makes it easier to use
bhyve as a backend for syzkaller.
As a side effect, the change fixes a minor bug which would cause bhyve
to fail with ENOTCAPABLE if configured to use nmdm for com1 and stdio
for com2.
bhyveload already uses separate descriptors, as does the bvmcons driver.

Jobs using the @<second> syntax currently only get executed if they exist
when cron is started. The simplest reproducer of this is:
echo '@20 root echo "Hello!"' >> /etc/cron.d/myjob
myjob will get loaded at the next second==0, but this echo job will not
run until cron restarts. These jobs are normally handled in
run_reboot_jobs(), which sets e->lastexit of INTERVAL jobs to the startup
time so they run 'n' seconds later.
Fix this by special-casing TargetTime > 0 in the database load. Preexisting
jobs will be handled at startup during run_reboot_jobs as normal, but if
we've reloaded a database during runtime we'll hit this case and set
e->lastexit to the current time when we process it. They will then run every
'n' seconds from that point, and a full restart of cron is no longer
required to make these jobs work.

This is useful for arm (possibly other arches too) where we want to have
a GENERIC kernel that only include files for the different SoC. Since
multiple SoCs/Board needs the same device we would need to do either :
Include the device in a generic file
Include the device in each file that really needs it
Option 1 works but if someone wants to create a specific kernel config
(which isn't uncommon for embedded system), he will need to add a lots
of nodevice to it.
Option 2 also works but produce a lots of warnings.

The nfsuserd(8) daemon does not function correctly when jails are enabled,
since localhost gets mapped to another IP address and, as such, the upcall
RPC fails.
This patch fixes the problem by doing a getsockname(2) of a socket mapped
to localhost to find out what the correct address is for the comparison
test with the upcall's from IP address.
This patch also adds INET6 support and the required #ifdef's for INET and
INET6. It now uses INET6 by default for the upcalls, if the kernel has
INET6 support and the daemon is also built with INET6 support.

bhyve's NVMe emulation was transferring Identify data back to the guest
incorrectly causing memory corruptions. These corruptions resulted in
core dumps and other system level errors in the guest.
In their simplest form, NVMe Physical Region Page (PRP) values in
commands indicate which physical pages to use for data transfer. The
first PRP value is not required to be page aligned but does not cross a
page boundary. The second PRP value must be page aligned, does not cross
a page boundary, and need not be contiguous with PRP1.
The code was copying Identify data past the end of PRP1. This happens to
work if PRP1 and PRP2 are physically contiguous but will corrupt guest
memory in unpredictable ways if they are not.
Fix is to copy the Identify data back to the guest piecewise (i.e. for
each PRP entry). Also fix a similarly wrong problem when copying back
Log page data.

The NVMe specification defines bits 13:4 of BAR0 as Reserved (i.e. 0x0).
Most drivers do not enforce this, but the Windows NVMe driver does and
will refuse to start the device (i.e. error 10) if any of these bits are
set.
The current BAR size calculation tries to minimize the amount of memory
the device reserves by scaling the BAR size by the maximum number of
queues supported by the device. But unless the device supports a large
number of queue pairs (over 1536), it will reserve too little memory.
The fix is to allocate a minimum of 16K bytes for BAR0.

CXXSTD was added as the C++ analogue to CSTD.
CXXSTD defaults to `-std=c++11` with supporting compilers; `-std=gnu++98`,
otherwise for older versions of g++.
This change standardizes the CXXSTD variable, originally added to
googletest.test.inc.mk as part of r345203.
As part of this effort, convert all `CXXFLAGS+= -std=*` calls to use `CXXSTD`.
Notes:
This value is not sanity checked in bsd.sys.mk, however, given the two
most used C++ compilers on FreeBSD (clang++ and g++) support both modes, it is
likely to work with both toolchains. This method will be refined in the future
to support more variants of C++, as not all versions of clang++ and g++ (for
instance) support C++14, C++17, etc.
Any manual appending of `-std=*` to `CXXFLAGS` should be replaced with CXXSTD.
Example:
Before this commit:
```
CXXFLAGS+= -std=c++14
```
After this commit:
```
CXXSTD= c++14
```
