guestrpc module to handle VMware backdoor port GuestRPC functionality
Convert existing FreeBSD vmware_hvcall function to take a channel
and parameter arguments.
Added vmware_guestrpc_cmd() to send GuestRPC commands to the VMware
hypervisor. The sbuf argument is used for both the command to send
and to store the data to return to the caller.
The following KPIs can be used to get and set FreeBSD-specific guest
information in key/value pairs:
* vmware_guestrpc_set_guestinfo
- set a value into the guestinfo.fbsd.<keyword> key
* vmware_guestrpc_get_guestinfo
- get the value stored in the guestinfo.fbsd.<keyword> key

release: Stage non-UFS images in vm-images-stage
When the VM image building code was updated to support building
non-UFS images, the vm-images-stage target was not updated to
install those newly built images to the FTP site. As a result, we
have been sending weekly snapshot announcements since August claiming
that ZFS VM images are available when they are not in fact present
anywhere publicly accessible.

bhyve: Move lock of uart frontend to uart backend
Currently, lock of uart in bhyve is placed in frontend. There are some
problems about it:
1. If every frontend should has a lock, why not move it inside backend
as they all have same uart_softc.
2. If backend needs to modify the information of uart after initialize,
it will be impossible as backend cannot use lock. For example, if we
want implement a telnet support for uart in backend, It should wait
for connection when initialize. After some remote process connect it,
it needs to modify rfd and wfd in backend.
So I decide to move it to backend.

vmrun.sh: Add arm64 support
For now, we enumerate disk devices before network devices. This is to
work around a problem wherein u-boot remaps BARs during boot in a way
that bhyve does not handle. Some discussion and experiments suggest
that this can be handled by having bhyve not map BARs during boot on
arm64; until a solution is implemented, however, this workaround is
sufficient for simple usage and doesn't have any real downsides.
The console and bootrom are specified slightly differently versus amd64,
and a few of vmrun.sh's command-line options are amd64-only.

fattime: make the test code build again
This change...
1. replaces calls to timet2fattime/fattime2timet with calls to
timespec2fattime/fattime2timespec. The functions got renamed shortly
after they landed in the kernel but the test code wasn't updated (see
7ea93e912bf0ef).
2. adds a utc_offset stub.
With this, the test code builds and runs as a 32-bit binary (cc -Wall -O2
-m32 subr_fattime.c).

fattime: make the test code check beyond 32-bit time_t limits
On systems that have a 64-bit time_t, the test code now exercises the whole
range of fattime. To do this, this commit...
1. replaces the call to random() with two calls to arc4random() to
generate a 33-bit number of seconds in order to cover the entire range of
fattime [1970,2107]. (32-bits stops just short - in January 2106.)
On systems with 32-bit time_t, the extra bits are discarded and only the
time_t expressible range is tested.
2. casts time_t values passed to printf as longs and changes the format
string to match.
Now, the test code builds, runs, and exercises what it can (i.e., the whole
fattime range or the 32-bit time_t subset of it) on both 32-bit and 64-bit
time_t systems.

fattime: fix fattime to timespec conversion of dates beyond 2106-02-06
It turns out that the only conversion issue was in fattime2timespec, where
multiplying the number of seconds in a day by the number of days overflowed
32-bit unsigned int for dates beyond 2106-02-07 06:28:15.
Casting one of the multiplicands as time_t forces a 64-bit multiplication on
systems where time_t is 64-bits and produces no binary changes on the one
remaining system with 32-bit time_t (namely i386).
Since the code is now tested & fixed, this change removes the fixme comments.

nfscl: Clear out a lot of cruft related to B_DIRECT
There is only one place in the unpatched sources where B_DIRECT is
set in the NFS client and this code is never executed. As such, this patch
removes this code that is never executed, since B_DIRECT should never
be set.
During a IETF testing event this week, I saw a crash in ncl_doio_directwrite(),
but this function is only called if B_DIRECT is set.
I cannot explain how ncl_doio_directwrite() got called, but once this patch
was applied to the sources, the crash did not recur. This is not surprising,
since this patch deleted the function.

nfscl: Do not use nfso_own for delayed nfsrpc_doclose()
When an initial attempt to close an NFSv4 lock returns NFSERR_DELAY,
the open structure is put on a list for delayed closing. When this
is done, the nfso_own field is set to NULL, so it cannot be used by
nfsrpc_doclose().
Without this patch, the NFSv4 client can crash when a NFSv4 server
replies NFSERR_DELAY to a Close operation. Fortunately, most extant
NFSv4 servers do not do this. This patch avoids the crash for any
that do return NFSERR_DELAY for Close.

clang-format: Minor tweaks
Invert KeepEmptyLinesAtTheStartOfBlocks. We used to require an empty
line at the beginning of functions with no local variables, which I
believe is the reason for this setting. Now it is discouraged in new
code.
Tell clang-format to align consecutive macros, since we tend to do that.
clang-format's output isn't quite what we want here. Typically we have
a tab after a #define for some reason, and clang-format doesn't appear
to have an option for that. clang-format will also use a mix of tabs
and spaces to minimize indentation, which is also against our
convention. However, the result looks better with this setting than
without.
