This check was previously in `create` only, not applying to renames. It
should really be applied at the libbe level, so that we can avoid
writing about this restriction over and over again.
While we're here: `bectl rename` always succeeds, even when it doesn't.
Start returning the error.

The props feature to this API was added as a "just in case", with no
planned consumer. It turns out that it was implemented incorrectly,
tapping out props for the BE root (BE's parent) rather than the BE

If the pfctl_add_eth_rule() ioctl fails return the errno, not the error
returned by ioctl(). That will give us slightly more insight into what
went wrong, because ioctl() would always return -1.

To support cc -pg on arm64 we need to implement .mcount. As clang and
gcc think it is function like it just needs to load the arguments
to _mcount and call it.
On gcc the first argument is passed in x0, however this is missing on
clang so we need to load it from the stack. As it's the caller return
address this will be at a known location.

kern_time.c/cputick2timespec() (it is used for clock_gettime() for
querying process or thread consumed cpu time) Uses cputick2usec()
and then needlessly converting usec to nsec, obviously losing
precision even with fixed cputick2usec().
kern_time.c/kern_clock_getres() uses some weird (anyway wrong)

Traditionally the GEOM's primary channel of information from kernel to
user-space was confxml, fetched by libgeom through kern.geom.confxml
sysctl. It is convenient and informative, representing full state of
GEOM in a single XML document. But problems start to arise on systems
with hundreds of disks, where the full confxml size reaches many
megabytes, taking significant time to first write it and then parse.
This patch introduces alternative solution, allowing to fetch much
smaller XML document, subset of the full confxml, limited to 64KB and
representing only one specified geom and optionally its parents. It
uses existing GEOM control interface, extended with new "getxml" verb.
In case of any error, such as the buffer overflow, it just transparently
falls back to traditional full confxml. This patch uses the new API in
user-space GEOM tools where it is possible.

- Refine the checks for ARM mapping symbols and apply them on arm64 as
well as 32-bit arm. In particular, mapping symbols can have
additional characters and are not strictly limited to just "$a" but
can append additional characters (e.g. "$a.1"). Add "$x" to the
list of mapping symbol prefixes.
- Clear the LSB of function symbol addresses. Thumb function
addresses set the LSB to enable Thumb mode. However, the actual
function starts at the aligned address with LSB clear. Not clearing
the LSB can cause pmcannotate to pass misaligned addresses to
objdump when extracting disassembly.

Some PCI devices especially GPUs require a ROM to work properly.
The ROM is executed by boot firmware to initialize the device.
To add a ROM to a device use the new ROM option for passthru device
(e.g. -s passthru,0/2/0,rom=<path>/<to>/<rom>).
It's necessary that the ROM is executed by the boot firmware.
It won't be executed by any OS.
Additionally, the boot firmware should be configured to execute the
ROM file.
For that reason, it's only possible to use a ROM when using
OVMF with enabled bus enumeration.
