Add support for early boot access to NVRAM variables, using a new
bhnd_nvram_data_getvar_direct() API to support zero-allocation direct
reading of NVRAM variables from a bhnd_nvram_io instance backed by the
CFE NVRAM device.

channel to a zygote process, rather than sending a function pointer or
service pointer. This avoids transfering pointers between address spaces,
which while robust in this case (due to the zygote being forked() from the
parent) is not generally a good idea, especially in the presence of
increasingly popular control-flow integrity and pointer protection
mitigation schemes. With this change, ping(8) and other sandboxed tools
using libcasper for DNS resolution now work on architectures with tagged
memory again.

The existing ELF image activator requires the brandinfo to provide such
a string unconditionally, even if the executable format in question
doesn't use this type of branding. Skip matching when it's a null
pointer.

This way we can avoid blocking the whole queue in the low memory
situations. It's better to sacrifice some I/O performance by not doing
the aggregation than to add an indefinite wait for more memory.

This is done so that the thread state changes during the switch
are not confused with the thread state changes reported when the thread
spins on a lock.
Here is an example, three consecutive entries for the same thread (from top to
bottom):
KTRGRAPH group:"thread", id:"zio_write_intr_3 tid 100260", state:"sleep", attributes: prio:84, wmesg:"-", lockname:"(null)"
KTRGRAPH group:"thread", id:"zio_write_intr_3 tid 100260", state:"spinning", attributes: lockname:"sched lock 1"
KTRGRAPH group:"thread", id:"zio_write_intr_3 tid 100260", state:"running", attributes: none
The above trace could leave an impression that the final state of
the thread was "running".
After this change the sleep state will be reported after the "spinning"
and "running" states reported for the sched lock.

Newbus handles multiple equally named device classes without problems,
so there is no reason to use slightly cryptic "<foo>_shdci" for them.
In contrast, the driver module name must be unique, so "<foo>_shdci"
is the right name for it.

*** CID 1372598: Null pointer dereferences (FORWARD_NULL)
/lib/libefivar/efivar-dp-parse.c: 3612 in UefiDevicePathLibConvertTextToDeviceNode()
Dereferencing null pointer "FromText".
When ported from Tiano core, I commented this out with an ifdef. That
was in error because we're supposed to fallback to a filepath when
nothing else patches. Instead, restore the original code, but fix
DevPathFromTextFilePath to cope with the conversion to narrow
strings. Also, fix the off-by-one error in the size of the memory it
allocates.
The off by one error is documented in Tiano core bug

*** CID 1372592: API usage errors (BAD_COMPARE)
/lib/libefivar/efivar-dp-parse.c: 2723 in DevPathFromTextiSCSI()
Truncating the result of "strcmp" to "unsigned short" may cause it
to be misinterpreted as 0. Note that "strcmp" may return an integer
besides -1, 0, or 1.
We do this by making StrCmp return either 0 or 1 for equal or
not-equal. There's a bug in the DevPathFromTextiSCSI cast of the
return value and this workaround will fix it without breaking other
users of StrCmp (all of which test for == 0).
https://bugzilla.tianocore.org/show_bug.cgi?id=440 has been filed
upstream to log this issue.
