The D_PARTNONE is documented to make it possible to open raw MBR
partition, but the current disk_open() does not really implement this
statement.
The current code is checking partition against -1 (D_PARTNONE) but does
attempt to open partition table in case we do have FreeBSD MBR partition type.
Instead, we should check -2 (D_PARTWILD).
In case we do have MBR + BSD label, this code is only working because
by default, the first BSD partiton is created starting with relative sector
0, and we can still access the BSD table from that MBR slice.

This is like efi_devpath_match, but allows differing device media
paths. Those just specify the partition information.

* Fix boot env back compat
zfsboot must try zfsloader before loader in order to remain compatible
with boot environments created prior to zfs functionality being rolled
into loader proper.
* Improve comments in zfsboot
Explain the significance of the load path order, and put the comment
about looping through the paths in the appropriate scope.

loader.rc has comment lines without a trailing space, which get
interpreted as commands. Avoid this by only matching against the

This adds some new commands to loader :
- pnpmatch
This takes a pnpinfo string as argument and tries to find a kernel module
associated with it. -v and -d option are available and are the same as in
devmatch (v is verbose, d dumps the hints).
- pnpload
This takes a pnpinfo string as argument and tries to load a kernel module
associated with it.
- pnpautoload
This will attempt to load every kernel module for each buses. Each buses are
probed, the probe function will generate pnpinfo string and load kernel module
associated with it if it exists.
Only simplebus for FDT system is implemented for now.
Since we need the dtb and overlays to be applied before searching the tree
fdt_devmatch_next will load and apply the dtb + overlays.
All the pnp parsing code comes from devmatch and is the same at 99%.

we leak 'name'.
mod_load() does leak 'filename'.
mod_loadkld() does not need to check fp, file_discard() does check.
Since the partition/slice names do vary in length, check the length
of the fixed part of the line against 3 * 8, if the lenth is less than
3 tab stops, print out extra tab.
use snprintf() instead of sprintf.
This is a prerequisite of unifying kernel zlib instances.

looping over the filesystem modules rather than doing a malloc + free
each time through the loop. In addition, nothing changes from loop to
loop, so setup the new devinfo outside the loop as well.
The bug and patch is reported against 11.2, but it is good idea to have
the check in place for all versions.

We're storing an EFI_HANDLE, not an pointer to a handle. Since
EFI_HANDLE is a void * anyway, this has little practical effect since
the conversion to / from void * and void ** is silent.
Small mis-merge from multiple WIP resulted in block io media handles getting
double-initialized. This resulted in some installations oddly landing at the
mountroot prompt.

If we do have GPT on disk, read the disk size from it and do not
call int13.
Since int13 does report bogus informatiopn too often, rather trust the
partition table. We are using the same strategy with loader.
