To avoid failures when the large 18MB nvidia.ko module is being loaded,
increase EFI_STAGING_SIZE from 64MB to 100MB on x64 systems.
Leave the other platforms at 64MB.
The code in efihttp.c was assuming that dv_open wouldn't be called if
dv_init failed. But the dv_init return value is currently ignored.
Add a new variable, `efihttp_init_done` and only proceed in dv_open if
it's true. This fixes the loader on systems without efi http support.
NANDFS has been broken for years. Remove it. The NAND drivers that
remain are for ancient parts that are no longer relevant. They are
polled, have terrible performance and just for ancient arm
hardware. NAND parts have evolved significantly from this early work
and little to none of it would be relevant should someone need to
update to support raw nand. This code has been off by default for
years and has violated the vnode protocol leading to panics since it
was committed.

Add support for an HTTP "network filesystem" using the UEFI's HTTP
stack.
This also supports HTTPS, but TianoCore EDK2 implementations currently
crash while fetching loader files.
Only IPv4 is supported at the moment. IPv6 support is planned for a
follow-up changeset.
Note that we include some headers from the TianoCore EDK II project in
stand/efi/include/Protocol verbatim, including links to the license instead
of including the full text because that's their preferred way of
communicating it, despite not being normal FreeBSD project practice.

There are many new features in ZoF. Most, if not all, do not effect read only usage.
Encryption in particular is enabled at the pool level but used at the dataset level.
The loader obviously will not be able to boot if the boot dataset is encrypted, but
should not care if some other dataset in the root pool is encrypted.

At least since version 4.0.0, QEMU became bug-compatible with PowerVM's
vty, by inserting a \0 after every \r. As this confuses loader's
interpreter and as a \0 coming from the console doesn't seem reasonable,
it's now being filtered at OFW console input.

Add the customary warnings to disable format checking on armv7. Code

This is a primary boot loader that is intended to implement the
gptboot partition selection algorithm just like we did for BIOS
booting. While the preferred method for UEFI is to use the UEFI Boot
Manager protocol, there are situations where that can't be done: some
BIOS makers interfere with the protocol in unhelpful ways, there's a
new standard for a zero variable write from the client OS, and finally
for USB drives that might be mobile between systems with multiple
partitions there needs to be a media stable way to select.

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.

Explain the significance of the load path order, and put the comment
about looping through the paths in the appropriate scope.

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%.
