The cd handles should be collected as list of partitions. Some systems also
provide base name for block device (like PciRoot(0x0)/Pci(0x5,0x0)), we need
to be careful about those.
To make out life a bit easier, we prepare not just an array of handles, but we
allocate pdinfo struct for each handle and devicepath, then we can simplify
our work to sort the devices.

If veriexec is enabled we should verify it first.
Note that on EFI systems the verification was already done

The HandleProtocol() is deprecated interface and we should use OpenProtocol()
instead. Moreover, in some firmware implementation(s), the HandleProtocol()
does return device path using static storage, so we can not keep the value
returned there. With same firmware, the OpenProtocol() does return data we
do not need to clone.

Summary:
efi loader does not work with static network parameters. It always uses
BOOTP/DHCP and also uses RARP as a fallback. Problems with DHCP servers can
cause the loader to fail to populate network parameters.

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.
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.

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.

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.

When set, we ignore all the hints that the UEFI boot manager has set
for us. We also always fail back to the OK prompt when we can't find
the right thing to boot rather than failing back to the UEFI boot
manager. This has the side effect of also expanding the cases where we
fail back to the OK prompt to include when we're booted under UEFI,
but UEFI::BootCurrent isn't set in the environment and we can't find a
proper place to boot from.

Fetch FreeBSD-LoaderEnv UEFI enviornment variable. If set, read in
loader environment variables from it. Otherwise read in
/efi/freebsd/loader.env. Both are read relative to the device
loader.efi loaded from (they aren't full UEFI device paths)
Next fetch FreeBSD-NextLoaderEnv UEFI environment variable. If
present, read the file it points to in as above and delete the UEFI
environment variable so it only happens once.
This lets one set environment variables in the bootloader.
Unfortunately, we don't have all the mechanisms in place to parse the
file, nor do we have the magic pattern matching in place that
loader.conf has. Variables are of the form foo=bar. No quotes are
supported, so spaces aren't allowed, for example. Also, variables like
foo_load=yes are intercepted when we parse the loader.conf file and
things are done based on that. Since those aren't done here, variables
that cause an action to happen won't work.

Add map-vdisk and unmap-vdisk commands to create virtual disk interface on top of file. This will allow to use disk image from file system to load and start the kernel.
By mapping file, we create vdiskX device, the device will be listed by lsdev [-v] and can be accessed directly as ls vdisk0p1:/path or can be used as value for currdev variable.
vdisk strategy function does not use bcache as we have bcache used with backing file. vdisk can be unmapped when all consumers have closed the open files.
In first iteration we do not support the zfs images because zfs pools do keep the device open (there is no "zpool export" mechanism). Adding zfs support is relatively simple, we just need to run zfs disk probe after mapping is done.

earlier as well, as they don't depend on how the console is
setup. This will allow us to read files earlier in boot, so any rare
error messages that this might move only to the EFI console will be an
acceptable price to pay. Also tweak the order of has_kbd so it resides
next to the rest of the console code. It needs to be after we initialize
the buffer cache.
