b9f745fdb1 loader: fall back to term_emu on efi console with serial backend
In case of efi console having serial backend (video + serial or only serial),
we need to stick with old emulator till we can draw console.

Eventually we would need to get console terminal emulator to be removed
from serial console because the serial link already has the terminal.

However, we need to implement comconsole on all efi platforms first, then
we need the ability to draw console, so we do not have to use SimpleTextOutput
protocol (which will write both on video and serial in case of multiplexed
ComOut).

56758831fe loader: use teken teminal emulator for x86 and uefi
Replace mini cons25 emulator with teken, this does enable us proper console
terminal for loader and will make it possible to implement different
back end callbacks to draw to screen.

At this time we still only "draw" in text mode.

da4961c796 loader: add HTTP support using UEFI
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.

83ffeb8b52 Introduce efi_devpath_same_disk
This is like efi_devpath_match, but allows differing device media
paths. Those just specify the partition information.

16b07b25c4 Add wrapper functions to convert strings to EFI_DEVICE_PATH
In anticipation of new functionality, create routines to convert char *
and a CHAR16 * to a EFI_DEVICE_PATH
	EFI_DEVICE_PATH *efi_name_to_devpath(const char *path);
	EFI_DEVICE_PATH *efi_name_to_devpath16(CHAR16 *path);
	void efi_devpath_free(EFI_DEVICE_PATH *dp);
The first two return an EFI_DEVICE_PATH for the passed in paths. The
third frees up the storage the first two return when the caller is
done with it.

6564182252 loader.efi: efi variable rework and lsefi command added
This update does add diag and debug capabilities to interpret the efi
variables, configuration and protocols (lsefi).

The side effect is that we add/update bunch of related headers.

00a47597a3 Implement efiblk_get_pdinfo_by_device_path
Lookup a block device by it's device path. We use a 'loose' lookup
whereby we scan forward to the first Media Path portion of the device
path, then look at all our handles for one whose first Media Path
matches. This will also work if the device path pointed to has a
following file path (or paths) as that's ignored. It assumes that
there's only one media path node that describes the entire device,
which is true as of the latest UEFI spec (2.7 Errata A) as far as I've
been able to determine.

Returns true if the first node pointed to by devpath1 is identical to
the first node pointed to by devpath2, with care taken to not read
past the end of the valid parts of either devpath1 or
devpath2. Otherwise, returns false.

fa9dc8d3ed Refactor currdev setting
Refactor the currdev setting to find the device we booted from. Limit
searching when we don't already have a reasonable currdev from that to
the same device only. Search a little harder for ZFS volumes as that's
needed for loader.efi to live on an ESP.

5722dd8394 Move the env convenience routines out of boot1.c.
These routines are more generally useful. Even though boot1 is on its
way out, it's better to make these common during the transition than
copy them.

Leave the mechanism to free and reprobe all devices if one day we want
