RB_MULTIPLE without RB_SERIAL set is valid, and means 'Video first, then serial'
to the kernel (so kernel messages go to both, but /etc/rc uses video console
(this should be fixed, btw, but another day)). Check for RB_MULTIPLE as well as
RB_SERIAL where we want to to serial things. This means we'll use the old code
for emulation in these situations, which is likely best since we're outputing to
both and the old code is ligher weight allowing both to keep up w/o weird
scrolling things.
With a very large kernel or module the staging area may be too small to
hold it. When this is the case try to allocate more space before failing
in the efi copyin/copyout/readin functions.

In the EFI implementation in U-Boot no ConOut efi variable is created,
this cause loader to fallback to TERM_EMU implementation which is very
very very slow (and uses the ConOut device in the system table anyway).
The UEFI spec aren't clear as if this variable needs to exists or not.

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).

Since local UEFI console is implemented on top of framebuffer,
we need to avoid redrawing the whole screen ourselves, but let
Simple Text Mode to do the scroll for us.
Add settable variables to control teken default color attributes.
The supported colors are 0-7 or basic color names:
black, red, green, brown, blue, magenta, cyan, white.
The current implementation does add some duplication which will be addressed
later.
UEFI specification 2.7A, EFI_BLOCK_IO_PROTOCOL, page 566.
The ioalign property does define the alignment of data buffer.
If the alignment is required and our buffer is not aligned, or if
the data buffer is not multiple of Blocksize, we need to use bounce buffer
to perform the block IO. This is much like with BIOS version, except
there the INT13 needs buffer to be located in low memory.
Additionally, we need to handle disk writes properly.
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.
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.

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.
