These are set in the barebox class rather in the corresponding machines
(where they would belong otherwise) to keep the impact of barebox to
oe-core minimal for now.
"multi_v7_defconfig" is used for qemuarm since this is the default
barebox armv7 config that just enables all supported platforms.
"multi_v8_defconfig" is used for qemuarm64 sine this is the default
barebox armv8 config that just enables all supported platforms.
"efi_defconfig" is used for qemux86-64 which is the primary platform
where barebox will not be the first stage bootloader but an EFI payload.
Since these changes make barebox a provider for virtual/bootloader,
explicitly default to u-boot in the corresponding MACHINE configs to not
unnecessarily surprise users.

This adds the support for the barebox bootloader to oe-core. The recipe
is inspired by meta-ptx [1] but is a major rework of the one found there.
Barebox comes with a wide range of supported architectures and follows
the concepts of Linux in various aspects like the driver model, the
shell, or the virtual file system.
This not only eases porting Linux drivers but also makes barebox a
developer-friendly and feature-rich bootloader alternative [2].
For barebox (like for the kernel or other bootloaders) it is quite
likely that people will not just build the original recipe but need to
adapt it, point to custom repositories, apply patch stacks,
COMPATIBLE_MACHINE etc. They may also choose to have different recipe
names for different variants.
Having only a single .bb file and requiring to copy or .bbappend it is
inconvenient and results in unnecessary code duplication. Therefore, the
base support for building barebox is encapsulated in barebox.bbclass
(like kernel.bbclass for the kernel).
Adds barebox to maintainers.inc but excludes it from the maintainers
check since with the current check mechanism barebox would be skipped
(and making the check fail) due to not being the PREFERRED_PROVIDER for
virtual/bootloader.
