Barebox provides an option to embed a custom environment image into
barebox binary. This image will be used, when the environment found in
the environment sector is invalid. Both embedded and external images
can be used together, so having both options at the same time is
justified.
This patch sets barebox Kconfig option CONFIG_DEFAULT_ENVIRONMENT_PATH
to user specified path. This way one can use such BR's variables like
BR2_EXTERNAL, TOPDIR etc. to provide paths to custom environment
folders.

Adds support to build barebox with an auxiliary config.
This is useful for building an SPL (Secondary Program Loader) in
addition to the traditional TPL (Tertiary Program Loader). The
Beaglebone Black for example has two barebox configurations:
- am335x_defconfig builds the full barebox bootloader with device
tree
- am335x_mlo_defconfig builds the smaller MLO bootloader that loads
the full barebox bootloader from the eMMC or SD card.
Tested with the following defconfig:
# architecture
BR2_arm=y
BR2_cortex_a8=y
BR2_ARM_EABIHF=y
# system
BR2_TARGET_GENERIC_HOSTNAME="beaglebone"
BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_DEVTMPFS=y

No functional changes. In preparation for the auxiliary barebox build,
boot/barebox is split into two parts:
1. boot/barebox:
- The source and patch specification which are to be shared between the
barebox and barebox-aux packages.
- The barebox-package function and build logic.
2. boot/barebox/barebox:
- The package configuration, fragments, barebox env, etc.
- The actual barebox package make instantiation.

No functional changes: Extracts an argument to the inner-barebox-package
function to automatically determine the uppercase package name. This is needed
to support a 2nd config build. This results in the following renaming:
'BAREBOX' -> '$(1)'
All barebox packages are meant to be built from the same sources, so related
KConfig variables (origin, version and patch directory) are not extracted.

No functional changes: Introduces a barebox-package function towards

Because the function is meant to be called from within a $(eval), all
instances of '$' has to be escaped. I.e. rename '$' -> '$$'.

If we check that the user provides a config file after we call to the
kconfig-package infra, the error message we get is the one for the
kconfig-package infra, not the custom error message we want to show to
the user.
So, only call kconfig-package after we do the check.

Several packages have some logic to apply custom patches that existed
before the BR2_GLOBAL_PATCH_DIR mechanism: at91bootstrap,
at91bootstrap3, barebox, uboot and linux. Currently, the logic of
those packages to apply custom patches is to match
<package-name>-*.patch, which is not consistent with what we've done
for patches stored in the package directory, and for patches stored in
BR2_GLOBAL_PATCH_DIR: in such cases, we simply apply *.patch.
Therefore, for consistency reasons, this commit changes these packages
to also apply *.patch.

Barebox uses KERNEL_ARCH to derive BAREBOX_ARCH, but doesn't
currently handle the case of the x86-64 architecture. In this
case KERNEL_ARCH is x86_64, but BAREBOX_ARCH should be x86
nonetheless.

[Thomas:
- use $(BAREBOX_DIR) instead of $(@D) when defining
BAREBOX_SOURCE_CONFIG, because $(@D) has no value at this point
since we're outside of a make rule. This was causing Barebox to be
constantly rebuilt, since the defconfig path was not a full path,
it was looking like: '/arch/arm/configs/tegra_v7_defconfig'. The
solution of using $(BAREBOX_DIR) has been used to mimic was is done
in the linux package, which uses $(LINUX_DIR).]
