The purpose of envfs_register_partition is to print an error
message when the partition does not exist. Print an error message
from generic code instead and drop this function.

We can compile barebox for multiple boards at once, but currently
they all share a single default environment. This patch adds a
defaultenv_append() which boards can call to customize the default
environment during runtime. Each board now generate default environment
snippets using bbenv-y and add them during runtime with defaultenv_append()

default_environment_path only exists when CONFIG_ENV_HANDLING is enabled.
Boards would have to #ifdef this if they wanted to use
default_environment_path. Use accessor functions instead which can
be ifdeffed on a single place.

Introduce a struct envfs_inode_end with more data.
Today this will just containt the file mode to be able to add the symlink
support.
But this is compatible with the previous envfs version as they will do not
care about the extra as the previous version is just reading the filename and
then consume the extra data without using them.
Increase the envfs version to 1.0

The Linux Kernel defines only one of __LITTLE_ENDIAN and
__BIG_ENDIAN. Endianess can then be tested with #ifdef __xx_ENDIAN. Userspace
always defined both __LITTLE_ENDIAN and __BIG_ENDIAN and byteorder can then
be tested with #if __BYTE_ORDER == __xx_ENDIAN.
As we tend to use a lot of Kernel code in barebox we switch to use the kernel
way of determing the byte order.
As this always causes a lot of confusion add a check to include/common.h to
make sure only one of __LITTLE_ENDIAN and __BIG_ENDIAN is defined.

When barebox headers get included from HOSTCC tools they should not
include other architecture specific headers as barebox might get
cross-compiled. Instead, the tool itself should include "compiler.h".

Fixed the handling of data similiar as found in cramfs.
This fixes the problem with an unreadable defaultenv on big-endian
targets.
The endian macors are now loaded from /asm/common.h by default.
