Now that we are using absolute paths we can remove some of the sys.path
mangling that appears in the tools.

We only need to add the path to 'tools/' so that everything can find
modules relative to that directory.

The special paths for finding pylibfdt remain.

At present buildman does not write its own output files (err, done, the
environment) when using -w. However this is useful for when the build is
run with -s to check it.

In fact ProduceResultSummary() reads the result from those files rather
than using the 'result' info directly. So ProcessResult() does not work
with -w at present. It does not print any output.

Fix this by writing output files even when -w is used.

At present the environment used by U-Boot is written to the 'env'
directory. This is fine when the output directory is not the same as the
source directory, but when it is (as with -w) it conflicts with the source
directory of the same name.

Rename 'env' to 'out-env' to fix this.
Signed-off-by: NSimon Glass <sjg@chromium.org>

It is a bad idea to use the default output directory ('..') with -w since
it does a build in that directory and writes various files these.

fdt_region APIs are not part of libfdt. They are U-Boot extension
for the verified boot. Split the declarations related to fdt_region
out of <fdt_region.h>. This allows <linux/libfdt.h> to become a
simple wrapper file, like Linux does.

My goal is to sync lib/libfdt/ with scripts/dtc/libfdt/, that is,
make lib/libfdt/ contain only wrapper files.

fdt_region.c was written only for U-Boot to implement the verified
boot. So, this belongs to the same group as common/fdt_support.c,
which is a collection of U-Boot own fdt helpers.

Move lib/libfdt/fdt_region.c to common/fdt_region.c . This is
necessary only when CONFIG_(SPL_TPL_)_FIT_SIGNATURE is enabled.
