Since commit 25400090 ("moveconfig: Print a message for
missing compiler"), this tool parses an error message every time an
error occurs during the process in order to detect missing compiler.

Instead of that, we can look for compilers in the PATH environment
only once before starting the defconfig walk.  If a desired compiler
is missing, "make include/config/auto.conf" will apparently fail for
that architecture.  So, the tool can just skip those board, showing
"Compiler is missing.  Do nothing.".

We must ensure this tool is run from the top of source directory
before calling update_cross_compile().  Otherwise, the following

Commit 96464bad ("moveconfig: Always run savedefconfig on the
moved config") changed how defconfig files were updated.

Since then, the function update_defconfig() does not modify defconfig
files at all (instead, they are updated by "make savedefconfig"), so
update_dotconfig() is a better fit for this function.  Also, update
the comment block to match the actual behavior.

Since commit 96464bad ("moveconfig: Always run savedefconfig on
the moved config"), --dry-run option is broken.

The --dry-run option prevents the .config from being modified,
but defconfig files might be updated by "make savedefconfig"
regardless of the --dry-run option.

Move the "if not self.options.dry_run" conditional to the correct
place.

A common case for failed builds is a missing compiler. Print a message
for that case to tell the user concisely which compiler was expected
that was not found.

This patch also has the effect of not printing build errors any longer.
The next patch will add a switch to optionally bring that back.

When moving configs, it is important to know what was defined in the
config header even if it duplicates the configs coming from Kconfig.

This is specifically needed for the case where a config is set to
default 'y' in the Kconfig. This would previously cause the actual value
from the include config to be filtered out, and moveconfig.py would
think that it was 'n'... This means that the value that should be 'y'
is now (in every defconfig) set to 'not set'.

tools/moveconfig.py now defines KCONFIG_IGNORE_DUPLICATES to prevent the
filtering from happening and selecting wrong values for the defconfig.

This will ensure that the order of the defconfig entries will always
match that of the Kconfig files. After one slightly painful (but
still early in the process) pass over all boards, this should keep
the defconfigs clean from here on.

Users must edit the Kconfig first to add the menu entries and then run
moveconfig.py to update the defconfig files and the include configs.

As such, moveconfig.py cannot compare against the '.config' contents.

This tool was originally written for my local use to ease the task
of tons of CONFIG moves, but there have been some requests for
mainlining it.
So, I have tidied up the code with nicer comments, and here it is.

See the comment block of the script for usage.

The first draft was
http://patchwork.ozlabs.org/patch/430422/

Main updates are:
  - Adapted to the single .config configuration
  - Support colored log
  - Support moving multiple options at once
    (and take configs via input file only)
  - Continue even if some boards fail
    (Idea provided by Joe Hershberger)
  - Add more options
  - More comments and code cleanups
