Merge revision 1203 changes:

- Fix ninja build on all platforms (issue #922).
- Update make_distrib.py to support ninja builds via a new "ninja-build" flag (issue #922).
- Improvements to automate.py:
-- Allow specification of the depot_tools directory via a "depot-tools" flag (issue #592).
-- Add ninja build support via a "ninja-build" flag (issue #922).
-- Allow relative paths for download directories (issue #942).
-- Add the ability to print commands without executing them via a "dry-run" flag.
-- Specifying the "force-clean" flag will also remove the build output directory.
-- Add support for a minimal distribution mode where only release binaries and resources are packaged.
