layout: Add -i <region>[:<file>] support

Browse Source 
Add an optional sub-parameter to the -i parameter to allow building the
image to be written from multiple files. This will also allow regions to
be read from flash and written to separate image files.

This is a rebase of a patch that was ported from chromiumos. A lot of
things have changed, but the idea is the same.

Original patch by Louis Yung-Chieh Lo <yjlou@chromium.org>:
Summary: Support -i partition:file feature for both read and write.

Ported version by Stefan Tauner <stefan.tauner@student.tuwien.ac.at>
and Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006@gmx.net>:
Summary: [PATCH 2/6] layout: Add -i <region>[:<file>] support.
