[ES40-developers] Code formatting

[Camiel V. <iam...@gm...>]

Hello Everyone,

I've committed a couple of large patches today and yesterday to
improve both multithreading and exception handling. This results in
restoration of the functionality of the <break>  menu on the serial
ports. After these changes, I've run all code through a source code
formatter to make the coding style a bit more consistent. I'd like you
to check out the new code, and let me know if there are aspects of the
source formatting that you don't like. I'm hoping this will improve
readibility of the source code, and will help to develop a set of
guidelines for coding style.

Thanks!

Camiel.

P.S. I've tagged the repository before committing the re-formatted
code; if anything has gone horribly wrong, we can revert...
