dev-tools: Add reformat-all.sh for code style unification

dev-tools: Add reformat-all.sh for code style unification

This script will run all files related to the currently checked out
git branch through uncrustify using a standardized style configuration.

Due to a bug in uncrustify 0.64, it is needed to add a special treatment
to one of the files at the moment.  So this both pre- and post-patched
before/after uncrustify is run.  This is to simply to assure that all
file processing will happen consistently each time.

Also added doc/doxygen/doc_key_generation.h to an ignore list, as
it carries some specific Doxygen formatting we should be careful with.
This file is anyhow not so critical and can be managed manually.

The src/compat/compat-lz4.[ch] files are also not touched, as they
are based on upstream formatting.  This makes it easier to update
to a newer LZ4 version later on and even see what the differences
are.

v2 - Include updated config from CodeStyle wiki page
     Remove line lenght restriction for The Great Reformatting
     Update the script with improvements by krzee

v3 - Update with a fixed config from the CodeStyle wiki page
     Corrected a typo in the commit message (0.63->0.64)
     Minor changes to the reformat script (no pushd/popd,
     some new lines moved around, bash->sh)
