GCC plugin integration

[sergeuz]

Problem

1. The GCC plugin needs to be integrated with our build system in order to update firmware message files during the build.

2. The firmware should be able to expand its own logging based on message IDs.

Solution

1. Update makefiles to invoke the plugin for every source file that is being compiled.

2. Provide a tool to convert a message file to a source file containing log messages data. Update formatter classes to perform a lookup in the log messages data for every message based on its ID.

Steps to Test

1. Build the system firmware.

2. Invoke the update-msg tool to generate a source file with the log messages data in the application directory.

$ update-msg <source message file> <destination source file>

3. Build the application.
