- To better support git, remove SVN dependant `$Revision$` from file headers. This does *not* remove: the use of `__REV__` macro in `boostr.inc` and `kernel.asm` - Header Copyright notices updated to 2024. - Minimal white space cleanup (trailing spaces automatically removed). - Note: `asmxygen.py` has a *large* amount of whitespace cleanup, due to incorrect line endings. git-svn-id: svn://kolibrios.org@10051 a494cfbc-eb01-0410-851d-a64ba20cac60
