More small header changes:

* Remove leading underscores in header preprocessor names
* Regularize names to include directory parts in the file name
* Untabify files
* Update copyright and remove unmaintained cvs $Id$ line

The justification for removing leading underscores comes from a CERTS Secure Coding recommendation: https://www.securecoding.cert.org/confluence/display/cplusplus/DCL32-CPP.+Do+not+declare+or+define+a+reserved+identifier
