From Lorenz Meier: The implementation of access() as vararg macro has the issue that any function call with the same name (even in a C++ class) will match with it and result in a compile error. I have replaced it with a small function, and tried to have decent documentation as well. This resolves the compile issue, and shouldn’t have negative side effects for users of the function.

Fix prolblems with redefinitions of fdb macro.  With the fix to the syslog prototype, a LOG priority must now be the first paramter.  Fixed by replacing all occurrences of fdbg with syslog(LOG_DEBUG, and eliminating the macro redefinitions.  Noted by Sebastien Lorquet.
