Passing va_list in syscall does not work.  Temporarily moved syslog and lowsyslog into kernel code and access via a system call.  Need to revisit.  Will probably need to move all of syslog back from fs/syslog to libc/syslog

Misc changes to get a clean build after all of the syslog changes.  There are probably other things still broken

make standard syslog and vsyslog POSIX compliant (also modify non-standard syslog functions for compatibility).  This will break a lot of things until ALL usage of syslog is updated to use the modified interfaces
