Cleanly split Linux proc.h (fs) from conflicting Solaris proc.h (process)

Browse Source 
Under linux the proc.h header is for the /proc filesystem, and under
Solaris the proc/h header if for processes.  This patch correctly
moves the Linux proc functionality in a linux/proc_compat.h header
and leaves the sys/proc.h for use by Solaris.  Minor updates were
required to all the call sites where it was included of course.
