[PATCH] proc: modify proc_pident_lookup to be completely table driven

Browse Source 
Currently proc_pident_lookup gets the names and types from a table and then
has a huge switch statement to get the inode and file operations it needs.
That is silly and is becoming increasingly hard to maintain so I just put all
of the information in the table.
