procfs: Move /proc/pid/fd[info] handling code to fd.[ch] This patch prepares the ground for further extension of /proc/pid/fd[info] handling code by moving fdinfo handling code into fs/proc/fd.c. I think such move makes both fs/proc/base.c and fs/proc/fd.c easier to read.

proc: unsigned file descriptors Make struct proc_inode::fd unsigned. This allows better code generation on x86_64 (less sign extensions). Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
