PATCH 1/1 2.4: export scheduling information from /proc

Menacing Marcelo,

Attached patch exports scheduling policy and real-time priority from /proc/<pid>/stats.

This code is in 2.4-ac and 2.5.

This does _not_ break previous versions of procps -- there is no harm and it is fully backward compatible. New versions, starting with 2.0.8, can parse this information.

Patch is against 2.4.20-pre9. Please, apply.
