[Bug runtime/6697] New: need more access_ok() checks in runtime/tapsets

["fche at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

Each user_*() tapset call in conversions.stp should set_fs(USER_DS) and restore it;
Each user/kernel_*() tapset or runtime type call should check the pointers with
access_ok(), redundantly if necessary.

See also bug #1288, which could be started upon with an access_ok()-based
address filtering function.
