Jacques Vidrine 8b7358ca43 Introduce a uiomove_frombuf helper routine that handles computing and 
validating the offset within a given memory buffer before handing the
real work off to uiomove(9).

Use uiomove_frombuf in procfs to correct several issues with
integer arithmetic that could result in underflows/overflows.  As a
side-effect, the code is significantly simplified.

Add additional sanity checks when computing a memory allocation size
in pfs_read.

Submitted by:	rwatson  (original uiomove_frombuf -- bugs are mine :-)
Reported by:	Joost Pol <joost@pine.nl>  (integer underflows/overflows)
