Fix some infrastructure to be able to cope with host and target
machines with different sized basic types (ints, ptrs, etc).
(Idea from pierre@la.tce.com (Pierre Willard).)
* value.c (value_from_longest): Rename from value_from_long.
Handle pointer types as well as integers, so that targets with
different pointer sizes from the host can be accomodated.
* breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
valarith.c, valops.c, valprint.c, value.h, values.c: Rename
uses of value_from_long to value_from_longest.
* eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
the correct pointer type to value_from_long{est}.
* remote-vx.c: Remove obsolete code for calling functions via
vxworks kludge interface (it referenced value_from_long).
* valops.c (value_string): Find malloc with lookup_misc_func, not
raw search.
* breakpoint.c, remote-vx.c: Reword strings printed by
catch_errors callers.
