Not all uses of atoi() or various strto* routines in Wireshark expect
the string to contain *only* a number, so not all uses should require
that the byte after the number be a '\0'. Have the ws_strto* routines
take a "pointer a pointer set to point to the character after the
number" argument, and have the callers do the appropriate checks of the
character after that.
This fixes the VMS trace reading code so that it can read those files
again.
The get_ routines are handed command-line arguments, so they *do* expect
the string to contain only a number; have them check to make sure the
byte after the number is a '\0'.

-1 is not an unsigned number. For that matter, neither is +1;
"unsigned" means "without a sign", and they both have signs.
ANSI C's strto{whatever} routines - even the ones that supposedly are
for "unsigned" values - and the GLib routines modeled after them allow a
leading sign, so we have to check ourselves.

That's a less gross hack to suppress load failures due to not having
libwiretap than providing a no-op failure-message routine, as it at
least allows other code using a failure-message routine, such as
cmdarg_err() and routines that call it, to be used.
We really should put libwiretap and libwireshark plugins into separate
subdirectories of the plugin directories, and avoid even looking at
libwireshark plugins in programs that don't use libwireshark.
