Allison Ryan Lortie d0219f2597 GLib: add bounds-checked unsigned int arithmetic 
Add some helpers for builds-checked unsigned integer arithmetic to GLib.
These will be based on compiler intrinsics where they are available,
falling back to standard manual checks otherwise.

The fallback case needs to be implemented as a function (which we do
inline) because we cannot rely on statement expressions.  We also
implement the intrinsics case as an inline in order to avoid people
accidentally writing non-portable code which depends on static
evaluation of the builtin.

For now there is only support for addition and multiplication for guint,
guint64 and gsize.  It may make sense to add support for subtraction or
for the signed equivalents of those types in the future if we find a use
for that.

GLib is a general-purpose utility library, which provides many useful
data types, macros, type conversions, string utilities, file utilities,
a mainloop abstraction, and so on. It works on many UNIX-like platforms,
as well as Windows and OS X. GLib is released under the GNU Library
General Public License (GNU LGPL).
