[Xastir] constant warnings in term after update and ipv6 (updated) isn't broke

[Tom Russo]

FWIW, Character code (octal) 260  or hex char B0 is the degree symbol in
the extended ASCII character set, which is currently being output to the map 
using stuff like:
 xastir_snprintf(temp_my_course, sizeof(temp_my_course), "%.0f\xB0",
                atof(temp1_my_course));

That is, we're writing the degree sign in the extended ASCII character set
directly to the string being blatted onto the map, and thereby *assuming*
the C locale.  Before the set_to_C_locale/restore_from_C_locale thing was
put in, we were basically always in C locale after a certain stage, and so this
Just Worked.  Now that we're only in C locale in specific portions of the code,
it's borken.

I can see a few ways of addressing it, but the easiest might be to hack in
set_to_C_locale/restore_from_C_locale around all of those snprintfs and 
CreateManagedWidget calls.

There are 21 places where character code \xB0 appears.  Two of those
are commented out.  Not all are for map rendering -- some are in creation
of configuration widgets.

Another approach would be to scribble the degree sign into the display (and
some X dialogs) without resorting to the ASCII character code, but that might
be tricky.  A couple years ago, someone accidentally changed \xB0 into 
UTF-8 encoded degree symbols and that broke map displays.  One would have
to come up with a way of displaying the degree symbol that did not depend on
the locale setting.
