[PATCH v4 0/4] Add new C.UTF-8 locale (Bug 17318)

[Carlos O'Donell]

In order to make implementing the C.UTF-8 locale easier there are
several steps that should be taken before the locale is added:

1) Implement wide ellipsis range handling for UTF-8 to simplify
   the LC_COLLATE description in the locale.
2) Update the UTF-8 charmap processing to include all code points
   (excluding surrogates) and make use of the wide ellipsis ranges.
4) Regenerate the UTF-8 character map with the new characters
   for full code point coverage.

The new C.UTF-8 locale is not added to SUPPORTED because it is
28MiB in size due to the size of the weights array in LC_COLLATE
for the full set of code points. Before we can make C.UTF-8
supported we must simplify the weights processing to use strcmp
and remove the weights array from the binary data. To some extent
this is a reference implementation from which we can test a newer
version or a builtin version that has the size and performance
we expect.

Carlos O'Donell (4):
  Add support for processing wide ellipsis ranges in UTF-8.
  Update UTF-8 charmap processing.
  Regenerate localedata files.
  Add generic C.UTF-8 locale (Bug 17318)
