Allow the [.<sym>.] expression
This requires a string comparision rather than a character
comparison. Introduce and use __wscollate_range_cmp.

lc_collelem.h: autogenerated table of collating element, taken
from glibc
is_unicode_coll_elem: Check if a UTF-32 string is a collating element
next_unicode_char: return length of prefix from a string constituting
a complete character in the current locale, taking
collating elements into acocunt.

After FreeBSD eventually picked up the bugreport from within
only 5 years, rename __collate_range_cmp to __wcollate_range_cmp
as suggested all along, and make it type safe (wint_t instead of
wchar_t for hopefully obvious reasons...)
While at it, drop __collate_load_error and fix the checks for
it in glob and fnmatch.

is_unicode_equiv compares two UTF-32 values and returns 1 if
both are member of the same Unicode equivalence class, 0 otherwise.
Note that this function only works with precomposed characters
per Unicode normalization form C. It doesn't handle decomposed
characters, just like its counterpart in glibc. I.e., equivalence
class comparison using decomposed chars won't work. Example:
fnmatch("[=n=]", "ñ") == 0
fnmatch("[=ñ=]", "n") == 0
but
fnmatch("[=n=]", "n\x0303") == 1
fnmatch("[=n\x0303=]", "n") == 1
fnmatch("[=n\x0303=]", "n\x0303") == 1
