ca99cfdd14 Add support for multibyte characters. The challenge here was to use
data structures that scale better with large character sets, instead of
arrays indexed by character value:
- Sets of characters to delete/squeeze are stored in a new "cset" structure,
which is implemented as a splay tree of extents. This structure has the
ability to store character classes (ala wctype(3)), but this is not
currently fully utilized.
- Mappings between characters are stored in a new "cmap" structure, which
is also a splay tree.
- The parser no longer builds arrays containing all the characters in a
particular class; instead, next() determines them on-the-fly using
nextwctype(3).

796263418b Special fix just for
tr -[cC]s '[:upper:]' '[:lower:]'
case (or vice versa):
chars taken from s2 can be different this time
due to lack of complex upper/lower processing,
so fill string2 again to not miss some.

e42eb6838e 1) Fix -C - it was broken since introduced, wrong array sorted
2) Fix last (repeated) char after [:class:], it was \0 in original code

761c008c99 Remove charcoll() stabilization added in 1.16, it gains nothing but conflicts
with ranges.

00611f0457 This patch address two problems.
1st one is relatively minor: according our own manpage, upper and lower
classes must be sorted, but currently not.

2nd one is serious:
	tr '[:lower:]' '[:upper:]'
	(and vice versa) currently works only if upper and lower classes
	have exact the same number of elements. When it is not true, like for
	many ISO8859-x locales which have bigger amount of lowercase letters,
	tr may do nasty things.

	See this page
	http://www.opengroup.org/onlinepubs/007908799/xcu/tr.html
	for detailed description of desired tr behaviour in such cases.

6e9c52b638 When translating and -C is specified, behave as if the complemented set was
in the locale collating order as required by SUSv3.

482711cfa6 When translating and the -c option is specified, handle the case where the
second string argument is more than one character in length in the way
required by SUSv3 (and the way GNU textutils and SVR4 do it).
