Regex support for extra-large character sets not compiled in
if wchar_t is not wide enough for it.
The utf-8 properly throws exceptions when encountering characters
that it cannot represent, instead of silently ignoring the
situation and continuing with incorrectly computed data.
* regex.c (FULL_UNICODE): New macro.
(CHAR_SET_L3, CHAR_SET_L2_LO, CHAR_SET_L2_HI): Only defined
if full unicde is available.
(CHSET_XLARGE, cset_L3_t, struct xlarge_char_set,
L2_full, L3_fill_range, L3_contains): Ditto.
(unon char_set): Member x1 present only under FULL_UNICODE.
(char_set_destroy, char_set_add, char_set_add_range,
char_set_contains): CHSET_XLARGE cases only available on
FULL_UNICODE.
(char_set_compile): Default cst variable to CHSET_LARGE.
* utf8.c (FULL_UNICODE): New macro.
(conversion_error): New function.
(utf8_from_uc): Throw error if not FULL_UNICODE and character is
outside the BMP.
(utf8_decode): Likewise.

can be converted to a type long and vice versa. The configure
script tries to detect the appropriate type to use. Also,
some run-time checking is performed in the streams module
to detect which conversions specifier strings to use for
printing numbers.

abstraction instead of directly using C standard I/O,
to eliminate most uses of C formatted I/O,
and fix numerous bugs, such variadic argument lists which
lack a terminating ``nao'' sentinel.
Bug 28033 is addressed by this patch, since streams no longer provide
printf-compatible formatting. The native formatter is extended with
some additional capabilities to take over.
The work on literal objects is expanded and they are now used
throughout the code base.
Fixed bad realloc in string output stream: reallocating by number
of wide chars rather than bytes.

Bumped version numbers, and cleaned up trailing whitespace from some files.

Fix unsigned and plan char * mixing.

Added utf8_encode, utf8_decoder_init, utf8_decode.

This is incomplete. There are too many dependencies on
wide character support from the C stream I/O library,
and implicit use of some encoding which may not be UTF-8.
The regex code does not handle wide characters properly.
Character type is still int in some places, rather than wchar_t.
Test suite passes though.
