ea9a9a377b Add UTF-8-specific implementations of mbsnrtowcs() and wcsnrtombs(). 
These convert plain ASCII characters in-line, making them only slightly
slower than the single-byte ("NONE" encoding) version when processing
ASCII strings.

6740cd8374 Return the correct value when dst == NULL and conversion has stopped after 
nwc dropping to zero.

1949a3470f Implement the GNU extensions of mbsnrtowcs() and wcsnrtombs(). These are 
convenient when the source string isn't null-terminated.

Implement the other conversion functions (mbstowcs(), mbsrtowcs(), wcstombs(),
wcsrtombs()) in terms of these new functions.

ee446de0b1 Add a function to iterate over all characters in a particular character 
class. This is necessary in order to implement tr(1) efficiently in
multibyte locales, since the brute force method of finding all characters
in a class is infeasible with a 32-bit (or wider) wchar_t.

ddc1eded85 Prefix the names of members of _RuneLocale and its sub-structures 
with ``__'' to avoid polluting the namespace. This doesn't change the
documented rune interface at all, but breaks applications that accessed
_RuneLocale directly.

c05bd9ae25 Buffer partial wide characters more efficiently: instead of storing the 
multibyte representation in conversion state objects, store the
accumulated wide character, set number and number of bytes remaining
to avoid having to derive them every time mbrtowc() is called.

675e7ddbee Grab all the information we need about a character with one call to 
__maskrune() instead of one direct call and one through iswprint().

5e44d7ebe1 Use conversion state objects to store the accumulated wide character, 
low bound, and the number of bytes remaining instead of storing the
raw byte sequence and deriving them every time mbrtowc() is called.
This is much faster -- about twice as fast in some crude benchmarks.

ea4ac135ff Allow encoding modules to override the default implementations of 
mbsrtowcs() and wcsrtombs(). Provide a fast implementation for the
trivial "NONE" encoding.

f789f94dbb Fix braino in previous: check that the second byte in the character 
buffer is non-null when the character is two bytes long, not when
the buffer is two bytes long.

88af941a73 In the absence of proper validation, at least check that null bytes 
do not appear as anything but the first byte of a multibyte character.

45a11576f3 Use a binary search to find the range containing a character in 
RuneRange arrays. This is much faster when there are hundreds of
ranges (as is the case in UTF-8 locales) and was inspired by a
similar change made by Apple in Darwin.
