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.

18b2031298 Scan the source string for invalid wide characters in wcsrtombs()
in the dst == NULL case.

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.
