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.

92a5b2ee71 Rename cantwrite() to prepwrite(). The latter is less confusing,
since the macro isn't really a predicate, and it has side-effects.
Also, don't set errno if prepwrite() fails, since this is done in
prepwrite() now.

325d97d0d1 Set errno to EBADF on attempts to write to a stream that is not
writable.  Affected callers include fwrite(), put?(), and *printf().
The issue of whether this is the right errno for funopened streams is
unresolved, but that's an obscure case, and some errno is better than
no errno.

d6ed810a67 Perform conversions straight from the stream buffer instead of scanning
through byte by byte with mbrtowc(). In the usual case (buffer is big
enough to contain the multibyte character, character does not straddle
buffer boundary) this results in only one call to mbrtowc() for each
wide character read.

87275e436a Associate a multibyte conversion state object with each stream. Reset it
to the initial state when a stream is opened or seeked upon. Use the
stream's conversion state object instead of a freshly-zeroed one in
fgetwc(), fputwc() and ungetwc().

This is only a performance improvement for now, but it would also be
required in order to support state-dependent encodings.

8de9e89719 - To make it easier to compile *printf() and *scanf() without
floating-point support, remove default definition of FLOATING_POINT
  from the source, and change the compile-time option to
  NO_FLOATING_POINT.
- Remove the HEXFLOAT option.  It saves an insignificant amount of
  space (<0.1% of the size of libc on i386) and complicates vfprintf()
  and checkfmt().

ccc8c6c31f Use the correct size to allocate, copy and clear argument type tables
after their change from an array of char to an array of enum.
This fixes problems that occurred when using positional arguments in
format strings, particularly with more than STATIC_ARG_TBL_SIZE (8)
of them.

567d74a5ec Re-add macro versions of getc(), getchar(), putc(), putchar(), feof(),
ferror(), fileno() and clearerr(), using the value of __isthreaded to
decide between the fast inline single-threaded code and the more
general function equivalent. This gives most of the performance
benefits of the old unsafe macros while preserving thread safety.
