Save 20 bytes per FILE structure, avoid indirect call for
read/write/seek/close operations for normal streams.
Additionally, custom streams has fileno = -2 now, like in glibc.

Unlike vsnprintf, vswprintf does not properly initialize locking
elements of FILE structure, which in some unfortunate cases can result
in lockups in _vfwprintf_internal.
Interesting, the initialization code was removed in
2a915734a32c5aec9a6a76c13bcb074d30e64171 at the same time as it was added
to vsnprintf.

sed -i -e '/Experimentally off - /d' $(grep -rl "Experimentally off - " *)
sed -i -e '/^\/\*[[:space:]]*libc_hidden_proto(/d' $(grep -rl "libc_hidden_proto" *)
should be a nop

Appears to build fine (several .configs tried)

vprintf_internal, so that:
* vprintf() does locking and __STDIO_STREAM_TRANS_TO_WRITE thing,
then calls vprintf_internal
* vsnprintf, vdprintf.c, vasprintf.c use
vprintf_internal directly
This makes sprintf faster (since it doesn't do any locking)
and stops it from pulling in fseek in static compile.

missing headers, other jump relocs removed

Codepaths streamlined. Improved performance for nonthreaded apps
when linked with a thread-enabled libc.
Minor iconv bug and some locale/thread related startup issues fixed.
These showed up in getting a gcj-compiled java helloworld app running.
Removed some old extension functions... _stdio_fdout and _stdio_fsfopen.
