Step 17: libc_hidden_proto removal (almost all).

NPTL sh4 port build and work fine. All committed to allow Khem Ray working on a working branch to integrate the ARM nptl port. MIPS nptl port not tested but should still building and working fine. There are some other part non yet merged with trunk (misc/internals and some headers file that need some more work). Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>

operations internal to libc. The futexes should not be visible to anything other than libc. These changes clean up futex and STDIO.

NPTL is not currently supported.

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.

were including libc-lock.h which had a bunch of weak pragmas. Also,
uClibc supplied a number of no-op weak thread functions even though
many weren't needed. This combined result was that sometimes the
functional versions of thread functions in pthread would not override
the weaks in libc.
While fixing this, I also prepended double-underscore to all necessary
weak thread funcs in uClibc, and removed all unused weaks.
I did a test build, but haven't tested this since these changes are
a backport from my working tree. I did test the changes there and
no longer need to explicitly add -lpthread in the perl build for
perl to pass its thread self tests.

Should be standards compliant and with several optional features,
including support for hexadecimal float notation, locale awareness,
glibc-like locale-specific digit grouping with the `'' flag, and
positional arg support. I tested it pretty well (finding several
bugs in glibc's scanf in the process), but it is brand new so be
aware.
The *wprintf functions now support floating point output. Also, a
couple of bugs were squashed. Finally, %a/%A conversions are
now implemented.
Implement the glibc xlocale interface for thread-specific locale
support. Also add the various *_l(args, locale_t loc_arg) funcs.
NOTE!!! setlocale() is NOT threadsafe! NOTE!!!
The strto{floating point} conversion functions are now locale aware.
The also now support hexadecimal floating point notation.
Add the wcsto{floating point} conversion functions.
Fix a bug in mktime() related to dst. Note that unlike glibc's mktime,
uClibc's version always normalizes the struct tm before attempting
to determine the correct dst setting if tm_isdst == -1 on entry.
Add a stub version of the libintl functions. (untested)
Fixed a known memory leak in setlocale() related to the collation data.
Add lots of new config options (which Erik agreed to sort out :-),
including finally exposing some of the stripped down stdio configs.
Be careful with those though, as they haven't been tested in a
long time.
(temporary) GOTCHAs...
The ctype functions are currently incorrect for 8-bit locales. They
will be fixed shortly.
The ctype functions are now table-based, resulting in larger staticly
linked binaries. I'll be adding an option to use the old approach
in the stub locale configuration.

Hopefully locale support will build when cross compiling now. Collation is
still not supported, but that's what I'm currently working on. In the
next couple of days, I'll probably put up a couple of files for download
that will save people the trouble of generating all the glibc locales.
Added *wprintf functions, although they currently don't support floating
point. That will be fixed when I rewrite _dtostr... or possibly before.
Added the wcsto{inttype} functions.
Added iconv() and a mini iconv utility. The require locale support and
only provide for conversions involving the various unicode encodings
{ UCS-4*, UCS-2*, UTF-32*, UTF-16*, UTF-8 }, the 8-bit codesets built
with the locale data, and the internal WCHAR_T.

when the grouping flag "'" is specified. Grouping for floating point values
may wait until I do a rewrite of the floating pt to string code...

been working on a new config system on and off for about 6 months
now, but I've never been fully satisfied. Well, I'm finally am
happy with the new config system, so here it is. This completely
removes the old uClibc configuration system, and replaces it with
an entirely new system based on LinuxKernelConf, from
http://www.xs4all.nl/~zippel/lc/
As it turns out, Linus has just merged LinuxKernelConf into Linux
2.5.45, so it looks like I made the right choice.
I have thus far updated only x86. I'll be updating the other
architectures shortly.

needlessly. To do so increases the generated code size with bcc.
Eliminate duplicate define warnings in wstring.c.
Fix potentially broken preprocessor comparisons. The preprocessor
converts integers to maximal signed type, so inequality comparisons
involving UINTMAX_MAX, ULLONG_MAX, and (if no long long) ULONG_MAX
were potentially broken.

Implemented unformatted wide i/o functions. (ungetwc still needs testing)
Fix a few bugs in wchar.c.
Modifications for bcc/elks support.

standards. Temporarily added a utility function to wrap Erik's strerror_r
so that "Unknown error xxx" strings can be generated for errno's which
cause strerror_r to fail. That utility function will eventually be merged
in with the strerror/strerror_r functions when I change over to optionallly
mmap'ing the system error strings to provide for lower mem comsumption on
non-MMU platforms, as well as locale-specific system error messages.
