Add support for the ulimit syscall

Add in a MALLOC_GLIBC_COMPAT option to let people decide if they
want glibc style malloc(0) behavior

Add support for personality(), prctl(), ustat(), and ulimit()
syscalls, which had managed to stay unimplemented thus far.

Begin documenting differences between uClibc and SuSv3
-Erik

Patch from David Wuertele to prevent "conflicts with new declaration with C
linkage" problems with C++

Zou WeiJun noticed a type breaking the stime syscall
-Erik

Looks like I missed a spot

Shuffle options around a bit

Merge/rework config system per the latest from linux-2.6.0-test2
-Erik

For sparc, powerpc, mips, and alpha we should also use the
common ipc.h header and struct definitions.

Update inet_aton() to support an undocumented feature of inet_aton,
per UNIX Network Programming, Volume 1, second edition:

An undocumented feature of inet_aton is that if addrptr is
a null pointer, the function still performs it validation
of the input string, but does not store the result.

Update licensing discussion

Replace 'new' in a prototype to avoid c++ problems.

Fix a silly error.

To use the pregenerated locales, untar in the extra/locale directory.
Do a 'make config' or 'make menuconfig' in the uClibc root dir, then
a 'make headers' followed by 'make -C extra/locale pregen'. Then
continue with 'make' as usual.

Add a new *scanf implementation, includeing the *wscanf functions.
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.

Remove the arch specific shm.h and use the fixed up common
one which now uses the kernel structs
-Erik

Doing an search and replace on CFLAGS can prove dangerous. We don't
do -O0 by default anyways, so leave this disabled for now.

Bug fix from Peter Kjellerstedt <peter.kjellerstedt@axis.com>. vfscanf was
not setting the FILE bufread member to flag the end of the buffer.
Also, do not set bufgetc member if getc macro support is disabled.

Patch from Peter Kjellerstedt to not modify include/bits/sysnum.h
if it does not need to be updated.

Patch from Peter Kjellerstedt to make it simpler for arches to specify
either -fPIC or -fpic

Fix a silly cut-n-paste error

Yikes! This was doing another lock instead of unlocking the stream.

As noted by Felix Radensky back on 16 Mar:

I've tried several times to compile uClibc with soft-float
(both gcc-3.2.2 toolchain and wrapper), but applications
compiled with uClibc always failed with "Invalid instruction".
So I ended up disabling floating point at all and this works well.
I also has no problem with glibc from Monta Vista, which is
compiled with soft-float. My processor is PowerPC 405GP.

Maybe the problem is in FP() macro definition in
libc/sysdeps/linux/powerpc/setjmp.S and
libc/sysdeps/linux/powerpc/__longjmp.S

#ifdef __UCLIBC_HAS_FLOATS__
#define FP(x...) x
#else
#define FP(x...)
#endif

which should be defined as

if defined __UCLIBC_HAS_FLOATS__ && ! defined __UCLIBC_HAS_SOFT_FLOAT__
#define FP(x...) x
#else
#define FP(x...)
#endif

Only exec child apps if they are elf type ET_EXEC

Fix source code URL

oops. This is 0.9.20, not .30

More updates

Update note re binary compat

Update for release

Yield to yet another glibc-ism and add __progname
