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.

The current code implements the 'm' modifier only for 's'
conversions and would cause a segfault if it was used for 'c'
or '[' conversions. This patch extends the code to cover these
cases too.
The original version could write scanned data outside the passed buffer
because index i used in the '[' conversion handling block was clobbered.

We found that the testcase
int
main (void)
{
wchar_t s[10];
memset (s, 0, sizeof (s));
int r = sscanf ("s", "%ls", s);
printf ("%d\n", r);
printf ("%ls\n", s);
return 0;
}
printed
0
<blankline>
rather than the expected
1
s
The problem was the enum in _scanf.c, which has had a 'CONV_m' value
inserted. The attached patch fixes the problem in __psfs_parse_spec by
not presuming a particular displacement between the two sets of
char-like conversion values. With this patch the above program produces
the expected output.

This drops __signed, __volatile, and __const. Only the latter was
used in the code base, and for uClibc, not consistently. Much of
the code used plain "const" which meant "__const" was useless.
Really, the point of this is to stay in sync with what glibc did.

This matches a similar change made to glibc.
No functional changes here.

The latest POSIX spec introduces a "m" character to allocate buffers for
the user when using scanf type functions. This is like the old glibc "a"
flag, but now standardized. With packages starting to use these, we need
to implement it.
for example:
char *s;
sscanf("foo", "%ms", &s);
printf("%s\n", s);
free(s);
This will automatically allocate storage for "s", read in "foo" to it,
and then display it.
I'm not terribly familiar with the stdio layer, so this could be wrong.
But it seems to work for me.

is always equivalent to __UCLIBC_CURLOCALE->x.
remove typedef __uclibc_locale_t, it used only in a few places,
it is lees confusing to use struct __uclibc_locale_struct
everywhere.
xlocale.h: hide __global_locale back under _LIBC,
bug 53 is wrong in claiming it should be exported.
Also hide under _LIBC:
extern __locale_t __curlocale_var;
extern __locale_t __curlocale(void);
extern __locale_t __curlocale_set(__locale_t newloc);
# define __UCLIBC_CURLOCALE
# define __XL_NPP(N)
# define __LOCALE_PARAM
# define __LOCALE_ARG
# define __LOCALE_PTR

code-size wise).

libc/inet/ethers.c __ether_line_w() function.
I will wait for fallout reports for a week or so,
then continue converting more libc_hidden_proto's.
