[PATCH] Fix strsep

[Jakub Jelinek <jakub at redhat dot com>]

Hi!

Recent bits/string2.h change broke strsep:
The problem is that outside of _LIBC there is no __strsep prototype.
Here is one possible patch (but I wonder why we actually need to export that
symbol from libc: __strsep macro could as well use
#if !defined _LIBC && defined (__USE_BSD)
#define __strsep_g(s, reject) strsep(s, reject)
#else
#define __strsep_g(s, reject) __strsep(s, reject)
#endif
#define __strsep .... __strsep_g(s, reject); ...
...
#ifdef __USE_BSD
# define strsep(s, reject) __strsep(s, reject)
#endif

I mean applications have no business to use __strsep and the code above
would ensure that apps outside of libc will use strsep@GLIBC_2.0, while
libc internally would use __strsep. This would have the advantage of
bypassing plt when calling the generic version of strsep, plus
__strsep@@GLIBC_2.2.5 symbol could be killed.
