No logic changes. Code size is the same too.

/etc/hosts and it has IPv4 address there.
The most common example is "127.0.0.1 localhost".
We don't want "ping localhost" to stall and time out on IPv6
queries to, say, inaccessible DNS server, right?

Thanks to Peter S. Mazinger for pointing out this (obvious) error.
The __ASSUME_NETLINK from ricardw's r22531 references a non-existing
variable in certain cases. I don't see how that could possibly work..

Some of the code is functionally identical before and after, but for now
I'm just mechanically reverting the entire mess.
|
|
For now, a straight revert; we can decide later wheter we want to do something
more.

definition. I seems to produce spurious warning:
libc/inet/resolv.c:1549: warning: 'visibility' attribute ignored on non-class types
(seems like gcc bug)
and it is not really needed - attribute_hidden was already
specified in function _declaration_ so it is not necessary here.
No code changes (verified with objdump).

we were closing a FILE, but did not record that fact by setting
a variable to NULL, and then we used it for reading!
While at it, small reduction in bss.

The obsolete functions bcopy, index, etc. are not supposed to be used within
uClibc itself. Hence, there is no libc_hidden_def for them, but the previous
patch did not just move libc_hidden_protos, it also added new ones for the
legacy functions. As a result, programs which use these functions can no
longer link with uClibc.
This fixes it by removing the unnecessary libc_hidden_protos. I've also
removed all inclusions of <strings.h> from uClibc source files: since we
define _GNU_SOURCE, it is sufficient to include <string.h>. We then do not
need to duplicate the libc_hidden_proto block in <strings.h>.

1. names with two consecutive dots are not valid
2. if name ends with a dot, dont try appending search domain(s)
alos a few small optimisations are here.

- Fixes _dl_exit()
- Implements sleep(3) for !UCLIBC_HAVE_REALTIME
- Implements usleep(3) for !UCLIBC_HAVE_REALTIME
- adds #warning about incorrect posix_fadvise{,64}()
- removes unused and unwanted uselib()
Net outcome is that an allnoconfig with HAVE_SHARED is now about 88k instead
of formerly 130k.

Also cleans up some stype inconsistensied and saves 2 bytes of rw data.
