lukem b48252f365 * use _DIAGASSERT() to check pointer arguments against NULL and file
descriptors against -1 (as appropriate).
* add actual checks which to detect stuff that would trigger_DIAGASSERT(),
  and attempt to return a sane error condition.
* knf some code
* remove some `register' decls.

the first two items result in the addition of code similar to the
following in various functions:

		_DIAGASSERT(path != NULL)
	#ifdef _DIAGNOSTIC
		if (path == NULL) {
			errno = EFAULT;
			return (-1);
		}
	#endif

itojun db0f8786bd if the list of name server on /etc/resolv.conf is in a
non-supported AF, try the next nameserver instead of abort.

This helps situations like:
- you write IPv6 nameserver into /etc/resolv.conf and
- run non-IPv6 kernel

itojun e24b45d811 IPv6 DNS transport support for resolver.
Now you can write
	nameserver 3ffe:0501:4819::42
in /etc/resolv.conf for DNS query over IPv6 network.
(the above address is alive as DNS server)

kleink 0b11c41974 Since these files are shared with parts of the BIND-4 userland (outside libc),
do the internal symbol renaming dance only if inside the libc build environment.

mrg 32f519716b - use an array MAXHOSTNAMELEN+1 size to hold hostnames
- ensure hostname from gethostname() is nul-terminated in all cases
- minor KNF
- use MAXHOSTNAMELEN over various other values/defines
- be safe will buffers that hold hostnames

jtc 43fa6fe319 If port provides __weak_alias(), provide an Standard C and POSIX pure
identifier namespace by renaming non standard functions and variables
such that they have a leading underscore.  The library will use those
names internally.  Weak aliases are used to provide the original names
to the API.

This is only the first part of this change.  It is most of the functions
which are implemented in C for all NetBSD ports.  Subsequent changes are
to add the same support to the remaining C files, to assembly files, and
to the automagically generated assembly source used for system calls.
When all of the above is done, ports with weak alias support should add
a definition for __weak_alias to <sys/cdefs.h>.
