Wrap <ifaddrs.h>, <netinet/in.h>, and <netinet/if_ether.h> so internal
calls go direct and all the symbols are weak

Userland programs should include <errno.h> not <sys/errno.h>

this is all new code. copyright to downsj and myself who managed to
erradicate the old stuff.

use socklen_t where needed; henning pvalchev ok

new bindresvport() semantics that itojun, shin, jean-luc and i have agreed on, which will be happy for the future. bindresvport_sa() for sockaddr *, too. docs later..

in bindresvport(), if sin is non-NULL, example sin->sin_family for the actual family being processed

set sa_len too

rresvport_af() and bindresvport_af()

Remove dead code
Remove unused variables
Silence some warnings
lint(1) is your friend

Fix RCS ids
Make sure everything uses {SYS,}LIBC_SCCS properly

errno restore was reversed.

if (beer-tonight) test-before-commit();

only reset port-range if modified initially; if needed call getsockname

Reset port range if bind() fails.

Use new bind() kernel semantics.
