If a user does supply a IPv4 or IPv6 address
but force the other type with -4 or -6, give an error.
The patch also fix the special [::ffff:127.0.1]
address handling, it work now if you bind to this
address but only if you not force IPv6 only, it seems
that the kernel does not signal connections to a
IPv6 socket listen on [::ffff:127.0.0.1], if it was bound
IPv6 only.
I think we can live with it and do not need a special test
for this address.

This patch detects numeric address types to avoid unnecessary
warnings/errors. It also cleans up error printing to not print error
messages on stderr in the deamon case.

This patch fix a issue with numeric IPv6 addresses in the
tftpd -a address[:port] option.
Since IPv6 addresses use colon ':' in differnt counts itself, we cannot detect,
if the last colon is a seperator, so it is needed to put the IPv6 address into
square brackets, e.g. [2001:db8::1], so a optional port assignment is
unambiguous.
The patch also allows to specify numeric IPv6 addresses in other places enclosed
in [], but in these cases it accept these also without [].

Add support for IPv6 in the server and client.
You can force the use of IPv4 or IPv6 only with new
-4 and -6 commandline options, if IPv6 support was compiled in.

On older systems, htonl() returns unsigned long, on newer systems it
returns uint32_t. Cast to unsigned long and use %08lX for the format,
that seems to be the easiest solution.
... because the signal handling code is enclosed in "#ifdef HAVE_REGEX"
instead of "#ifdef WITH_REGEX"
The following patch against head of "network/tftp/tftp-hap.git" on "kernel.org"
fixes this issues (you are using blanks for indention and not tabs. right?).
