14da3b8a1f ip/tinc: honor TcpOnly and IndirectData settings, script support, prefer incoming udp connections
only try listen/dial on udp when IndirectData/TcpOnly is not
enabled.

add support for scipts:
 host-up
 host-down
 tinc-up
 tinc-down
 subnet-up
 subnet-down

when dialing udp connection, only switch when there is no
other udp connection active. when we receive an authenticated
message, we switch to that connection immidiately.

a1fceabd5b devip: fix fragment forwarding
unfraglen() had the side effect that it would always copy the
nexthdr field from the fragment header to the previous nexthdr
field. this is fine when we reassemble packets but breaks
fragments that we want to just forward unchanged.

fa97c3dd10 devip: simplify ip reassembly functions, getting rid of Ipfrag.hlen
given that we now keep the block size consistent with the
ip packet size, the variable header part of the ip packet
is just: BLEN(bp) - fp->flen == fp->hlen.

fix bug in ip6reassemble() in the non-fragmented case:
reload ih after ip header was moved before writing ih->ploadlen.

use concatbloc() instead of pullupblock().

5b972a9aea devip: fix ip fragmentation handling issues with header options
some protocols assume that Ip4hdr.length[] and Ip6hdr.ploadlen[]
are valid and not out of range within the block but this has
not been verified. also, the ipv4 and ipv6 headers can have variable
length options, which was not considered in the fragmentation and
reassembly code.

to make this sane, ipiput4() and ipiput6() now verify that everything
is in range and trims to block to the expected size before it does
any further processing. now blocklen() and Ip4hdr.length[] are conistent.

ipoput4() and ipoput6() are simpler now, as they can rely on
blocklen() only, not having a special routing case.

ip fragmentation reassembly has to consider that fragments could
arrive with different ip header options, so we store the header+option
size in new Ipfrag.hlen field.

unfraglen() has to make sure not to run past the buffer, and hadle
the case when it encounters multiple fragment headers.

0aac600fb3 lib9p: fix zero msize abort() due to unknown version (thanks kivik)
kivik wrote:

I've found a nasty bug in lib9p handling of Tversion
messages, where an invalid version string in the request
leads to servers abort()ing the spaceship.

To reproduce:
	; ramfs -S ram
	; aux/9pcon /srv/ram
	Tversion ~0 DIE

The issue lies in sversion() where in case an invalid
version string is received we respond right away with
ofcall.version="unknown"; however, we fail to set the
ofcall.msize, which at this point is cleared to 0.  This
causes the convS2M call in respond() to fail and abort being
called.
