e4f3d93ec6 - s/ip_t/ipv4_t/g
- Add "salt" to the beginning of UDP packets. Replaces length field which
  is not useful anyway.

34f9e6cf2d - route.c is now used to determine destination
- flags are removed, since they were not used at all. Use options instead.
- indirectdata works now, tcponly almost...
- made functions that don't return useful information void

a56df1e06b - Allow ASN1 style keys to be in the config files.
Note: tinc ignores private key in the main config file, tinc.conf,
  because it should really be in a separate file.
- When generating new keys, check if name is known and by default append
  the public key to the host configuration file (otherwise rsa_key.pub).

a0f7af3ed7 New function read_rsa_public_key();
In net.c/setup_myself deleted old code to read the public key (which
is now implicitly read in together with the private key).

09260b43d1 Read the PEM file pointed to by the configuration directive
PrivateKey.  This means thatt he meaning of this variable has changed,
it no longer should contain the private key directly.

WARNING: This code is untested.

cf49b2c064 Another big & bad commit:
- Added some extra search functions to rbl routines
- Fix subnet_lookup()
- Reorder some syslog messages to make more sense
- daemon() is back
- Don't let scripts execute in parallel (gives race conditions, and
  anyway something MIGHT just be configured which is necessary for further
  execution of tinc itself)
- Accidently merged check_child() with execute_script().
- Small fixes

f8f1007bf4 Porting to SunOS 5.8:
- More #includes Linux doesn't seem to need
- Don't do unsetenv() on SunOS
- Use a replacement asprintf() in case the OS doesn't support it
It now compiles properly under SunOS.

f95cc86d0c Changed execution of tinc-up:
- Do not free() strings that have been putenv()d, see man page of the
  latter.
- Do not set IFNAME anymore, it appears that the ioctl to get the name of
  the interface does not work at all. Since it is set to NETNAME in case
  of tun/tap and it is known beforehand in case of ethertap, there is no
  need for it anyway... (though it would've simplified things).

698191fd2f - Prepended config_ to all configuration option names, because it confused
everything (including myself).

  packets.
