OpenBSD port related changes.
Fixes minor bug in pipe.
Missing macro leads to not calling some of protocol'scallbacks.
*BSD port added. (Tested on FreeBSD and NetBSD)
Autoconf is evil. The sysconfdir and similar variables are unusable inC includes as they contain substitutions specific to make.
Worked around by creating sysconf/paths.h which is created fromthe Makefile instead of by the configure script.
Configure PATH_CONTROL_SOCKET.autoconf.h is now written to obj/sysdep, the source tree is hopefullycompletely read-only now.
Use `struct ip_mreqn' instead of `struct ip_mreq' for multicastoperations on 2.1/2.2 kernels. This allows passing of real interfaceindexes instead of referencing interfaces by their IP addresses whichfails badly in presence of unnumbered interfaces.
Unfortunately, this structure is not visible with glibc 2.0 as it provides...
Use dmalloc instead of EFence when available (dmalloc has lot of improvementsover EFence and also hopefully smaller memory overhead, but sadly it's non-freefor commercial use).
If the DMALLOC_OPTIONS environment variable is not set, switch on `reasonable'...
First step of "autoconfization". Created a configure script whichguesses most system-dependent parameters and determines name of systemconfiguration file (sysdep/cf/...) with the remaining ones.
To compile BIRD, you now need to do:
autoconf # Create configure from configure.in...
