build system: commit configure
Commit configure (as generated by autoconf 2.67-2 Debian i386) into
the repo and remove it from .gitignore.
This now means that, provided you don't want to modify configure.in,
you can build secnet from a git clone without autoconf installed and
without any worries about the autoconf version.
If you _do_ modify configure.in, the resulting changes to configure
will end up in the repo, just as previously changes to config.h.in
were committed too.
