Don't hardcode lock-runlog file rotation, let it to logrotate() bundle
Fix out-of-tree builds

Had to generate (with sed) enterprise_extension.[ch] in source (not
object) directory, because of circular dependency madness. Add all
auto-generated files to CLEANFILES for proper make-clean.
Fix typo in "allowciphers" server control option parsing.
Don't register lock cleanup if WriteLock() failed.

This way we avoid spurious error messages on exit, from when trying to
clear the inexistent lock (minor annoyance seen in the past while
stress-killing cf-serverd).
Turn some "should not happen" comments to UnexpectedError().

Various small fixes/cleanups
Add convenience this.promise_dirname variable, with acceptance test.
Reformulating code to avoid nasty surprises

GCC emits a warning when a pointer of a certain type is reinterpreted
as something else and assigned. The potential issue is that GCC might
reorder the way the pointer is read/written because it might assume the
wrong type, therefore it is better to avoid such things.

Adding Version structure

This structure can be used to compare software versions. It is aimed
towards comparison of CFEngine versions.
It supports the following format:

major.minor.path.extra-build

The field 'extra' is never included in comparisons, it is only included for
compatibility with Windows systems.
