Among the new features it attempts to support alternative init systems.

Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

MFV r296164:
Update openresolve to version 3.7.3 including:

* Save the initial working directory and change to it just before
running any scripts.
This avoids scripts putting files accidently where they shouldn't.
* Strip trailing dot from search and domain names.
* man page improvements.

According to resolvconf.conf(5) manpage and sources, there is no
'nameservers' option which used in examples in resolvconf.conf(5),
it spelled 'name_servers', so fix examples.

Merge from openresolv 3.4.4 in the vendor branch.
