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.

Relnotes:	yes
