Export the same variables from all innshellvars instances

[eagle]

The different implementations of innshellvars currently use different names for the same variables (SPOOLBASE, for example, in the shell version). We should standardize so that everyone uses the same name for the same thing and everyone exports the same variables.

This will break backward compatibility, so needs to be done in a major release.

• Sets umask.
• New variable $home.
• Export variables NEWSHOME, SPOOLDIR, MOST_LOGS, NEWSBIN, NEWSETC, NEWSLIB, INNDDIR, NEWSLBIN in the environment.
