Clean up PROJ mess

Niklas, you proposed that "proj9" be renamed to "proj", later in the
migration. I suggest a minor change. Keep "proj9" unchanged, and make
"proj" an alias for proj9, or whatever the macports mechanism is for that.
This means that current ports that need "proj9" explicitly in some way,
remain unaffected.
After that, always install future major versions as explicitly pinned;
"proj10", etc. "proj" gets updated too, but remains an alias or pointer
for "the latest version". Port devs will then have their choice of pinned
or unpinned version, whatever they think is best for their scenario.
Hopefully this will mean less work at each major version step for proj.
