Move all the source files to 15-character ProDOS-compatible file names.
...
Dmake gets confused if you use over-15-character file names, so they needed to be shortened to get it to work. While I was at it, I also switched _ to . in the filenames so they're fully ProDOS compatible.
The shell/hush_test directory (not needed to build the code) still uses ProDOS-incompatible file names.

GNO doesn't actually implement glob, although it has a header for it. The GNO header is from an old BSD version and is missing some constants we need, so don't use it.
