Define segments and make other adjustments in makefile. At this point, hush can successfully build and run, although it doesn't work correctly. The main Makefile is now dedicated to the GNO build. There's now a separate makefile for building on modern systems with GCC/Clang.

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.

shell/shell.common.c \
Add our own implementation of fnmatch (taken from NetBSD), because the one in GNO 2.0.6's libc is broken. The version in libc both matches things it shouldn't and doesn't match things it should, in (at least) cases where a pattern includes additional stuff beyond a *.

Set things up so hush can be build with debug code turned on. This involved breaking things up into more segments in debug mode, since the code is larger. I also had to remove some unused extern definitions, which were causing link errors when debug code was enabled. To enable debug code, pass "DEBUG=1" to make or build.gs.

Fix our handling of process groups for job control, working around a couple GNO bugs. *Most significantly, we avoid using setpgid(), because it doesn't work and in fact corrupts the kernel's process group table. *Also, work around tctpgrp() returning garbage instead of 0 on success. This adds an implementation of tcsetpgrp that works by reading the process tables to find a process in the appropriate group. This isn't used for the main job control operations, though, since it might be relatively slow. At this point, basic job control seems to work.

Add an emulation of waitpid that should be better than the one in libc. In particular, it will buffer information about children other than the one being waited for, so it isn't lost. It can also emulate a non-blocking wait by arranging to interrupt the wait with a signal.
