Misc. fixes related to file handling:
...
*Use .null instead of /dev/null
*Account for GNO's dup2(), which non-standardly returns 0 on success
*Always call open with appropriate number of arguments
*Use STDIN_FILENO instead of (implicitly) 0

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.

Add synchronization to prevent the parent from running concurrently with the child until the child execs or terminates.
...
Our approach is to have the parent wait for SIGUSR2, and send that from the child just before it calls exec* or _exit.

Handle globals more simply, declaring the "G" structure containing them directly in shell/hush.c.
...
This allows the "G" struct to show up in the debugger, so it can easily be inspected.

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.

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.

Revise signal handling to work with GNO.
...
This involved using signal() rather than sigaction(), which GNO doesn't have. signal() doesn't have the signal-blocking feature of sigaction(), but I've tried to emulate it.

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.
