This target doesn't work with current directory layout. Just make cscope
index all .c and .h files.
While we're at it: add cscope output files to .gitignore.

We do this by maintaining a mask (for each pid) giving the fds to be closed on exec. We wrap functions that close fds so that their close-on-exec bits can be cleared at that point.
This implementation may close the fds even if the execve operation ultimately fails.
*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.
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 *.
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.
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.
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.
This is a BSD-licensed poll() implementation by Brian M. Clapper. Its performance characteristics aren't as good as a "native" poll() would be, but this shouldn't be a problem in practice.
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.
Newer versions of libselinux has started linking against more libs.
Rather than continuing hardcoding things, switch to using pkg-config
to query for its dependencies.

The existing test .config files are moved to configs/ and renamed
to *_defconfig. 'make xyz_defconfig' will enable the
configuration in that specific file.
