been two maxJobs variables: one static in job.c and one global used in
main.c and parse.c. Makeing one global out of these was the wrong way
to fix the problem. Instead rename the global one to jobLimit and keep
maxJobs static in job.c.

that get included just where they are needed. All headers include the
headers that they need to compile (just with an empty .c file). Sort
includes alphabetically where apropriate and fix some duplicate commenting
for struct Job, struct GNode and struct Shell by removing one version and
inlining the comments into the structure declaration (the comments have been
somewhat outdated).
This patch does not contain functional changes (checked with md5).

versions of the structure definition for this: one with const char
pointers, because otherwise gcc won't let us initialize the fields with
constant strings, and one without the const, because we need to work
with the structure.
of submakes spawned during processing.
We create a fifo and stuff one character into it for each job we are
allowed to run. The name of the fifo is passed to child processes
in the MAKE_JOBS_FIFO environment variable.
A make which finds this variable on startup will open the fifo and
only spawn jobs when it managed to read a token from the fifo.
When the job completes a token is writen back to the fifo.
Slave make processes get one token for free: the one their parent
make got in order to run them. This makes the make processes
themselves invisible in the process counts.
The net effect is that "make -j 12 -s buildworld" will start at
most 12 jobs at the same time, instead of as previously up to
65 jobs would get started.
because the necessary files were not imported with the original import.
If somebody really needs it, there is still the devel/pmake port.
This is just the first step and removes just everything that is ifdef'ed out.
Otherwise the code is unchanged.

While here, fixed a bug in the .SHELL directive processing
when only the name= attribute is specified and no built-in
shell matches this name, causing null pointer dereference.

Unfortunately we cannot enable it yet because it panics the kernel
somewhere in kqueue.

really far too long. Let us try 100ms instead, if you have a PP200,
maybe that's even too long. This should speed up make -j# builds.
I wonder why SIGCHLD isn't used...
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
- Add the .PHONY, .PARALLEL, and .WAIT directives
- Added the -B and -m commandline flags
- misc. man page cleanups
- numerous job-related enhancements
- removed unused header file (bit.h)
- add util.c for functions not found in other envs.
- and a few coordinated whitespace changes

problems in the process:
1. Quoting should work properly now. In particular, Chet's reported bash
make problem has gone away.
2. A lot of memory that just wasn't being free'd after use is now freed.
This should cause make to take up a LOT less memory when dealing with
archive targets.
3. Give proper credit to Adam de Boor in a number of files.
