The old behaviour was the perform variable expansion and globbing on the
output of both the variable expansion and globbing. Which allows some very
strange behaviour if, for example, globbed filenames contain $ symbols.
Unconditionally add new nodes from these expansions even if the names are
already children. The .WAIT code needs the order of children preserved.
Rename 'allsrc' to 'curSrcs' so that the variable passed to ParseDoSrc (etc)

messages whan make itself is suspended (ie by ^Z) before make actually
suspends, supress the messages during this sequence.
This means we don't care that they would be output after the suspend
and we can stop attempting to reap child status from withing the signal
handler (which doesn't work for recursive parallel makes).
The code simplification means that we can remove much of the code that
blocked signals - since the signal handlers (expect that for ^C and friends)
now do almost no work.
If there are any undead ones set a flag so we don't report the 'Child (pid)
not in table' message when they die - it is impossible to (portably) find
the childrens pids.
This happens when make is run as 'make -f- ... <<EOF' and the shell uses
a child of (what will be) make to write the data into a pipe.
- Send each type of signal to its own handler.
- Only call JobFinish when a process exits, in particular don't 'fake up'
'exitstatus' for jobs being continued, nor call it for suspends.
- When a job is stopped, use an entire variable to remember the fact, so
we know we need to send a SIGCONT. Don't change any other state.
- In order to report '*** [job3] Suspended' before we suspend ourselves we
have to call waitpid() from the signal handler - where we don't want to
process job termination events. Save the exit status and process later.
The code now handles:
- jobs that suspend themselves
- jobs exiting while suspended
- jobs that don't actually suspend at all

Instead of adding MAKE_BOOTSTRAP for hosted environments, i.e., when
you want things simple, instead add MAKE_NATIVE to get those hugely
important features like __RCSID().
It's now possible to build make on some hosts with: cc *.c */*.c
Notes:
* The immediately previous version of make errored out on --,
which is what needs fixing.
* Historic bsd make silently ate -- and continued to process
options, so this is a behavior change from that, too, but presumably
there is more to gain in fixing it than in being bug-compatible.
This makes it possible to use expressions like
${("${LIST:Msomething"}):?present:absent}
it also makes treatment of lhs and rhs more consistent, and
makes CondToken easier to read.
Update unit-test/cond1 to test new features.
