5b2a5b84de Replace Lst_Find calls with LST_FOREACH loops. This helps in
constification und simplifies the code because the one-liner
predicates can be inlined into the code.

b24cc98851 Clean up include files and file including. Split nonints.h into pieces
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somewhat outdated).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).

ce24622080 Instead of dynamically allocating list heads allocated them statically
now that their size is only two pointers. This eliminates a lot of calls
to Lst_Init and from there to malloc together with many calls to
Lst_Destroy (in places where the list is obviously empty). This also
reduces the chance to leave a list uninitilized so we can remove more
NULL pointer checks and probably eliminates a couple of memory leaks.

bcb1f1f6f5 Get rid of the sequential access feature of the lists. This was used
only in a couple of places and all of them except for one were easily
converted to use Lst_First/Lst_Succ. The one place is compatibility
mode in job.c where the it was used to advance to the next command on
each invocation of JobStart. For this case add a pointer to the node to
hold the currently executed command.

4dcbfdf876 Constify the arguments to the list compare function. This temporarily

8345f29bee Change the algorithm that matches the builtin shells from the name keyword
of the .SHELL target. Formerly it used to select the shell with the
longest common trailing substring, so that bash would select sh, but pocsh
would select csh. Now an exact match is required so that specifying bash
without also giving a path and the other keywords will give an error.

6a1de54fc3 Constify the array of predefined shells. It turns out that we need two
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.

0083a3a1f9 Fix a very long-standing error in handling .SHELL targets: this target
uses the brk_string function to parse the line. That function uses static
storage for both the expanded string and the returned argv[] vector.
The JobParseShell function simply stored away pointers into this static
storage. On the next use of something like ${FOO:O} this storage would
get overwritten with fatal results.

This also allows us to make the shells[] array const bringing us one step
further in making make WARNS=4 ready.

eb0fa827fc Add code to enforce the paralleism count (-j N) for the entire tree
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.

24fe3160f6 Fix a (very) long standing bug in make (this has been there probably
from the beginning). Make used to handle all its interrupt-time stuff
directly from the signal handler, including calls to printf, accessing
global data and so on. This is of course wrong and could provoke a core
dump when interrupting make. Just set a flag in the signal handler and
do everything else from the main thread.

b04f4a45fc Remove the remote stuff from make. This actually never worked in our make
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.

0db0c04954 Implement POSIX's '+' flag for command lines. This flag causes a line
to be executed even when -n is given on the command line to make. This is
very handy for calls to submakes.

This is slightly changed from the original patch as obtained from NetBSD.
The NetBSD variant prints lines which have both '+' and '@' when -n
is specified. The commited version always obeys '@'.

Bump MAKE_VERSION so Makefiles can use this conditionally.

435bfdfa44 Remove efree(), it isn't used consistently enough to even pretend that it
might help on the systems it could possibly be used as a bandaid for.  In
fact, the only thing it's useful for is instrumenting free(3) calls, and in
that capacity, it's better served as a local patch, than a public wrapper.

d466dc0ec0 Convert make(1) to use ANSI style function declarations. Variable
documentation already adequatedly existed in the description in most
cases.  Where it did not, it was added.  If no documentation existed
beforehand, then none was added.  Some unused dummies for use in the
traversal functions were marked as __unused during the conversion.
Occasionally, local style fixes were applied to lines already being
modified or influenced.

Now make(1) should always build with WARNS=3.

a few stragglers, which I will take care of as soon as I can.  Mostly these
relate to the need-for-death-of some of the remote job code.
