1d614caea7 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.

21d15001f9 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.

1d66b1beec 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.

dd1fa6553d 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.

8460583b9f Make explicit that MAKEOBJDIRPREFIX and MAKOBJDIR must be set
as environment variables and should not be set on make's command
line. They happen to work accidentially as command line variables
too when none of the sub-makes wants to play games with them (because
make is putting command line variables into the environment and will
find them there later on). Makefile.inc1 wants to change
MAKEOBJDIRPREFIX. In this case one cannot set it on the command line.

d98bc4ce72 Put variable assignments from the command line into the MAKEFLAGS
variable as required by POSIX. This causes such variables to be
pushed into all sub-makes called by the make (except when the MAKEFLAGS
variable is explicitely changed in the sub-make's environment).
This makes them also mostly un-overrideable in sub-makes except on the
sub-make's command line. Therefor specifying 'make CC=icc' will cause
icc to be used as C compiler in all sub-makes no matter what the Makefiles
itself try to do to the CC variable.

This patch also corrects the handling of the MFLAGS variable. MFLAGS
contains all the command line flags but not the command line variable
assignments. The evaluation of the .MFLAGS or .MAKEFLAGS target now
changes both MFLAGS and MAKEFLAGS (they used to change MAKEFLAGS only).
Makefiles can use MFLAGS for their own purposes given that they do not
except MFLAGS to be undefined at the beginning and that they don't evaluate
.MFLAGS or .MAKEFLAGS. MFLAGS should be removed for POSIX compliance,
but it is unfortunately heavily used by the X makefiles.

This has been extensively tested by port builds (thanks to portmgr), new
worlds and kernels.

34c9c43931 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.

19a7439edd Fix handling of comments on .elif lines. The patch given in a followup
to the PR failed, because the line skipping function is actually called
from two places in the code to do quite different things (this should
be two functions probably): in a false .if to skip to the next line
beginning with a dot and to collect .for loops. In the seconds case we
should not skip comments, because they are actually harder to handle than
we need for the .if case and should defer this to the main code.

91540c5b62 Improve make's diagnostic of mistmatched .if-.endif. This patch is
slightly different from the patch in the PR. The problem is, that
make handles .if clauses inside false .if clauses simply by
counting them - it doesn't put them onto the conditional stack, nor even
parses them so we need an extra line number stack for these ifs.

7da1dd01e6 Change the handling of non-anchored global substitutions of the empty
string from a silent implicit non-global substitution to a non-silent
explicit fatal error. Archored substitutions are those containing '^'
or '$'.
The problem with changing the substitution to prevent an infinite
number of matches is that it doesn't provide the necessary feedback
to the user that there's a bug in the/a makefile. Reporting the bug
without making the condition fatal makes the feedback mostly useless
due to the way that make fails to prefix the error with program name,
makefile file name and line number information.
Note that global substitutions of the empty string anchored with '^'
(start of string) or '$' (end of string) do not cause an infinite
number of matches and are therefore not reported and hence are non-
fatal.
