6861248dfc None of the users of Buf_Discard used it to get rid of only a part of
the buffer. So replace Buf_Discard by Buf_Clear which just gets rid
of the entire contents.

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somewhat outdated).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).

ebeffbcdeb Remove all the cleanup functions. There is no reason to free memory
just before exiting (especially given the number of memory leaks) -

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.

328c4c7fce Put variable assignments on .MAKEFLAGS and .MFLAGS targets into
the .MAKEFLAGS variable so that these are also passed to sub-makes.
This makes the handling of variables in the command environment more
consistent.

fbcc82e0b7 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.

c97b10a2a8 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.

f9f65ee8ce Prevent infinite substitution of the empty string by forcing non-
global substitution. In general it's a makefile bug to globally
substitute the empty string, but it's a bug in make(1) if a bug
in the makefile yields an infinite running time of make(1).

5c2d1427fb Convert some broken cases where Error is called, but we try to continue,
to Fatal errors, because the logic that we use to try to continue is far
too broken, and makes things look and act weird, because we end up pointing
past the end of a buffer boundry into freed memory in the caller, as we
don't come close to setting the lengthPtr to a sane value.

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.

21a07813ec Make make(1) WARNS=6 clean except for const issues. This mostly involves

The only thing I'd still like to do WRT this is possibly combine rstat and
status in compat.c -- that should be fine, as I do not think the codepaths
will want both around at once.

1b7c0a19e3 make(1) claims to ignore the remainder of a conditional once its value
has been determined similar to C. That is, one expects a construction
like,

.if defined(TEST) && (${TEST:L} == "test")

Never to generate an error since the second expression should never be
evaluated when TEST is undefined.

However, this was not the case. The above fails with the current
make(1) if TEST is undefined. This patch fixes the above and many
similar cases.
