f520690c2c Rework the directive parsing code. Instead of using a lot of strcmp()s
on every line that starts with a dot use a minimal perfect hash
function and a single strcmp() on the first word after the dot
to find out whether it is really a directive call and, if yes, which
one. Then directly dispatch to a handler function for that directive
(or fall through to the dependency handling code). This makes the
directive parse a little bit more strict about the syntax: the directive
word must be followed by a character that is not alphanumerical and not
an underline (making .undefFOO illegal); .endif and .else can only be
followed by comments.

ba467ce430 Make the structure for handling the input stack local to the parse
module. The only module accessing it (the current line number) was the
condition module, so pass the current line number as a function argument.
Centralize the pushing of new input sources into one function
ParsePushInput() and rename the function handling the popping from ParseEOF()
to ParsePopInput(). Make the entire thing a little bit clearer, by holding
the current input source in the top element of the stack instead of
using extra variables for this. Use a type-safe intrusive list for the
input stack.

fb1dac11b4 Make paths an explicite datatype instead of using the generic Lst.
A Path is now a TAILQ of PathElements each of which just points to
a reference counted directory. Rename all functions dealing with Paths
from the Dir_ prefix to a Path_ prefix.

6ea1a0dc21 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.

ab9e1eb050 Convert several typedefs from beeing pointers to structs to be the structs
itself. This will ease constification (think of what 'const Ptr foo'
means if Ptr is a pointer to a struct).

7a2029bac2 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somewhat outdated).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).

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.

db7ce92a3c Constify the arguments to the list compare function. This temporarily
requires to make a copy of the filename in ReadMakefile and to duplicate
two small functions in suff.c. This hopefully will go away when everything
is constified.

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.

cbfcb39874 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.

4526ed6ffb 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.

1e3d8881cf Add empty default cases where they should be, remove non-local execution stuff
in compat.c which doesn't even have preprocessor-conditional-hidden support
code, and add a debugging statement where we might end up with a nil list
somehow, but where I doubt it.

First confirmed userland kill for Flexelint.

2dbb6cf1cb Make the DEBUGF() macro portable by (ugh) adding a Debug() function, which
is merely printf() but to stderr.  This takes care of the caveat which lead
to the use of a vararg macro -- getting everything to stderr.

cdba64071c Move common use of if (DEBUG(FOO)) printf... to DEBUGF(FOO, ...), using
variable length arguments to a macro.  Bump version as this makes DEBUG
statements *always* go to stderr rather than sometimes stdout.  There are
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.

Nearby stylistic nits and XXX added/fixed where appropriate.

c0d06fe463 Merge in NetBSD's changes to make(1). Changes include:
- 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

Special thanks to Christos Zoulas <christos@netbsd.org>

FreeBSD now only contains sccsid-related diffs. :)

9f574f9a90 Bring in a number of changes from NetBSD's make, fixing quite a few
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.
