After reading Makefile and all the files that are included using .include
or .sinclude directives (source Makefiles) make considers each source
Makefile as a target and tries to rebuild it. Both explicit and implicit
rules are checked and all source Makefiles are updated if necessary. If
any of the source Makefiles were rebuilt, make restarts from clean state.
To prevent infinite loops the following source Makefile targets are
ignored:
- :: targets that have no prerequisites but have commands
- ! targets
- targets that have .PHONY or .EXEC attributes
- targets without prerequisites and without commands
When remaking a source Makefile options -t (touch target), -q (query
mode), and -n (no exec) do not take effect, unless source Makefile is
specified explicitly as a target in make command line.
Additionally, system makefiles and .depend are not considered as a
Makefiles that can be rebuilt.

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somewhat outdated).

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.

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.

to override @-prefixed commands in Makefiles. It is especially useful for
debugging ports and/or complex Makefiles in such a manner that is basically
a last resort, but is quite effective if the output is well-handled.

improve portability since we've lost portability in several other chunks

that -E only operates for a specified variable. Useful since the -e option
will often pull-in many unwanted variable overrides (esp. in a make world
situation). Uses include overriding BINOWN (which cannot be done by normal
methods or through abuses of MAKEFLAGS) or likely for ports to honour CFLAGS
(provided they're running on a system whose make(1) has this option).
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been

- 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

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.
