This ensures that only one set of includes is associated with each
object file, reagardless of where it's used.
For example, if apps/build.info has this:
SOURCE[openssl]=foo.c
INCLUDE[openssl]=.. ../include
and test/build.info has this:
SOURCE[footest]=../apps/foo.c
INCLUDE[footest]=../include
The inclusion directories used for apps/foo.o would differ depending
on which program's dependencies get generated first in the build file.
With this change, all those INCLUDEs get combined into one set of
inclusion directories tied to the object file.

Remove some config attributes that just duplicate values that are
already there in other attributes.
Remove the special runs of mkdef.pl and mkrc.pl from build file
templates, as these are now done via GENERATE statements in
build.info.
Remove all references to ordinal files from build file templates, as
these are now treated via the GENERATE statements in build.info.
Also remove -shared flags and similar that are there in shared-info.pl
anyway. (in the case of darwin, it's mandatory, as -bundle and

Because this also includes handling all sorts of non-object files when
linking a program, shared library or DSO, this also includes allowing
general recognition of files such as .res files (compiled from .rc
files), or .def / .map / .opt files (for export and possibly
versioning of public symbols only).
This does mean that there's a tangible change for all build file
templates: they must now recognise and handle the `.o` extension,
which is used internally to recognise object files internally. This
extension was removed by common.tmpl before this change, but would
mean that the platform specific templates wouldn't know if "foo.map"
was originally "foo.map.o" (i.e. an object file in its own right) or
"foo.map" (an export definition file that should be treated as such,
not as an object file).
For the sake of simplifying things, we also modify util/mkdef.pl to
produce .def (Windows) and .opt (VMS) files that don't need additional
hackery.

when building shared libraries, as there is not static library then,

Send a bit information to the build file template functions. For
src2obj(), the additional option 'product' holds the name of the final
file that the object file will go into. Additionally, the diverse
functions will get the option 'installed', with a value that evaluates
true if the final product is to be installed, otherwise false.

'DEPEND[]=file.h' becomes a special way to say that 'file.h' must be
generated before anything else is built. It's likely that a number
of source files depend on these header files, this provides a simple
way to make sure they are always generated even it the dependency data
hasn't been added to the build file yet.

The directories for the final products were never registered, it was
plain luck that intermediary files were in the same place and
registered the directory anyway.
Also, scripts are generated directly from source (binaries go through
intermadiary object files), so we need to explicitely make sure to
avoid registering the source directory unless it's an in source
build.

Previous build scheme allowed building just the stuff in one
subdirectory, like this:
make -C crypto/aes
Because the unified only has a top-level Makefile, this is not
possible with it. This change adds a replacement where each directory
we have something to build in becomes a target in its own right,
allowing building something like this:
make crypto/aes
The exception is the directory test, because we already have such a
target.

In the case of generating a file like this:
GENERATE[foo.S]=mkfoo.pl arg1 arg2
the 'mkfoo.pl' generator itself might need to include other files,
such as perl modules within our source tree. We can reuse already
existing syntax for it, like this:
INCLUDE[mkfoo.pl]=module/path
or:
DEPEND[mkfoo.pl]=modules/mymodule.pm
This change implements the support for such constructs, and for the
DEPEND statement, for any value that indicates a perl module (.pm
file), it will automatically infer an INCLUDE statement for its
directory, just like it does for C header files, so you won't have do
write this:
DEPEND[mkfoo.pl]=modules/mymodule.pm
INCLUDE[mkfoo.pl]=modules

Should it be needed because the recipes within a RAW section might

In some cases, one might want to generate some source files from
others, that's done as follows:
GENERATE[foo.s]=asm/something.pl $(CFLAGS)
GENERATE[bar.s]=asm/bar.S
The value of each GENERATE line is a command line or part of it.
Configure places no rules on the command line, except the the first
item muct be the generator file. It is, however, entirely up to the
build file template to define exactly how those command lines should
be handled, how the output is captured and so on.

This takes us away from the idea that we know exactly how our static
libraries are going to get used. Instead, we make them available to
build shareable things with, be it other shared libraries or DSOs.
On the other hand, we also have greater control of when the shared
library cflags. They will never be used with object files meant got
binaries, such as apps/openssl or test/test*.
With unified, we take this a bit further and prepare for having to
deal with extra cflags specifically to be used with DSOs (dynamic
engines), libraries and binaries (applications).

.d (.MMS in the VMS world) files with just dependencies are built from
exactly the same conditions as the object files. Therefore, the rules
for them can be built at the same time as the rules for the
corresponding object files.
This removes the requirement for a src2dep function in the build file
templates, and for common.tmpl to call it. In the end, the existence

There was a catch 22, where 'make depend' directly after configuring
