Cygwin and Mingw name their libraries a bit differently from the rest
of the POSIXly universe, we need to adapt to that.

In Makefile.tmpl, it means that some hunks will only be output
conditionally.

This also means that shared_extension for the Cygwin and Mingw
configurations in Configurations/10-main.conf are changing from .dll.a
to .dll.  Makefile.shared does a fine job without having them
specified, and it's much easier to work with tucking an extra .a at
the end of files in the installation recipes than any amount of name
rewrites, especially with the support of the SHARED_NAME in the top
build.info.

This also adds all the raw sections needed for some files.

Under certain conditions, one might not want to output certain
sections of a template file.  This adds the functions output_off() and
output_on(), reachable inside the templates.  And example usage in a
Makefile template could be this:

	@ : {- output_off() if $config{no_shared}; "" -}
	... lines dealing with shared libraries
	@ : {- output_on() -}

The logic to figure out the combinations of --prefix and --openssldir
has stayed in Configure so far, with Unix paths as defaults.

However, since we're making Configure increasingly platform agnostic,
these defaults need to change and adapt to the platform, along with
the logic to combine them.

The easiest to provide for this is to move the logic and the defaults
away from Configure and into the build files.

This also means that the definition of the macros ENGINESDIR and
OPENSSLDIR move away from include/openssl/opensslconf.h and into the
build files.

Makefile.in is adapted accordingly.

With some compilers, C macros are defined differently on the command
line than on Unix.  It could be that the flad to define them isn't -D,
it could also be that they need to be grouped together and not be mixed
in with the other compiler flags (that's how it's done on VMS, for
example).

On Unix family platform configurations, we can continue to have macro
definitions mixed in with the rest of the flags, so the changes in
Configurations/*.conf are kept to an absolute minimum.

In build.info files, make the include directory in the build directory
absolute, or Configure will think it should be added to the source
directory top.  Configure will turn it into a relative path if
possible.

There were cases where some input was absolute, and concatenating it
to the diretory to the source or build top could fail spectacularly.
Let's check the input first to see if it's absolute.

And while we're on the subject of checking if a file or dir spec is
absolute using file_name_is_absolute() has its own quirks on VMS,
where a logical name is considered absolute under most circumstances.
This is perfectly correct from a VMS point of view, but when parsing
the build.info files, we want single word file or directory names to
only be checked syntactically.  A function isabsolute() that does the
right thing is the solution.
