Some Unix variants require shared libraries to have the execute

It's possible to have a very few rules for some directories and trust
that other patterns further along will take care of whatever is left.
.gitignore should therefore be loosely organised from least generic to
most generic, allowing things like this:

    # Keep any file with extensions, such as foo.c, bar.h, ...
    !/dir/*.*

    # ....

    # Remove all object files
    *.o
    *.obj

With this change, we implement some very generic rules for what will
and will not be ignored in the fuzz subdirectory, and truse that
patterns later on (such as *.o, *.obj, *.exe) will take care of
everything we didn't specifically specify for the fuzz subdirectory.

If application uses any of Windows-specific interfaces, make it
application developer's respondibility to include <windows.h>.
Rationale is that <windows.h> is quite "toxic" and is sensitive
to inclusion order (most notably in relation to <winsock2.h>).
It's only natural to give complete control to the application developer.

OpenSSL engines are tied to the OpenSSL shared library versions,
starting with OpenSSL 1.1.  We therefore need to install them in
directories which have the shared library version in it's name, to
easily allow multiple OpenSSL versions to be installed at the same
time.

For VMS, the change is a bit more involved, primarly because the top
installation directory was already versioned, *as well as* some of the
files inside.  That's a bit too much.  Version numbering in files is
also a bit different on VMS.  The engines for shared library version
1.1 will therefore end up in OSSL$INSTROOT:[ENGINES0101.'arch']

('arch' is the architecture we build for)

On VMS, it's customary to have a procedure to check that the software

The procedure added here is fairly simple, it checks that all
libraries are in place, that the header crypto.h is in place, and that
the command 'openssl version -a' runs without trouble.

We calculate the size required for the ServerKeyExchange message and then

2 bytes required for the signature algorithm and 2 bytes for the signature
length, i.e. we could overflow by 4 bytes. In reality this won't happen
because the buffer is pre-allocated to a large size that means it should be
big enough anyway.
