util/perl/OpenSSL/Ordinals.pm: introduce a base version

The idea is that a base version is the minimum version that must be
assigned to all symbols.  The practical result is that, for any new
major release, the version number for all symbols will automatically
be bumped to the new release's version number, if necessary.

Refactor the computation of API version limits

Previously, the API version limit was indicated with a numeric version
number.  This was "natural" in the pre-3.0.0 because the version was
this simple number.

With 3.0.0, the version is divided into three separate numbers, and
it's only the major number that counts, but we still need to be able
to support pre-3.0.0 version limits.

Therefore, we allow OPENSSL_API_COMPAT to be defined with a pre-3.0.0
style numeric version number or with a simple major number, i.e. can
be defined like this for any application:

    -D OPENSSL_API_COMPAT=0x10100000L
    -D OPENSSL_API_COMPAT=3

Since the pre-3.0.0 numerical version numbers are high, it's easy to
distinguish between a simple major number and a pre-3.0.0 numerical
version number and to thereby support both forms at the same time.

Internally, we define the following macros depending on the value of
OPENSSL_API_COMPAT:

    OPENSSL_API_0_9_8
    OPENSSL_API_1_0_0
    OPENSSL_API_1_1_0
    OPENSSL_API_3

They indicate that functions marked for deprecation in the
corresponding major release shall not be built if defined.

Switch to MAJOR.MINOR.PATCH versioning and version 3.0.0-dev

We're strictly use version numbers of the form MAJOR.MINOR.PATCH.
Letter releases are things of days past.

The most central change is that we now express the version number with
three macros, one for each part of the version number:

    OPENSSL_VERSION_MAJOR
    OPENSSL_VERSION_MINOR
    OPENSSL_VERSION_PATCH

We also provide two additional macros to express pre-release and build
metadata information (also specified in semantic versioning):

    OPENSSL_VERSION_PRE_RELEASE
    OPENSSL_VERSION_BUILD_METADATA

To get the library's idea of all those values, we introduce the
following functions:

    unsigned int OPENSSL_version_major(void);
    unsigned int OPENSSL_version_minor(void);
    unsigned int OPENSSL_version_patch(void);
    const char *OPENSSL_version_pre_release(void);
    const char *OPENSSL_version_build_metadata(void);

Additionally, for shared library versioning (which is out of scope in
semantic versioning, but that we still need):

    OPENSSL_SHLIB_VERSION

We also provide a macro that contains the release date.  This is not
part of the version number, but is extra information that we want to
be able to display:

    OPENSSL_RELEASE_DATE

Finally, also provide the following convenience functions:

    const char *OPENSSL_version_text(void);
    const char *OPENSSL_version_text_full(void);

The following macros and functions are deprecated, and while currently
existing for backward compatibility, they are expected to disappear:

    OPENSSL_VERSION_NUMBER
    OPENSSL_VERSION_TEXT
    OPENSSL_VERSION
    OpenSSL_version_num()
    OpenSSL_version()

Also, this function is introduced to replace OpenSSL_version() for all
indexes except for OPENSSL_VERSION:

    OPENSSL_info()

For configuration, the option 'newversion-only' is added to disable all
the macros and functions that are mentioned as deprecated above.
