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.

Change tarball making procedure

Since recently, OpenSSL tarballs are produced with 'make tar' rather
than 'make dist', as the latter has turned out to be more troublesome
than useful.

The next step to look at is why we would need to configure at all to
produce a Makefile just to produce a tarball.  After all, the tarball
should now only contain source files that are present even without
configuring.

Furthermore, the current method for producing tarballs is a bit
complex, and can be greatly simplified with the right tools.  Since we
have everything versioned with git, we might as well use the tool that
comes with it.

Added: util/mktar.sh, a simple script to produce OpenSSL tarballs.  It
takes the options --name to modify the prefix of the distribution, and
--tarfile tp modify the tarball file name specifically.

openssl s_server: don't use sendto() with connected UDP socket

Fixes #7675

On macOS, if you call `connect()` on a UDP socket you cannot then
call `sendto()` with a destination, otherwise it fails with Err#56
('socket is already connected').

By calling `BIO_ctrl_set_connected()` on the wbio we can tell it
that the socket has been connected and make it call `send()` rather
than `sendto()`.

Travis CI: Use flake8 to find Python syntax errors or undefined names

CLA: trivial

In Travis CI, add a Python linting step that runs flake8 tests in Travis CI
to find syntax errors and undefined names. (http://flake8.pycqa.org)

__E901,E999,F821,F822,F823__ are the "_showstopper_" flake8 issues that can halt
the runtime with a SyntaxError, NameError, etc. Most other flake8 issues are
merely "style violations" -- useful for readability but they do not effect
runtime safety.

* F822: undefined name `name` in `__all__`
* F823: local variable name referenced before assignment

Add option to read pkeyopts interactively

This patch adds the ability to interactively enter passphrases for
the pkeyutl application. For example, you could use

$ openssl pkeyutl -kdf TLS1-PRF -kdflen 8 -pkeyopt md:md5
  -pkeyopt_passin secret -pkeyopt_passin seed

To have the "secret" and "seed" values read interactively from keyboard
(with hidden input). Alternatively, the pass phrase argument syntax is
also supported, e.g.:

$ openssl pkeyutl -kdf TLS1-PRF -kdflen 8 -pkeyopt md:md5
  -pkeyopt_passin secret:stdin -pkeyopt_passin seed:env:SEEDVAR

To have "secret" read from stdin and "seed" from the environment
variable SEEDVAR.

When libssl and libcrypto are compiled on Linux with "-rpath", but
