ed57f7f935 ERR: Implement the macros ERR_raise() and ERR_raise_data() and use them
The ERR_raise() macro uses a trick in C.  The following is permitted:

    #include <stdio.h>

    void first(void)
    {
        printf("Hello! ");
    }

    void foo(const char *bar)
    {
        printf("%s", bar);
    }

    int main()
    {
        /* This */
        (first(),foo)("cookie");
    }

ERR_raise_data() can be used to implement FUNCerr() as well, which
takes away the need for the special function ERR_put_func_error().

a94a3e0d91 Add basic EVP_KEYMGMT API and libcrypto <-> provider interface
The idea with the key management "operation" is to support the
following set of functionality:

- Key domain parameter generation
- Key domain parameter import
- Key domain parameter export

- Key generation
- Key import
- Key export
- Key loading (HSM / hidden key support)

With that set of function, we can support handling domain parameters
on one provider, key handling on another, and key usage on a third,
with transparent export / import of applicable data.  Of course, if a
provider doesn't offer export / import functionality, then all
operations surrounding a key must be performed with the same
provider.

This method also avoids having to do anything special with legacy
assignment of libcrypto key structures, i.e. EVP_PKEY_assign_RSA().
They will simply be used as keys to be exported from whenever they are
used with provider based operations.

This change only adds the EVP_KEYMGMT API and the libcrypto <->
provider interface.  Further changes will integrate them into existing
libcrypto functionality.

7ffbd7ca96 OSSL_PARAM helper functions.
Provide a number of functions to allow parameters to be set and
retrieved in a type safe manner.  Functions are provided for many
integral types plus double, BIGNUM, UTF8 strings and OCTET strings.

All of the integer functions will widen the parameter data as
required.  This permits a degree of malleability in the parameter
definition.  For example a type can be changed from a thirty two bit
integer to a sixty four bit one without changing application code.
Only four and eight byte integral sizes are supported here.

A pair of real functions are available for doubles.

A pair of functions is available for BIGNUMs.  These accept any sized
unsigned integer input and convert to/from a BIGNUM.

For each OCTET and UTF8 strings, four functions are defined.  This
provide get and set functionality for string and for pointers to
strings.  The latter avoiding copies but have other inherent risks.

Finally, some utility macros and functions are defined to allow
OSSL_PARAM definition arrays to be specified in a simple manner.
There are two macro and one function for most types.  The exception
being BIGNUM, for which there is one macro and one function.

3a63dbef15 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.

567db2c17d Add EVP_MAC API
We currently implement EVP MAC methods as EVP_PKEY methods.  This
change creates a separate EVP API for MACs, to replace the current
EVP_PKEY ones.

A note about this EVP API and how it interfaces with underlying MAC
implementations:

Other EVP APIs pass the EVP API context down to implementations, and
it can be observed that the implementations use the pointer to their
own private data almost exclusively.  The EVP_MAC API deviates from
that pattern by passing the pointer to the implementation's private
data directly, and thereby deny the implementations access to the
EVP_MAC context structure.  This change is made to provide a clearer
separation between the EVP library itself and the implementations of
its supported algorithm classes.

a8ca496ddb Split the scrypt and RSA-PSS into man3 and man7 pages
The scrypt and RSA-PSS documents were a mixture of section 3 and
section 7 material.  With pre-1.1.1 OpenSSL, this is understandable,
since we had a different directory layout.  With 1.1.1, we've moved to
the typical man-page directory layout, and the documents need to be
updated accordingly.

Also, the scrypt document contained a description of
EVP_PKEY_CTX_set1_pbe_pass(), which is a generic function rather than
an scrypt specific function, and therefore should be documented
separately.

NOTE: The getters do not resolv the version in case when the minimum or

calls back to 'rand_add(...)' calls by changing the signature as follows:

-int RAND_poll_ex(RAND_poll_fn cb, void *arg);
+int RAND_poll_ex(RAND_poll_cb rand_add, void *arg);

Changed the function typedef name to 'RAND_poll_cb' to emphasize the fact
that the function type represents a callback function.
