c3a4fa4cb8 Added internal functions for easy getting and setting all RSA parameters.
rsa_set0_all_params() is used to set all the primes, exponents and
coefficients.  rsa_get0_all_params() is used to get all the primes,
exponents and coefficients.

"All" includes p, q, dP, dQ and qInv without making them separate.

All arrays of numbers are implemented as stacks to make dynamic use
easier.

ae4186b004 Fix header file include guard names
Make the include guards consistent by renaming them systematically according
to the naming conventions below

For the public header files (in the 'include/openssl' directory), the guard
names try to match the path specified in the include directives, with
all letters converted to upper case and '/' and '.' replaced by '_'. For the
private header files files, an extra 'OSSL_' is added as prefix.

706457b7bd Reorganize local header files
Apart from public and internal header files, there is a third type called
local header files, which are located next to source files in the source
directory. Currently, they have different suffixes like

  '*_lcl.h', '*_local.h', or '*_int.h'

This commit changes the different suffixes to '*_local.h' uniformly.

25f2138b0a Reorganize private crypto header files
Currently, there are two different directories which contain internal
header files of libcrypto which are meant to be shared internally:

While header files in 'include/internal' are intended to be shared
between libcrypto and libssl, the files in 'crypto/include/internal'
are intended to be shared inside libcrypto only.

To make things complicated, the include search path is set up in such
a way that the directive #include "internal/file.h" could refer to
a file in either of these two directoroes. This makes it necessary
in some cases to add a '_int.h' suffix to some files to resolve this
ambiguity:

  #include "internal/file.h"      # located in 'include/internal'
  #include "internal/file_int.h"  # located in 'crypto/include/internal'

This commit moves the private crypto headers from

  'crypto/include/internal'  to  'include/crypto'

As a result, the include directives become unambiguous

  #include "internal/file.h"       # located in 'include/internal'
  #include "crypto/file.h"         # located in 'include/crypto'

hence the superfluous '_int.h' suffixes can be stripped.

The files 'store_int.h' and 'store.h' need to be treated specially;
they are joined into a single file.

0cd1b144f9 util/mkerr.pl: make it not depend on the function code
The output C code was made to use ERR_func_error_string() to see if a
string table was already loaded or not.  Since this function returns
NULL always, this check became useless.

Change it to use ERR_reason_error_string() instead, as there's no
reason to believe we will get rid of reason strings, ever.

To top it off, we rebuild all affected C sources.

9bcc9f973b Ensure RSA PSS correctly returns the right default digest
A default digest of SHA256 was being returned for RSA PSS even if the
PSS parameters indicated a different digest must be used. We change this
so that the correct default digest is returned and additionally mark this
as mandatory for PSS.

This bug had an impact on sig alg selection in libssl. Due to this issue
an incorrect sig alg might be selected in the event that a server is
configured with an RSA-PSS cert with parameter restrictions.

fcd2d5a612 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.

97b0b713fb RSA security bits calculation
NIST has updated their guidelines in appendix D of SP 800-56B rev2 (draft)
providing a formula for the number of security bits it terms of the length
of the RSA key.

This is an implementation of this formula using fixed point arithmetic.
For integers 1 .. 100,000 it rounds down to the next smaller 8 bit strength
270 times.  It never errs to the high side.  None of the rounded values occur
near any of the commonly selected lengths.
