f21afe6360 ossl_rsa_sp800_56b_check_public: Be more lenient with small keys 
Fixes #13995

For small keys the MR test on the modulus can return
BN_PRIMETEST_COMPOSITE_WITH_FACTOR status although the modulus
is correct.

d4bf0d57a8 Flag RSA secret BNs as consttime on keygen and checks 
<https://github.com/openssl/openssl/pull/11765> switched the default
code path for keygen.

External testing through TriggerFlow highlighted that in several places
we failed (once more!) to set the `BN_FLG_CONSTTIME` flag on critical
secret values (either long term or temporary values).

This commit tries to make sure that the secret BN values inside the
`rsa struct` are always flagged on creation, and that temporary values
derived from these secrets are flagged when allocated from a BN_CTX.

8bf37709a4 Update RSA keygen to use sp800-56b by default 
Fixes #11742
Fixes #11764

The newer RSA sp800-56b algorithm is being used for the normal case of a non multiprime key of at least length 2048.
Insecure key lengths and mutltiprime RSA will use the old method.

Bad public exponents are no longer allowed (i.e values less than 65537 or even). Values such as 2 that would cause a infinite loop now result in an error. The value of 3 has been marked as deprecated but is still allowed for legacy purposes.

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.

Dr. Matthias St. Pierre
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.
