cefa762ee5 Add interface to the scrypt KDF by means of PKEY_METHOD
Add an interface that allows accessing the scrypt KDF as a PKEY_METHOD.
This fixes #4021 (at least for the scrypt portion of the issue).

Changed HKDF to use EVP_PKEY_CTX_md() (review comment of @snhenson) and
introduced more specific error codes (not only indicating *that* some
parameter is missing, but actually *which* one it is).

a24a5b8cc4 More error handling to HKDF and one more case in TLS1-PRF
HKDF now handles an invalid digest like TLS1-PRF does (i.e., returns
KDF_R_INVALID_DIGEST if the passed digest is not known). Both KDFs now
set the error code KDF_R_UNKNOWN_PARAMETER_TYPE if a type was passed
that is not recognized. This will have the effect of improving debugging
output in case a user uses "openssl pkeyutl -kdf ..." in a wrong way and
result in an actual error code (instead of just "failure" and an empty
error stack).

48feaceb53 Remove the possibility to disable the UI module entirely
Instead, make it possible to disable the console reader that's part of
the UI module.  This makes it possible to use the UI API and other UI
methods in environments where the console reader isn't useful.

To disable the console reader, configure with 'no-ui-console' /
'disable-ui-console'.

'no-ui' / 'disable-ui' is now an alias for  'no-ui-console' /
'disable-ui-console'.

Fixes #3806

4c17819c41 Add internal functions to fetch PEM data from an opened BIO
store_attach_pem_bio() creates a STORE_CTX with the 'file' scheme
loader backend in PEM reading mode on an already opened BIO.
store_detach_pem_bio() detaches the STORE_CTX from the BIO and
destroys it (without destroying the BIO).

These two functions can be used in place of STORE_open() and
STORE_close(), and are present as internal support for other OpenSSL
functions.

Containers are objects that are containers for a bunch of other
objects with types we recognise but aren't readable in a stream.  Such
containers are read and parsed, and their content is cached, to be
served one object at a time.

This extends the FILE_HANDLER type to include a function to destroy
the cache and a function to simulate the EOF check.

This STORE module adds the following functionality:

- A function OSSL_STORE_open(), OSSL_STORE_load() and OSSL_STORE_close()
  that accesses a URI and helps loading the supported objects (PKEYs,
  CERTs and CRLs for the moment) from it.
- An opaque type OSSL_STORE_INFO that holds information on each loaded
  object.
- A few functions to retrieve desired data from a OSSL_STORE_INFO
  reference.
- Functions to register and unregister loaders for different URI
  schemes.  This enables dynamic addition of loaders from applications
  or from engines.

to deallocate resources. However, if we have never entered a function which

This commit ensures all such resources deallocated by these functions also
