EVP_FETCH: deal with names without pre-defined NIDs

We didn't deal very well with names that didn't have pre-defined NIDs,
as the NID zero travelled through the full process and resulted in an
inaccessible method.  By consequence, we need to refactor the method
construction callbacks to rely more on algorithm names.

We must, however, still store the legacy NID with the method, for the
sake of other code that depend on it (for example, CMS).

Ignore entropy from RAND_add()/RAND_seed() in FIPS mode

The functions RAND_add() and RAND_seed() provide a legacy API which

ossl_bsearch(): New generic internal binary search utility function

OBJ_bsearch_ and OBJ_bsearch_ex_ are generic functions that don't
really belong with the OBJ API, but should rather be generic utility

Since crypto/stack/stack.c uses OBJ_bsearch_ex_, the stack API ends up
depending on the OBJ API, which is unnecessary, and carries along
other dependencies.

Therefor, a generic internal function is created, ossl_bsearch().

Allow specifying the tag after AAD in CCM mode

This change allows to pass the authentication tag after specifying

GCM and OCB also support to set the tag at any point before the call
to `EVP_*Final`, but this won't work for CCM due to a restriction
imposed by section 2.6 of RFC3610: The tag must be set before

Add a way for the application to get OpenSSL configuration data

OpenSSL_version(OPENSSL_DIR) gives you a nicely formatted string for
display, but if all you really want is the directory itself, you were
forced to parsed the string.

This introduces a new function to get diverse configuration data from
the library, OPENSSL_info().  This works the same way as
OpenSSL_version(), but has its own series of types, currently
including:

OPENSSL_INFO_CONFIG_DIR         returns OPENSSLDIR
OPENSSL_INFO_ENGINES_DIR        returns ENGINESDIR
OPENSSL_INFO_MODULES_DIR        returns MODULESDIR
OPENSSL_INFO_DSO_EXTENSION      returns DSO_EXTENSION

OPENSSL_INFO_DIR_FILENAME_SEPARATOR     returns directory/filename separator
OPENSSL_INFO_LIST_SEPARATOR             returns list separator

For scripting purposes, this also adds the command 'openssl info'.

Configure: make disabling stuff easier and safer

Disabling one thing may mean having to disable other things as well.
We already have a process to auto-disable things through cascading,
but that was under-used.

Making the cascading mechanism available through a function to be
called to disable stuff makes it more automatic, and helps us when we
forget how different disabling options affect others.

asn1parse: avoid double free

|str| was used for multiple conflicting purposes.  When using
'-strictpem', it's used to uniquely hold a reference to the loaded
payload.  However, when using '-strparse', |str| was re-used to hold
the position from where to start parsing.

So when '-strparse' and '-strictpem' are were together, |str| ended up
pointing into data pointed at by |at|, and was yet being freed, with
the result that the payload it held a reference to became a memory
leak, and there was a double free conflict when both |str| and |at|
were being freed.

The situation is resolved by always having |buf| hold the pointer to
the file data, and always and only use |str| to hold the position to
start parsing from.  Now, we only need to free |buf| properly and not
|str|.
