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'.

This adds the flag OPENSSL_MODULES_DIR for OpenSSL_version(), and the
flag '-m' for 'openssl version'.

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.

Now that ciphers may come from providers we need to make sure we ask the

ossl_method_store_cache_get() and ossl_method_store_cache_set() were
called with a NULL argument for store, which means no caching is
done.  Give them a real store instead.

Also, increment the refcount when we do get a method out of the cache.

|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|.
