The KEYMGMT libcrypto <-> provider interface currently makes a few
assumptions:
1. provider side domain parameters and key data isn't mutable. In
other words, as soon as a key has been created in any (loaded,
imported data, ...), it's set in stone.
2. provider side domain parameters can be strictly separated from the
key data.
This does work for the most part, but there are places where that's a
bit too rigid for the functionality that the EVP_PKEY API delivers.
Key data needs to be mutable to allow the flexibility that functions
like EVP_PKEY_copy_parameters promise, as well as to provide the
combinations of data that an EVP_PKEY is generally assumed to be able
to hold:
- domain parameters only
- public key only
- public key + private key
- domain parameters + public key
- domain parameters + public key + private key
To remedy all this, we:
1. let go of the distinction between domain parameters and key
material proper in the libcrypto <-> provider interface.
As a consequence, functions that still need it gain a selection
argument, which is a set of bits that indicate what parts of the
key object are to be considered in a specific call. This allows
a reduction of very similar functions into one.
2. Rework the libcrypto <-> provider interface so provider side key
objects are created and destructed with a separate function, and
get their data filled and extracted in through import and export.
(future work will see other key object constructors and other
functions to fill them with data)

The property query cache was not reference count aware and this could cause
problems if the property store removes an algorithm while it is being returned
from an asynchronous query. This change makes the cache reference count aware
and avoids disappearing algorithms.
A side effect of this change is that the reference counts are now owned by the
cache and store.

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.

If ossl_method_store_add() gets called with a method that already exists
(i.e. the store has one with matching provider, nid and properties), that
method should not be stored. We do this check inside ossl_method_store_add()
because it has all the locking required to do so safely.

Because this function affects the reference count on failure (the call
to impl_free() does this), it may as well handle incrementing it as
well to indicate the extra reference in the method store.

Properties are a sequence of comma separated name=value pairs. A name
without a corresponding value is assumed to be a Boolean and have the
true value 'yes'. Values are either strings or numbers. Strings can be
quoted either _"_ or _'_ or unquoted (with restrictions). There are no
escape characters inside strings. Number are either decimal digits or
'0x' followed by hexidecimal digits. Numbers are represented internally
as signed sixty four bit values.
Queries on properties are a sequence comma separated conditional tests.
These take the form of name=value (equality test), name!=value (inequality
test) or name (Boolean test for truth). Queries can be parsed, compared
against a definition or merged pairwise.
