Properties for implementation selection.
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.

+Properties are associated with algorithms and are used to select between different implementations dynamically.
+
+This implementation is based on a number of assumptions:
+
+* Property definition is uncommon. I.e. providers will be loaded and
+ unloaded relatively infrequently, if at all.
+
+* The number of distinct property names will be small.
+
+* Providers will often give the same implementation properties to most or
+ all of their implemented algorithms. E.g. the FIPS property would be set
+ across an entire provider. Likewise for, hardware, accelerated, software,
+ HSM and, perhaps, constant_time.
+
+* There are a lot of algorithm implementations, therefore property
+ definitions should be space efficient. However...
+
+* ... property queries are very common. These must be fast.
+
+* Property queries come from a small set and are reused many times typically.
+ I.e. an application tends to use the same set of queries over and over,
+ rather than spanning a wide variety of queries.
+
+* Property queries can never add new property definitions.
+
+
+Some consequences of these assumptions are:
+
+* That definition is uncommon and queries are very common, we can treat
+ the property definitions as almost immutable. Specifically, a query can
+ never change the state of the definitions.
+
+* That definition is uncommon and needs to be space efficient, it will
+ be feasible to use a hash table to contain the names (and possibly also
+ values) of all properties and to reference these instead of duplicating
+ strings. Moreover, such a data structure need not be garbage collected.
+ By converting strings to integers using a structure such as this, string
+ comparison degenerates to integer comparison. Additionally, lists of
+ properties can be sorted by the string index which makes comparisons linear
+ time rather than quadratic time - the O(n log n) sort cost being amortised.
+
+* A cache for property definitions is also viable, if only implementation
+ properties are used and not algorithm properties, or at least these are
+ maintained separately. This cache would be a hash table, indexed by
+ the property definition string, and algorithms with the same properties
+ would share their definition structure. Again, reducing space use.
+
+* A query cache is desirable. This would be a hash table keyed by the
+ algorithm identifier and the entire query string and it would map to
+ the chosen algorithm. When a provider is loaded or unloaded, this cache
+ must be invalidated. The cache will also be invalidated when the global
+ properties are changed as doing so removes the need to index on both the
+ global and requested property strings.
+
+
+The implementation:
+
+* property_lock.c contains some wrapper functions to handle the global
+ lock more easily. The global lock is held for short periods of time with
+ per algorithm locking being used for longer intervals.
+
+* property_string.c contains the string cache which converts property
+ names and values to small integer indices. Names and values are stored in
+ separate hash tables. The two Boolean values, the strings "yes" and "no",
+ are populated as the first two members of the value table. All property
+ names reserved by OpenSSL are also populated here. No functions are
+ provided to convert from an index back to the original string (this can be
+ done by maintaining parallel stacks of strings if required).
+
+* property_parse.c contains the property definition and query parsers.
+ These convert ASCII strings into lists of properties. The resulting
+ lists are sorted by the name index. Some additional utility functions
+ for dealing with property lists are also included: comparison of a query
+ against a definition and merging two queries into a single larger query.
+
+* property.c contains the main APIs for defining and using properties.
+ Algorithms are discovered from their NID and a query string.
+ The results are cached.
+
+ The caching of query results has to be efficient but it must also be robust
+ against a denial of service attack. The cache cannot be permitted to grow
+ without bounds and must garbage collect under-used entries. The garbage
+ collection does not have to be exact.
+
+* defn_cache.c contains a cache that maps property definition strings to
+ parsed properties. It is used by property.c to improve performance when
+ the same definition appears multiple times.

+
+=head1 DESCRIPTION
+
+OSSL_METHOD_STORE stores implementations of algorithms that can be queried using
+properties and a NID.
+
+ossl_method_store_init() initialises the implementation method store subsystem.
+
+ossl_method_store_cleanup() cleans up and shuts down the implementation method
+store subsystem
+
+ossl_method_store_new() create a new empty implementation method store.
+
+ossl_method_store_free() frees resources allocated to B<store>.
+
+ossl_method_store_add() adds the B<implementation> to the B<store> as an
+instance of the algorithm indicated by B<nid> and the property definition
+<properties>.
+The optional B<implementation_destruct> function is called when
+B<implementation> is being released from B<store>.
+
+ossl_method_store_remove() remove the B<implementation> of algorithm B<nid>
+from the B<store>.
+
+ossl_method_store_fetch() query B<store> for an implementation of algorithm
+B<nid> that matches the property query B<prop_query>.
+The result, if any, is returned in B<result>.
+
+ossl_method_store_set_global_properties() sets implementation method B<store>
+wide query properties to B<prop_query>.
+All subsequent fetches will need to meet both these global query properties
+and the ones passed to the fetch function.
+
+ossl_method_store_cache_get() queries the cache associated with the B<store>
+for an implementation of algorithm B<nid> that matches the property query
+B<prop_query>.
+The result, if any, is returned in B<result>.
+
+ossl_method_store_cache_set() sets a cache entry for algorithm B<nid> with the
+property query B<prop_query> in the B<store>.
+Future cache gets will return the specified <result>.
+
+=head1 RETURN VALUES
+
+ossl_method_store_new() a new method store object or B<NULL> on failure.
+
+ossl_method_store_free(), ossl_method_store_add(),
+ossl_method_store_remove(), ossl_method_store_fetch(),
+ossl_method_store_set_global_properties(), ossl_method_store_cache_get()
+and ossl_method_store_cache_set() return B<1> on success and B<0> on error.
+
+ossl_method_store_free() and ossl_method_store_cleanup() do not return values.
