This fixes a bug introduced by ffbeac6b7d.
ClassInfo::subclassesFor() didn't previously throw an Exception if passed
an invalid class; it just returned no values. This will annoy minor-release
upgrades, and so I've made it return null instead in these situation.
Returns the table name for a field in a class hierarchy.
This issue raised itself with GridFieldSortableHeader not supporting sorting on fields from parent class fields.
Database abstraction broken up into controller, connector, query builder, and schema manager, each independently configurable via YAML / Injector
Creation of new DBQueryGenerator for database specific generation of SQL
Support for parameterised queries, move of code base to use these over escaped conditions
Refactor of SQLQuery into separate query classes for each of INSERT UPDATE DELETE and SELECT
Support for PDO
Installation process upgraded to use new ORM
SS_DatabaseException created to handle database errors, maintaining details of raw sql and parameter details for user code designed interested in that data.
Renamed DB static methods to conform correctly to naming conventions (e.g. DB::getConn -> DB::get_conn)
3.2 upgrade docs
Performance Optimisation and simplification of code to use more concise API
API Ability for database adapters to register extensions to ConfigureFromEnv.php
We know the subclass of a record by its ClassName value, but code changes
might have meant that class no longer exists. We used to just break,
but this patch overrides the apparent value of ClassName to be
one that exists in that situation
Config system used to provide an add_static_source method, which was intended for
use by Extensions to add statics. But extensions for a class arent initialised
until at least one instance of that class is created, so before that the
Config system didnt include values from extensions
This patch reverses the control flow, so that the Config system explictly asks
each Object for its additional config sources via the new method
get_extra_config_sources. This method returns an array that can contain
string names of classes and also raw associative arrays.
The developer visible change is that Extension#add_to_class has been
deprecated. Instead there is a new method, get_extra_config, which has
the same method signature but needs to guarantee that it doesnt
cause side effects. Additionally there is no need to call
parent::get_extra_config - this is handled automatically.
MINOR: Replaced usage of renamed classes with the new namespaced name.

API CHANGE: Moved the meat of SQLQuery's SQL generation into Database::sqlQueryToString(), to be overloaded by different database implementations.
API CHANGE: Moved the implementation of ClassInfo::hasTable() and ClassInfo::getValidSubClasses() into Database::hasTable() and Database::enumValuesForField(), to be overloaded by different database implementations.
