Rearrange source tree to be directly usable by dependants

This allows the LV2 source distribution to be used as an include path for
compilers and an LV2_PATH for applications, at the expense of self-contained
bundles.  That's a nice idea, but it made LV2 itself weird and annoying to
depend on.  This rearranges things so that directories in the source tree
correspond more closely to installation directories.

To make this possible, the "aux" directory in the documentation output has been
changed to "style", to avoid the reserved name "aux" on Windows.

+	lv2:documentation """
+
+LV2 is an interface for writing audio plugins in C or compatible languages,
+which can be dynamically loaded into many _host_ applications.  This core
+specification is simple and minimal, but is designed so that _extensions_ can
+be defined to add more advanced features, making it possible to implement
+nearly any feature.
+
+LV2 maintains a strong distinction between code and data.  Plugin code is in a
+shared library, while data is in a companion data file written in
+[Turtle](https://www.w3.org/TR/turtle/).  Code, data, and any other resources
+(such as waveforms) are shipped together in a bundle directory.  The code
+contains only the executable portions of the plugin.  All other data is
+provided in the data file(s).  This makes plugin data flexible and extensible,
+and allows the host to do everything but run the plugin without loading or
+executing any code.  Among other advantages, this makes hosts more robust
+(broken plugins can't crash a host during discovery) and allows generic tools
+written in any language to work with LV2 data.  The LV2 specification itself is
+distributed in a similar way.
+
+An LV2 plugin library is suitable for dynamic loading (for example with
+`dlopen()`) and provides one or more plugin descriptors via `lv2_descriptor()`
+or `lv2_lib_descriptor()`.  These can be instantiated to create plugin
+instances, which can be run directly on data or connected together to perform
+advanced signal processing tasks.
+
+Plugins communicate via _ports_, which can transmit any type of data.  Data is
+processed by first connecting each port to a buffer, then repeatedly calling
+the `run()` method to process blocks of data.
+
+This core specification defines two types of port, equivalent to those in
+[LADSPA](http://www.ladspa.org/), lv2:ControlPort and lv2:AudioPort, as well as
+lv2:CVPort which has the same format as an audio port but is interpreted as
+non-audible control data.  Audio ports contain arrays with one `float` element
+per sample, allowing a block of audio to be processed in a single call to
+`run()`.  Control ports contain single `float` values, which are fixed and
+valid for the duration of the call to `run()`.  Thus the _control rate_ is
+determined by the block size, which is controlled by the host (and not
+necessarily constant).
+
+### Threading Rules
+
+To facilitate use in multi-threaded programs, LV2 functions are partitioned into
+several threading classes:
+
+| Discovery Class                  | Instantiation Class           | Audio Class                    |
+|----------------------------------|-------------------------------|------------------------------- |
+| lv2_descriptor()                 | LV2_Descriptor::instantiate() | LV2_Descriptor::run()          |
+| lv2_lib_descriptor()             | LV2_Descriptor::cleanup()     | LV2_Descriptor::connect_port() |
+| LV2_Descriptor::extension_data() | LV2_Descriptor::activate()    |                                |
+|                                  | LV2_Descriptor::deactivate()  |                                |
+
+Hosts MUST guarantee that:
+
+ * A function in any class is never called concurrently with another function
+   in that class.
+
+ * A _Discovery_ function is never called concurrently with any other function
+   in the same shared object file.
+
+ * An _Instantiation_ function for an instance is never called concurrently
+   with any other function for that instance.
+
+Any simultaneous calls that are not explicitly forbidden by these rules are
+allowed. For example, a host may call `run()` for two different plugin
+instances simultaneously.
+
+Plugin functions in any class MUST NOT manipulate any state which might affect
+other plugins or the host (beyond the contract of that function), for example
+by using non-reentrant global functions.
+
+Extensions to this specification which add new functions MUST declare in which
+of these classes the functions belong, define new classes for them, or
+otherwise precisely describe their threading rules.

+
+Hosts may present CV ports to users as controls in the same way as control

+
+In particular, this port type does not imply any range, unit, or meaning for

+
+This, along with lv2:microVersion, is used to distinguish between different

+the most recent version of a plugin.  An LV2 version has a minor and micro
+number with the usual semantics:
+
+  * The minor version MUST be incremented when backwards (but not forwards)
+    compatible additions are made, for example the addition of a port to a
+    plugin.
+
+  * The micro version is incremented for changes which do not affect
+    compatibility at all, for example bug fixes or documentation updates.
+
+Note that there is deliberately no major version: all versions with the same
+URI are compatible by definition.  Replacing a resource with a newer version of
+that resource MUST NOT break anything.  If a change violates this rule, then
+the URI of the resource (which serves as the major version) MUST be changed.
+
+Plugins and extensions MUST adhere to at least the following rules:
+
+  * All versions of a plugin with a given URI MUST have the <q>same</q> set of
+    mandatory (not lv2:connectionOptional) ports with respect to lv2:symbol and
+    rdf:type.  In other words, every port on a particular version is guaranteed
+    to exist on a future version with same lv2:symbol and at least those
+    rdf:types.
+
+  * New ports MAY be added without changing the plugin URI if and only if they
+    are lv2:connectionOptional and the minor version is incremented.
+
+  * The minor version MUST be incremented if the index of any port (identified
+    by its symbol) is changed.
+
+  * All versions of a specification MUST be compatible in the sense that an
+    implementation of the new version can interoperate with an implementation
+    of any previous version.
+
+Anything that depends on a specific version of a plugin (including referencing
+ports by index) MUST refer to the plugin by both URI and version.  However,
+implementations should be tolerant where possible.
+
+When hosts discover several installed versions of a resource, they SHOULD warn
+the user and load only the most recent version.
+
+An odd minor _or_ micro version, or minor version zero, indicates that the
+resource is a development version.  Hosts and tools SHOULD clearly indicate
+this wherever appropriate.  Minor version zero is a special case for
+pre-release development of plugins, or experimental plugins that are not
+intended for stable use at all.  Hosts SHOULD NOT expect such a plugin to
+remain compatible with any future version.  Where feasible, hosts SHOULD NOT
