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.

+
+This specification defines a data type for a MIDI message, midi:MidiEvent,
+which is normalised for fast and convenient real-time processing.  MIDI is the
+<q>Musical Instrument Digital Interface</q>, a ubiquitous binary standard for
+controlling digital music devices.
+
+For plugins that process MIDI (or other situations where MIDI is sent via a
+generic transport) the main type defined here, midi:MidiEvent, can be mapped to
+an integer and used as the type of an LV2 [Atom](atom.html#Atom) or
+[Event](event.html#Event).
+
+This specification also defines a complete vocabulary for the MIDI standard,
+except for standard controller numbers.  These descriptions are detailed enough
+to express any MIDI message as properties.
+

+midi:MidiEvent
+	lv2:documentation """
+
+A single raw MIDI message (a sequence of bytes).
+
+This is equivalent to a standard MIDI messages, except with the following
+restrictions to simplify handling:
+
+  * Running status is not allowed, every message must have its own status byte.
+
+  * Note On messages with velocity 0 are not allowed.  These messages are
+    equivalent to Note Off in standard MIDI streams, but here only proper Note
+    Off messages are allowed.
+
+  * "Realtime messages" (status bytes 0xF8 to 0xFF) are allowed, but may not
+     occur inside other messages like they can in standard MIDI streams.
+
+  * All messages are complete valid MIDI messages.  This means, for example,
+    that only the first byte in each event (the status byte) may have the
+    eighth bit set, that Note On and Note Off events are always 3 bytes long,
+    etc.
+
+Where messages are communicated, the writer is responsible for writing valid
+messages, and the reader may assume that all events are valid.
+
+If a midi:MidiEvent is serialised to a string, the format should be
+xsd:hexBinary, for example:
+
+    :::turtle
+    [] eg:someEvent "901A01"^^midi:MidiEvent .
