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.

+   @defgroup uri-map URI Map
+   @ingroup lv2
+
+   A feature for mapping URIs to integers.
+
+   This extension defines a simple mechanism for plugins to map URIs to
+   integers, usually for performance reasons (e.g. processing events typed by
+   URIs in real time). The expected use case is for plugins to map URIs to
+   integers for things they 'understand' at instantiation time, and store those
+   values for use in the audio thread without doing any string comparison.
+   This allows the extensibility of RDF with the performance of integers (or
+   centrally defined enumerations).
+
+   See <http://lv2plug.in/ns/ext/uri-map> for details.

+     value (e.g. limited range). This value may be NULL if the plugin needs
+     an ID for a URI in general. Extensions SHOULD NOT define a context

+     This function is referentially transparent; any number of calls with the

+     plugin instance (though the same URI may return different values with a
+     different map parameter). However, this function is not necessarily very
+     fast: plugins SHOULD cache any IDs they might need in performance
+     critical situations.
+
+     The return value 0 is reserved and indicates that an ID for that URI
+     could not be created for whatever reason. Extensions MAY define more
+     precisely what this means in a certain context, but in general plugins
+     SHOULD handle this situation as gracefully as possible. However, hosts
+     SHOULD NOT return 0 from this function in non-exceptional circumstances
+     (e.g. the URI map SHOULD be dynamic). Hosts that statically support only
+     a fixed set of URIs should not expect plugins to function correctly.
