Convert to build2-based build

Also add symbol exporting, missing const in a few places in the API, as well
as a basic test.

+# libgenx - XML serializer C library
+
+A portable, dependency-free, MIT-licensed XML push-serializer library for C.
+
+```
+#include <libgenx/genx.h>
+
+int main()
+{
+  genxWriter w = genxNew(NULL, NULL, stdout);
+  genxStartDocSender(w, &stdioSender);
+  genxStartElementLiteral(w, (utf8)"http://example.org/1", (utf8)"greeting");
+  genxAddAttributeLiteral(w, (utf8)"http://example.com/2", (utf8)"type", (utf8)"well-formed");
+  genxAddText(w, (utf8)"Hello world!");
+  genxEndElement(w);
+  genxEndDocument(w);
+  genxDispose(w);
+}
+```
+
+This is a cleaned up, fixed, and enhanced version of [Tim Bray's
+Genx](https://www.tbray.org/ongoing/genx/docs/Guide.html). Note that support
+for `genxStartDocFile()` (which depends on `<stdio.h>`) has been removed.
+See the `basics` test for an example of how to achieve the same yourself.
