Manually bootstrap JRuby after all.
...
After discussing this with @headius I've decided to do this the manual way
anyway. Apparently the basic load service stuff is deprecated and not very
reliable.

Break up the Ragel C grammar.

The grammar is now broken up in to a base lexer and a C lexer. This allows the
same grammar to also be used in the Java code.

JRuby lexer boilerplate with actual input.

This doesn't actually lex anything just yet but at least the input from Ruby is
in place.

Since I'm not using any Ragel version specific features it's not really needed
to check for the version.

Use rb_enc_str_new instead of rb_enc_str_new_cstr.

The latter in combination with strndup() would leak large amounts of memory.

Initial setup using a C extension.
...
While I've tried to keep Oga pure Ruby for as long as possible the performance
of Ragel's Ruby output was not worth the trouble. For example, lexing 10MB of
XML would take 5 to 6 seconds at least. Nokogiri on the other hand can parse
that same XML into a DOM document in about 300 miliseconds. Such a big
performance difference is not acceptable.
To work around this the XML/HTML lexer will be implemented in C for
MRI/Rubinius and Java for JRuby. For now there's only a C extension as I
haven't read up yet on the JRuby API. The end goal is to provide some sort of
Ragel "template" that can be used to generate the corresponding C/Java
extension code. This would remove the need of duplicating the grammar and
associated code.
The native extension setup is a hybrid between native and Ruby. The raw Ragel
stuff happens in C/Java while the actual logic of actions happens in Ruby. This
adds a small amount of overhead but makes it much easier to maintain the lexer.
Even with this extra overhead the performance is much better than pure Ruby.
The 10MB of XML mentioned above is lexed in about 600 miliseconds. In other
words, it's 10 times faster.

Patch the Ragel lexer after generating it.
...
This further increases throughput of the lexer. On MRI this seems to save
around one second or so. It now sits at ~6,8 seconds in the big XML benchmark.
On JRuby, combined with some JIT options and invoke dynamic enabled, this can
reduce the average lexing time to around 3,5 seconds. Rubinius, also with a
few aggressive JIT options, seems to stick around 9 seocnds.

Removed XML::Lexer#buffering?
...
Instead of wrapping a predicate method around the ivar we'll just access it
directly. This reduces average lexing times in the big XML benchmark from 7,5
to ~7 seconds.

profiling data and makes the actual profiling easier.
