Custom HTTP methods support

[Grzegorz Zdanowski]

I don't know if it's really possible (see https://github.com/libevent/libevent/issues/427), but support for custom HTTP methods, besides these defined in CMD_* constants would be more than great.

Currently in order to support them no HTTP support classes can be used, which means building parser from scratch.

Edit: While I'm not a C guy I did an research and played a while with libevent along with digging into pecl-event code - from what I see it shouldn't be so difficult to add support for custom methods. See a comment I left: https://github.com/libevent/libevent/pull/327#issuecomment-263107034

@kiler129 Yes, it will be easy when the patch will be applied. Let's wait for the Libevent team then?

As long as Libevent doesn't support custom methods, I can do nothing about it in the extension, I'm afraid.

Feel free to re-open the issue, when the Libevent team introduces the feature in upstream.
