protoc-gen-php: Support for package namespaces

[cypres]

Been working on rudimentary support for package based namespaces.

It needs some additional work before it should/could be merged, but I thought I would post it anyway. Especially the following would be nice:

• PSR-0 compliance
• Support for nested types with namespaces instead of underscores (almost requires PSR-0)
• A way to disable the feature via (php) option or otherwise

It works though, so if you really need/want namespaces it's usable.

Hi, this is nice PR!

• A way to disable the feature via (php) option or otherwise

do you have some time to implement this feature?

[cypres]

Sure I can add way to toggle it on and off. I need to work out how to keep both features with minimal code impact, but I'll work on it next week. Preferably while also keeping support for (php).namespace option.

I should also add some new tests if you want to merge it.

[cypres]

Sorry for the delay. I'm pretty tied up currently. I've re-worked the feature to apply more cleanly, and for it to be optional. Unit testing still missing atm.

@duedal Thank you. It looks good to me. I want testcases. But It does not required atm as protoc-gen-php don't have it.

could you send another unit test PR when you have time?

[cypres]

Thank you, will send a PR with tests later, if all goes well I should be able to find the time next week.

@duedal btw, what testing framework do you use for this? I'd like to add gtest for conformance test. Please tell me current status
