[GSOC] api- GSoC report 3

Hi, I've been able to complete the extension versioning section during the past week. What I've been doing: * Included a function to get the latest version of an extension available * Functions to convert version from major.minor[.build[.revision]] format to an uint and vice versa are provided. - when representing the version in uint first 8 bits will be used for major and the next 8 for minor and so on * A few memory leaks were fixed The zend_ext_api_get_latest_version gives the version in the uint form, since it will be easier to be handled by the extensions which need it. Also it can be converted to the major.minor[.build[.revision]] form if required. What's next: I will prepare a document describing the interface of ext_api, so that you can test it out if possible and give some feedback. So far I've tested most of the cases I could think of whenever I added new funcitonality to the code. I will do some more testing in the next few weeks and upload the test code if possible. Note: I have exams at my university from tomorrow onwards till 21st June, so I won't be able to give a lot of time for the project during that period :P . Thanks Varuna
