Make Requests_Transport_cURL::stream_headers accessible

[adri]

While fixing this issue in php-vcr I noticed that a curl header function references the protected function Requests_Transport_cURL::stream_headers.

This works as long as the caller of the callback is in the same "class scope" but not when calling it from somewhere else like php-vcr does. When running the integration tests I get the following error:

Invalid callback Requests_Transport_cURL::stream_headers, cannot access protected method Requests_Transport_cURL::stream_headers()

When I make the method public, it works. Would you like to do this or would you prefer another way to allow for calling this method?

(semi-related, sorry for hijacking: @rmccue, ditch 5.2 and use this neat PHP-VCR to solve the ongoing external HTTP request!!)

@ozh At the moment php-vcr can't intercept fsockopen or stream_socket_client, see the issue on php-vcr. Using php-vcr for Requests would work only for the cURL part. In theory "raw requests" can also be intercepted but I couldn't find the time yet to implement it.

Btw. PHP 5.3+ would only be necessary for running tests, not for the library itself.
