Define CURL_MULTIEASY when building this, to use my new curl_easy_perform() 

that uses the multi interface to run the request. It is a great testbed for
the multi interface and I believe we shall do it this way for real in the
future when we have a successor to curl_multi_fdset().

/***************************************************************************

***************************************************************************
*
* The *new* curl_easy_perform() is the external interface that performs a
* transfer previously setup.
*
* Wrapper-function that: creates a multi handle, adds the easy handle to it,
* runs curl_multi_perform() until the transfer is done, then detaches the
* easy handle, destroys the multi handle and returns the easy handle's return
* code. This will make everything internally use and assume multi interface.
