easy: resize receive buffer on easy handle reset
- In curl_easy_reset attempt to resize the receive buffer to its default size. If realloc fails then continue using the previous size. Prior to this change curl_easy_reset did not properly handle resetting the receive buffer (data->state.buffer). It reset the variable holding its size (data->set.buffer_size) to the default size (READBUFFER_SIZE) but then did not actually resize the buffer. If a user resized the buffer by using CURLOPT_BUFFERSIZE to set the size smaller than the default, later called curl_easy_reset and attempted to reuse the handle then a heap overflow would very likely occur during that handle's next transfer.
