TODO: added two more libcurl ideas

Moved some ideas from "next major" to just ordinary ideas since we can
always add new things while keeping the old without doing a "next
major".

+1.12 have form functions use CURL handle argument
+
+ curl_formadd() and curl_formget() both currently have no CURL handle
+ argument, but both can use a callback that is set in the easy handle, and
+ thus curl_formget() with callback cannot function without first having
+ curl_easy_perform() (or similar) called - which is hard to grasp and a design
+ mistake.
+
+ The curl_formadd() design can probably also be reconsidered to make it easier
+ to use and less error-prone. Probably easiest by splitting it into several
+ function calls.
+
+1.13 Add CURLOPT_MAIL_CLIENT option
+
+ Rather than use the URL to specify the mail client string to present in the
+ HELO and EHLO commands, libcurl should support a new CURLOPT specifically for
+ specifying this data as the URL is non-standard and to be honest a bit of a
+ hack ;-)

+1.14 Typesafe curl_easy_setopt()
+
+ One of the most common problems in libcurl using applications is the lack of
+ type checks for curl_easy_setopt() which happens because it accepts varargs
+ and thus can take any type.
+
+ One possible solution to this is to introduce a few different versions of the
+ setopt version for the different kinds of data you can set.
+
+  curl_easy_set_num() - sets a long value
+
+  curl_easy_set_large() - sets a curl_off_t value
+
+  curl_easy_set_ptr() - sets a pointer
+
+  curl_easy_set_cb() - sets a callback PLUS its callback data

+2.3 Non-blocking curl_multi_remove_handle()
+
+ The multi interface has a few API calls that assume a blocking behavior, like
+ add_handle() and remove_handle() which limits what we can do internally. The
+ multi API need to be moved even more into a single function that "drives"
+ everything in a non-blocking manner and signals when something is done. A
+ remove or add would then only ask for the action to get started and then
+ multi_perform() etc still be called until the add/remove is completed.
