The user protocols struct has not been const until now.
This has been painful for a while because the semantics of the protocols
struct look like it's going to be treated as const.
At context creation, the protocols struct has been getting marked with the context,
and three apis exploited that to only need to be passed a pointer to a protocol to
get access to the context.
This patch removes the two writeable members in the context (these were never directly
used by user code), changes all pointers to protocols to be const, and adds an explicit
first argument to the three affected apis so they can have access to context.
The three affected apis are these
LWS_VISIBLE LWS_EXTERN int
-lws_callback_on_writable_all_protocol(const struct lws_protocols *protocol);
+lws_callback_on_writable_all_protocol(const struct lws_context *context,
+ const struct lws_protocols *protocol);
LWS_VISIBLE LWS_EXTERN int
-lws_callback_all_protocol(const struct lws_protocols *protocol, int reason);
+lws_callback_all_protocol(struct lws_context *context,
+ const struct lws_protocols *protocol, int reason);
LWS_VISIBLE LWS_EXTERN void
-lws_rx_flow_allow_all_protocol(const struct lws_protocols *protocol);
+lws_rx_flow_allow_all_protocol(const struct lws_context *context,
+ const struct lws_protocols *protocol);
unfortunately the original apis can no longer be emulated and users of them must update.

This nukes all the oldstyle prefixes except in the compatibility code.
struct libwebsockets becomes struct lws too.
The api docs are updated accordingly as are the READMEs that mention
those apis.
