ubusd: don't free messages in ubus_send_msg() anymore
This makes it clear that `ubus_msg_send()` is only
about sending and queue-ing messages, and has nothing
to do with free-ing.
It can be a bit misleading/confusing when trying to go
through the code and make assumptions about whether a
buffer is free'd in ubus_send_msg(), or is free'd outside.
In `ubusd_proto_receive_message()` the `ubus_msg_free()`
is now called before the `if (ret == -1)` check.
That way, all callbacks will have their messages free'd,
which is what's desired, but confusing, because:
* ubusd_handle_invoke() called ubus_msg_free() before returning -1
* ubusd_handle_notify() called ubus_msg_free() before returning -1
* ubusd_handle_response() called ubus_msg_send(,,free=true) before returning -1
* ubus_msg_send() would call ubus_msg_send(,,free=false)
* all other callback callers would `ubus_msg_send(,,free=true)`
(free the buffers in ubus_msg_send() )
In all other places, where `ubus_msg_send(,,free=true)`
an explicit `ubus_msg_free()` was added.

libubus: Fix deletion from context's object AVL tree when removing object
Objects are stored in the ubus context in an AVL tree. An AVL tree
node contains a pointer to a key value. For the ubus context, this
points to the id member of the object structure. In
ubus_remove_object_cb, the id member is set to zero and then after,
avl_delete is called and fails. To fix this, we call avl_delete
before setting the object id to zero.

libubus: expose ubus_connect_ctx() in public API
ubus_connect_ctx() is equivalent to ubus_connect() but accepts a
pointer to a previously allocated ubus_context struct.
ubus_shutdown() is made available as an alternative to ubus_free()
to clean up contexts initialised by ubus_connect_ctx().

ubus: add count test to validate large message sizes
Client creates a string "1 2 3 ... 10000 ...", sends it to the server
along with the maximum number in the string.
Server creates another string like the client sent.
It validates it and, returns strcmp()'s result.
This is loop-ed every 2 seconds.

ubusd: replace ubusd_msg_unshare() with ubus_msg_new() to prevent invalid free-ing
The realloc is problematic mostly with large packets, as the pointer changes
so what eventually gets free'd is invalid.
Note that ub ptr param in the call will be passed on to a ubus_msg_free(),
right after ubus_msg_ref() finishes.
This bug stayed hidden the same way as the bug in libubus writev_retry().
Since the write/sendmsg function can send about ~200k the ubus_msg_enqueue()
call does not get triggered.
