Changing the ubus message header fields from 'host' order to 'network' order
allows passing ubus messages between hosts with different endianity.
Example use (creating a ubus proxy):
on host A (e.g. big endian router already running ubusd), run:
$ socat TCP-LISTEN:5699,fork UNIX:/var/run/ubus.sock &
On host B (e.g. little endian development PC) run:
$ socat UNIX-LISTEN:/var/run/ubus.sock,fork TCP:<host A IP>:5699 &
Now ubus applications can be run on host B and seamlessly interact with ubus
applications on host A.

Add ubus_auto_shutdown function, which ensures any pending uloop_timer is cancelled before calling ubus_shutdown on the context.
This avoids a condition where ubus_shutdown() is called during ubus_auto_connect attempting a reconnection.

At the moment, we do our own null checks before calling ubus_free().
The likely-hood of 'ctx' being null (in ubus_free()) is low,
but since free() handles null, might make sense for ubus_free() to do so as well.

As the man page explains:
"Specifying a timeout of zero causes poll() to return immediately,
even if no file descriptors are ready."
The use of 0 as timeout could cause libubus to busy loop if the
socket was non-blocking. For blocking sockets, this was less
apparent as the subsequent read() would then block.

Append ubus notification messages to the tail of the pending list
so they're processed in the order as they're put onto the pending list

The value from getglobal wasn't being removed from the stack,
resulting in an ever growing stack in the ubus event handler.

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().

__init has a naming collision with C++ and prevents ubus_common.h
from being included. Instead, use __constructor as defined from
libubox.

Context: 1 loop with a single ubus_invoke() that times out calls
uloop_end() which ends the loop, and thus ends the application.

Set ctx->msgbuf.data to NULL during the call. If ctx->msgbuf is needed
during the call, a new buffer will be allocated. If not,
ctx->msgbuf.data is restored to the previous value afterwards
