SPCI: Introduce SPCI_MSG_SEND.
Morph the vmapi service HF_MAILBOX_SEND onto SPCI_MSG_SEND.
The current SPCI_MSG_SEND only allows for implementation defined
messages to be exchanged between VMs.
The new SPCI service returns SPCI_SUCCESS if message is delivered or one
of the following error codes:
SPCI_INVALID_PARAMETER: one of the parameters in the header does
not conform;
SPCI_BUSY: the mailbox was full or the target VM does not exist.
Adapted the tests to this new service.
Added tests specific to spci_message_init and spci_msg_send.
