reallocating a new skb head, check if the current one has the needed

Do this check only if skb head is not shared.

The mcfw *never* sends CMDDONE when rebooting. Changing this so that it always
sends CMDDONE *before* REBOOT is easy on Siena, but it's not obvious that we
could guarantee to be able to implement this on future hardware.

Given this, I'm less convinced that the protocol should be changed.

To reiterate the failure mode: The driver sees this:

 issue command
 receive REBOOT event

Was that reboot event sent before the command was issued, or in
response to the command? If the former then there will be a subsequent
CMDDONE event, if the latter, then there will be no CMDDONE event.

Options to resolve this are:

 1. REBOOT always completes an outstanding mcdi request, and we set
    the credits count to ignore a subsequent CMDDONE event with
    mismatching seqno.

 2. REBOOT never completes an outstanding mcdi request. If there is
    no CMDDONE event then we rely on the mcdi timeout code to complete
    the outstanding request, incurring a 10s delay.

I'd argue that (2) is tidier, but that incurring a 10s delay is a little
needless. Let's go with (1).

Moves the content of each native API message forwarding routine
into the sole routine that calls it, since the forwarding routines
no longer be called in isolation. Also removes code in each routine
that altered the outgoing message's importance level since this is
now no longer possible.

The previous function mapping (parent function, and child API) was
as follows:

   tipc_send2name
       \--tipc_forward2name

   tipc_send2port
       \--tipc_forward2port

   tipc_send_buf2port
       \--tipc_forward_buf2port

After this commit, the children don't exist and their functionality
is completely in the respective parent.

As part of the removal of TIPC's native API support it is no longer
necessary for TIPC to export symbols for routines that can be called
by kernel-based applications, nor for it to have header files that
kernel-based applications can include to access the declarations for
those routines. This commit eliminates the exporting of symbols by
TIPC and migrates the contents of each obsolete native API include
file into its corresponding non-native API equivalent.

The code which was migrated in this commit was migrated intact, in
that there are no technical changes combined with the relocation.
