Remove coupling between AP_RCProtocols SRXL2 and DSM

[peterbarker]

Having the DSM backend calling into the SRXL2 backend isn't nice, so this fixes that.

Two commits, one changing namespaces the other moving the code into the correct files.

Not sure the define inclusion is correct

[andyp1per]

I don't think you can do this can you because the define is inside the video tx header

[peterbarker]

I can get away with it because the header is transitively included via AP_RCProtocol.h

I've added an explicit include in this file.

.... that transitive include is a work of evil - the include at the end of AP_RCProtocol.h....

Change looks good to me, would just like to verify that nothing is broken as this is a code path that doesn't get a lot of use

I'm happy to buy some hardware to test with if you can point me at it.

I'd rather not have to wait for that hardware to arrive, however :-)

[andyp1per]

I can test - give me a few days

[peterbarker]

I can test - give me a few days

So I did that :-)

Any luck?

Urg, I have realized I can't test this as I sold my more modern Spektrum TX and the older DX8 I have does not support VTX updates. So better just go in.

[peterbarker]

Thanks @andyp1per . Can you describe what hardware could be used to test this sort of thing?

[andyp1per]

It needs a modern Spektrum TX. Since I basically maintain the Spektrum code I should probably put a proposal forward to the committee for one. I have DX8 - an up-to-date DX8 would be sufficient.
