Porting the P&E Multilink Universal adapter

[<cw...@th...>]

All,

I'm currently trying to port P&E Multilink Universal[1,2]. This is
currently supported by pyocd-pemicro[3] using external dll[4].

I have successfully create a c interface for for the dll and I'm now
trying to integrate this into the openocd code.

I have add it as a hla interface as the dll only supports writing to
memory and I'm having problems getting the system to compile the new
adapter as no hla interfaces have been compiled into the program.

I've attached a patch from the current head(918811) and my code so I
was wondering if anyone could give me any pointers on what I might be
doing wrong.

Many thanks,
Chris
