[ros-dev] headers: LPC names

[Emanuele Aliberti]

Hi all,
this is just a little note for those nice guys that are working hard in 
cleaning the headers.

LPC proper and related names are divided in three groups:
- PORT_xxx or xxx_PORT (API/struct/macro for LPC port object handling; 
end user API);
- LPC_xxx (API/struct/macro used in other executive subsystems or drivers);
- LPCP_xxx (executive mode only private LPC facility memory object names).

(I do not guarantee it is 100% correct; some subsets may overlap).
