How do they do it?

Carefully.  With a combination of very fast VFO/PLL switching, PIN diodes AND 
reed relays.

>Do they use a relay for T/R switching? 

It is a SPST power reed relay in most rigs, used only to disconnect 
the final so it doesn't sit across the RX.

>Do they use the same system in all their rigs?

Yes, but with some variations depending on IF, PLL use, etc.
