Added stub RTC lib, turned on option of building debug agent (GDB STUB) into SEC. Added the platform library template needed to break into GDB stub with ctrl-c. Cleaned up PCDs for selecting serial ports for Console or GDB usage. Filled in GDB Serial Port lib.

Template for ArmEb DebugAgentLib.
|

|

For ARM we reserve FIQ for the Debug Agent Timer. We don't care about
|
||||
laytency as we only really need the timer to run a few times a second
|
||||
(how fast can some one type a ctrl-c?), but it works much better if
|
||||
the interrupt we are using to break into the debugger is not being
|
||||
used, and masked, by the system.
