vanjeff 93c0bdec28 This revision can only work with Intel(c) UDK Debugger Tool version 1.2 or greater. Detailed change log is as below: 
1. Define the transfer protocol revision mechanism. Increase the revision number to 0.2 and inform user to use the latest one when the HOST software is too old.
   New HOST software will implement logic to handle all other revision mismatch cases.
2. Define new debug message packet to print the debug agent trace information by debug port channel.
3. Add check sum mechanism in the communication protocol between TARGET/HOST.
4. Introduced one "try" mechanism to avoid Debug Agent crashed by some invalid HOST command.
5. Enable the late-attach feature: Change the break in from "!" to "\xFC". Add a new short symbol "\xFA" for attach and a new debug command for detach.
6. Support Terminal work on debug port by install EFI Serial IO protocol upon Debug Communication Library.
7. Enable CPUID feature.
8. Enable the hardware data breakpoint.
9. add handshake to improve usb debug cable identify stability issue.
10.Refine all the communication protocol packet to improve extensibility and debugging performance.
  a. Use 64bit for IO port address.
  b. Add additional Width field to READ_MEMORY/WRITE_MEMORY.
  c. Add SEARCH_SIGNATURE support to speed the symbol finding for late attach.
  d. Remove READ_GROUP register.
  e. Add READ_ALL_REGISTERS support (WinDbg always requests to read all registers).
11.Move AcquireDebugPortControl () in advance to fix resource collision on IpiSentByApFlag.
12.Fix IO break point does not work issue in PEI phase.
13.Avoid BSP/APs collision when they met break point at the same time.
14.Solve a bug of calculating debug handle in sec phase.
15.Use mailbox content at Dxe phase but not clear it and reinitialize again.
16.Fix FP/MMX/XMM/IO/MSR access issue in both Gdb and WinDbg.
