Bug in show objective c messages with Leopard??? Used the same code from nop to null routine. Added a new command 'stepo'.
This command will step a temporary breakpoint on next instruction after the call, so you can skip over. Support for the jump decision will display if a conditional jump will be taken or not.
Moved gdb options to the beginning makes more sense. Added support to dump message being sent to msgSend easier to understand what's going on.

Create the 16 and 8 bit cpu registers gdb doesn't have them by default. And 32bits if we are dealing with 64bits binaries. Print shared libraries linked to target. Print what debugger does when program gets various signals.
Disassemble a specified section of memory. Default is to disassemble the function surrounding the PC program counter. With one argument, ADDR1, the function surrounding this. Print eight hexadecimal bytes starting at address ADDR. Display 16 lines of a hex dump of address starting at ADDR.
