arm process record and reversible implementation

[paawan oza]

Hi,

I think of two phase implementation as below.

phase 1: 
> function 'arm_process_record' will be added in arm-tdep.c
> it is supposed to take care of registers, memory, function calls etc... without 
>touching linux ABI.
> I hope above thing take care comeplte non-ABI part.

phase 2:
> linux ABI part will be taken care and same to be added in arm-linux-tdep.c 
>(such as signals, syscall etc...)
(still I am not sure of arm-linux-kernel and relevant virtual machine support at 
this time it it is getting difficult to setup, but anyways thats at later 
stage).

Oza.
