Layout of coprocessor registers in the elf_xtregs_t and xtregs_coprocessor_t may be different due to alignment. Thus it is not always possible to copy data between the xtregs_coprocessor_t structure and the elf_xtregs_t and get correct values for all registers. Use a table of offsets and sizes of individual coprocessor register groups to do coprocessor context copying in the ptrace_getxregs and ptrace_setxregs. This fixes incorrect coprocessor register values reading from the user process by the native gdb on an xtensa core with multiple coprocessors and registers with high alignment requirements.
