debug: move debug features from misc to subsys/debug Change-Id: I446be0202325cf3cead7ce3024ca2047e3f7660d Signed-off-by: Anas Nashif <anas.nashif@intel.com>

debug: add target GDB server The GDB server implements a set of GDB commands, such as read/write memory, read/write registers, connect/detach, breakpoints, single-step, continue. It is not OS-aware, and thus provides a 'system-level' debugging environment, where the system stops when debugging (such as handling a breakpoint or single-stepping). It currently only works over a serial line, taking over the uart_console. If target code prints over the console, the GDB server intecepts them and does not send the characters directly over the serial line, but rather wraps them in a packet handled by the GDB client.

debug: add safe memory access routines Introduces the following routines to provide safe access to memory: _mem_probe() _mem_safe_read() _mem_safe_write() _mem_safe_write_to_text_section() Those routines will return an error if the memory is not accessible rather than potentially crash. This implementation is based on the image's boundaries; thus it allows read/write access to the data/bss/init sections and read access only to the text/rodata sections. All other memory is considered invalid, even if addressable. This includes the leftover from the RAM at the end of the image, since there is no support for using it (e.g. there is no dynamic allocator).

kernel: Add OpenOCD support In order for OpenOCD to have a high-level view of an RTOS, it uses the GDB protocol to obtain symbols from the system. The GDB protocol, however, does not allow obtaining fields from structures directly, and hardcoding offsets is not only brittle (due to possibly different architectures or changes in the code), it's also infeasible considering Zephyr is highly-configurable and parts of key structs can be compiled in or out. Export an array with offsets for these key structs. Also add a version element in that array to allow changes in those structs.
