133f202b19 gdbstub: Move GdbCmdParseEntry into a new header file 
Move GdbCmdParseEntry and its associated types into a separate header
file to allow the use of GdbCmdParseEntry and other gdbstub command
functions outside of gdbstub.c.

Since GdbCmdParseEntry and get_param are now public, kdoc
GdbCmdParseEntry and rename get_param to gdb_get_cmd_param.

This commit also makes gdb_put_packet public since is used in gdbstub
command handling.

0820a075af gdbstub: Adjust gdb_do_syscall to only use uint32_t and uint64_t 
Pass %x as uint32_t and %lx as uint64_t; pass the address
of %s as uint64_t and the length as uint32_t.

Add casts in semihosting/syscalls.c from target_ulong to
uint64_t; add casts from int to uint32_t for clarity.

131f387d74 gdbstub: split out softmmu/user specifics for syscall handling 
Most of the syscall code is config agnostic aside from the size of
target_ulong. In preparation for the next patch move the final bits
of specialisation into the appropriate user and softmmu helpers.

c566080cd3 gdbstub: move syscall handling to new file 
Our GDB syscall support is the last chunk of code that needs target
specific support so move it to a new file. We take the opportunity to
move the syscall state into its own singleton instance and add in a
few helpers for the main gdbstub to interact with the module.

I also moved the gdb_exit() declaration into syscalls.h as it feels
pretty related and most of the callers of it treat it as such.
