kamil 241cf91ddc Add support for hardware assisted watchpoints/breakpoints API in ptrace(2) 
Add new ptrace(2) calls:
 - PT_COUNT_WATCHPOINTS - count the number of available hardware watchpoints
 - PT_READ_WATCHPOINT   - read struct ptrace_watchpoint from the kernel state
 - PT_WRITE_WATCHPOINT  - write new struct ptrace_watchpoint state, this
                          includes enabling and disabling watchpoints

The ptrace_watchpoint structure contains MI and MD parts:

typedef struct ptrace_watchpoint {
	int		pw_index;	/* HW Watchpoint ID (count from 0) */
	lwpid_t		pw_lwpid;	/* LWP described */
	struct mdpw	pw_md;		/* MD fields */
} ptrace_watchpoint_t;

For example amd64 defines MD as follows:
struct mdpw {
	void	*md_address;
	int	 md_condition;
	int	 md_length;
};

These calls are protected with the __HAVE_PTRACE_WATCHPOINTS guard.

Tested on amd64, initial support added for i386 and XEN.
