gdbsupport: add type definitions for pid, lwp and tid
A following patch will want to declare variables of the same type as
some ptid_t components. To make that easy (and avoid harcoding those
types everywhere), define some type definitions in the ptid_t struct for
each of them. Use them throughout ptid.h.
I initially used pid_t, lwp_t and tid_t, but there is the risk of some
system defining the pid_t type using a macro instead of a typedef, which
would break things. So, use the _type suffix instead.
