[rfc][35/37] Eliminate builtin_type_ macros: Use target arch in bsd-uthread.c

[uweigand at de dot ibm dot com]

Hello,

bsd-uthread.c uses builtin_type_void_data_ptr to access target pointers.
As the thread layers (like shared library layers) should now be using
per-target architecture, this patch changes every such use to refer to
the builtin types defined by target_gdbarch instead.

Bye,
Ulrich

ChangeLog:

	* bsd-uthread.c (bsd_uthread_read_memory_address): New function.
	(bsd_uthread_fetch_registers, bsd_uthread_store_registers,
	bsd_uthread_wait, bsd_uthread_find_new_threads): Use it.
