 Several types are supported for fetch-args. Uprobe tracer will access memory
 by given type. Prefix 's' and 'u' means those types are signed and unsigned

 String type is a special type, which fetches a "null-terminated" string from
 user space.
 Bitfield is another special type, which takes 3 parameters, bit-width, bit-
