Yao Qi 4ac248ca0b Add target_xfer_partial_ftype
This patch adds a typedef target_xfer_partial_ftype.  When we change
the signature of xfer_partial functions (for example, adding a new
parameter), we don't have to modify all of their declarations.

This patch also updates the type of parameters of target_xfer_partial
from "void *" to "gdb_byte *".
