linux-user: Define ELF_ET_DYN_BASE in $guest/target_mman.h Copy each guest kernel's default value, then bound it against reserved_va or the host address space.

linux-user: Provide MADV_* definitions Provide MADV_* definitions using target_mman.h header, similar to what kernel does. Most architectures use the same values, with the exception of alpha and hppa.
