commit 5447f965f1e109f7ac9aeb91c0e3906969a4adb8
Author: Flavio Cruz <flaviocruz@gmail.com>

    Use c_string to define host_get_kernel_version and 
host_get_kernel_boot_info.
    
    The existing definitions for kernel_version_t and kernel_boot_info_t use
    (MACH_MSG_TYPE_STRING, length*8) which result in message types that have
    a single element of 512 or 4096 bytes (set as msgt_size). This results
    in MiG generating mach_msg_type_long_t. Using c_string has the benefit
    of moving this size to be defined as msgt_number which doesn't overflow.
    This will allow us to simplify the 64 bit RPC ABI since all msgt_size can
    be defined with just 8 bits (as it should be expected).
    
    The resulting implementation is the same but we still need to define new
    RPCs since server and user expect different mach_msg_type_t.
