[PATCH] Turn mach_msg_type_{name,size}_t into unsigned chars.

[Flavio Cruz]

mach_msg_type_name_t and mach_msg_type_size_t are used as 8 bit fields in
mach_msg_type_t struct, therefore they should be treated as unsigned char's to
avoid warnings when using macros such as MACH_MSG_TYPE_POLYMORPIC.

* include/mach/message.h: Update typedef.
* include/mach/std_types.defs: Change to char.
