MFC r204051 (by imp):

n64 has a different size for KINFO_PROC_SIZE.

Approved by:	imp

MFC r207152:
Move the constants specifying the size of struct kinfo_proc into
machine-specific header files. Add KINFO_PROC32_SIZE for struct
kinfo_proc32 for architectures providing COMPAT_FREEBSD32. Add
CTASSERT for the size of struct kinfo_proc32.

MFC r207269:
Style: use #define<TAB> instead of #define<SPACE>.
