[patch] 64 bit types in bitypes.h

[Tim Mooney]

[cc'ed to exports at crypto.com.  This patch contains no changes to cryptographic
routines, it only changes how the package's configure script works]

[I'm not subscribed to this list, please cc me on responses.  Thanks]

I noticed a minor configure problem in OpenSSH 2.9p2.  Basically, configure
will check sys/types.h for various "sized" prototypes, and then it separately
checks for int64_t and u_int64_t.  If it doesn't find the standard sized
types (int32, int16, etc) it falls back to checking sys/bitypes.h *but* it
doesn't check for the 64 bit types in there.  It should.

The patch below my sig addresses the problem.

Also, unless there's a good reason I'm not aware of, the newer inttypes.h
header file should also be checked, in the event that the typedefs aren't
available in either of the other header files (inttypes.h should probably
even be preferred to sys/bitypes.h).
