ad8ea5a8b2 Import the uuid_enc_le(), uuid_dec_le(), uuid_enc_be() and
uuid_dec_be() functions. These routines are not part of the
DCE RPC API. They are provided for convenience.

77fbf8f246 Avoid using intermediate variables by just comparing between
two values, the latter does not tend to have sign extension
and/or overflow bugs, and makes the code more obvious.

While I'm there, make use of a macro which is derived from
bin/ps/ps.c: ps_compat() to improve the readability of the
code.

da4ab3aa26 In DCE 1.1, the time_low value is defined as an unsigned 32-bit
integer.  Presently, our implementation employs an approach that
converts the value to int64_t, then back to int, unfortunately,
this approach can be problematic when the the difference between
the two time_low is larger than 0x7fffffff, as the value is then
truncated to int.

To quote the test case from the original PR, the following is
true with the current implementation:

865e1a56-b9d9-11d9-ba27-0003476f2e88 < 062ac45c-b9d9-11d9-ba27-0003476f2e88

However, according to the DCE specification, the expected result
should be:

865e1a56-b9d9-11d9-ba27-0003476f2e88 > 062ac45c-b9d9-11d9-ba27-0003476f2e88

This commit adds a new intermediate variable which uses int64_t
to store the result of subtraction between the two time_low values,
which would not introduce different semantic of the MSB found in
time_low value.

3031a4311e Fix two (2) bugs in one (1) statement:
o  fix the len argument of memcmp(3) to be the size of the node field
   of the uuid structure, not the size of the uuid structure itself.
   We're comparing the node fields...
o  uuid_compare(3) is specified to return -1, 0 or 1, depending on
   the outcome of the comparison. memcmp(3) returns the difference
   between the first differing bytes. Hence, we cannot ever return
   the return value of memcmp(3) as-is.

c544e42bcf libc header files are normally in src/include. Therefore, uuid.h has
been repo-copied from src/lib/libc/uuid to src/include. Update the
makefiles.

While in src/include/Makefile, reformat and resort INCS. Reverting
the functional change only involves removing uuid.h.

65393a863e Implement DCE 1.1 compliant UUID functions. Immediate use of these
functions is expected for uuidgen(1), mca(8) and gpt(8). Given the
generic use of UUIDs beyond the scope of the DCE 1.1 specification,
visibility of the data structure at all levels of the machine,
including firmware and the wish to not create a permanent build-
time FreeBSD-ism for DCE compliant applications by creating a new
library, it was decided that libc would be the least inappropriate
place. Also, because the UUID functions live in libc under IRIX as
well, we have maximized our portability and left as many options
open as possible.

This implementation introduces an extension not found in the
specification: the status parameter is allowed to be a NULL-
pointer. The reason for introducing the extension is because
the status is almost never of any use.

The manpage that's part of this commit is a minimal place-holder
and is further fleshed-out in the near future.
