Improve UUID1 MAC address calculation and related tests.
There are two bits in the MAC address that are relevant to UUID1. The first is the locally administered vs. universally administered bit (second least significant of the first octet). Physical network interfaces such as ethernet ports and wireless adapters will always be universally administered, but some interfaces --such as the interface that MacBook Pros communicate with their Touch Bars-- are locally administered. The former are guaranteed to be globally unique, while the latter are demonstrably *not* globally unique and are in fact the same on every MBP with a Touch Bar. With this bit is set, the MAC is locally administered; with it unset it is universally administered.
The other bit is the multicast bit (least significant bit of the first octet). When no other MAC address can be found, RFC 4122 mandates that a random 48-bit number be generated. This randomly generated number *must* have the multicast bit set.
The improvements in uuid.py include:
* Preferentially return a universally administered MAC address, falling back to a locally administered address if none of the former can be found.
* Improve several coding style issues, such as adding explicit returns of None, using a more readable bitmask pattern, and assuming that the ultimate fallback, random MAC generation will not fail (and propagating any exception there instead of swallowing them).
Improvements in test_uuid.py include:
* Always testing the calculated MAC for universal administration, unless explicitly disabled (i.e. for the random case), or implicitly disabled due to running in the Travis environment. Travis test machines have *no* universally administered MAC address at the time of this writing.
Optimized bytes and bytes_le properties of UUID and UUID constructor with
bytes_le argument.
Fixed a bug in handling an error occured during reading from a pipe in
_ipconfig_getnode().
I didn't realize LC_ALL was an override, and I should have. I tried to
make a test, but it is not clear that the LC variables actually affect
the strings that uuid is using to parse the command output.

The C function used by uuid.uuid4 is broken on
OSX 10.6 in that after os.fork() the parent and
child generate the same sequence of UUIDs.
This patch falls back to the the Python implementation
on OSX 10.6 or later.
Fixes issue #8621.

No detailed change log; just check out the change log for the py3k-pep3137
branch. The most obvious changes:
- str8 renamed to bytes (PyString at the C level);
- bytes renamed to buffer (PyBytes at the C level);
- PyString and PyUnicode are no longer compatible.
I.e. we now have an immutable bytes type and a mutable bytes type.
The behavior of PyString was modified quite a bit, to make it more
bytes-like. Some changes are still on the to-do list.
Change the UUID properties to use @property.
Change the UUID API so that .bytes and .bytes_le return, and the
corresponding arguments to __init__() require, values of type 'bytes'.

Fixed: The prefix field is no longer used in PAX_FORMAT (in
conformance with POSIX).
Fixed: In read mode use a possible pax header size field.
Fixed: Strip trailing slashes from pax header name values.
Fixed: Give values in user-specified pax_headers precedence when
writing.
Added unicode tests. Added pax/regtype4 member to testtar.tar all
possible number fields in a pax header.
Added two chapters to the documentation about the different formats

This ought to be backported to 2.5.2 or at least 2.6.
