Issue #12644: document the '%a' conversion in the old string formatting operations. Patch prepared together with Ezio Melotti

As a side effect, this now allows the rjust, ljust and center methods of
bytes and bytearray to accept a bytearray argument.

- Use shortcut dist.version instead of going through metadata;
- Use %r throughout to display project names and paths.

This will help scripts calling pysetup know if a command failed.
Printing/logging was also made more consistent, and a few things were
cleaned up.  In particular, the error/Ctrl-C handling was moved from the
_run function up to the main function.

The run action is not fixed yet; it returns the dist.Distribution
instance, which is needed by test_uninstall and not trivial to fix.

“pysetup list” or “pysetup list --all” will continue to return 0 if no
distribution is found (it’s not an error), but “pysetup list
some.project” will now exit with 1 if no matching installed distribution
is found.  Based on a patch by Kelsey Hightower.

The tests don’t use an internal distutils function anymore, and use
regular assertEqual with sorted lists instead of a convoluted manual
diff.

Also remove an extra docstring.

Adding Sandro Tosi to Doc/ACKS for this patch and all his work on the
docs mailing list and on the bug tracker.

R. David Murray and I think that it’s more useful to have these files
show up in the output of “hg status”, to let the user know that some
merged file have to be checked before commit.  If you want to ignore
these files in your clones, it’s possible to do so from another ignore
file; see the bug report for directions.

I’m leaving the .gitignore file alone, as I don’t know how git users
work with merges and conflicts.

The public names (Thread, Condition, etc.) used to be factory functions
returning instances of hidden classes (_Thread, _Condition, etc.),
because (if Guido recalls correctly) this code pre-dates the ability to
subclass extension types.

It is now possible to inherit from Thread and other classes, without
having to import the private underscored names like multiprocessing did.

A doc update will follow: a patch is under discussion on the issue.

This function used to live as pipes.quote, where it was undocumented but
used anyway.  (An alias still exists for backward compatibility.)  The
tests have been moved as is, but the code of the function was changed to
use a regex instead of a loop with string comparisons (at Ian Bicking’s
suggestion).  I’m terrible at regexes, so any feedback is welcome.
