procutil: use mercurial.windows.winstdout only on Python 2 and TTYs
Python 3 already works around the bug. The workaround is only needed when
writing to consoles. If stdout is a console, sys.stdout.isatty() is true.

procutil: split if condition
This prepares the code for subsequent changes where we need to differentiate
between the two cases.

procutil: explain better why line buffering is not possible
The sentence “On Python 3, buffered binary streams can't be set line-buffered.”
was imprecise, as all streams are just Python classes and we can implement our
own (which we did).

procutil: back out 8403cc54bc83 (make ....procutil.stderr unbuffered)
Changeset 8403cc54bc83 introduced code that opens a second file object
referring to the stderr file descriptor. This broke tests on Windows. The
reason is that on Windows, sys.stderr is buffered and procutil.stderr closed
the file descriptor when it got garbage collected before sys.stderr had the
chance to flush buffered data.
`procutil.stdout` had the same problem for a long time, but we didn’t realize,
as in CI test runs, stdout is not a TTY and in this case no second file object
is opened.

test-clone-uncompressed: use config to silence the lock warning
The ui.timeout.warn option can solve the issue6237 in a cleaner way than what
was done in 752da6863e39. That way, possible other unexpected error output will
not be silenced.

hooklib: fix detection of successors for changeset_obsoleted
Provide a hook for obsutil.getobsolete to be used with either a
transaction or the changes item of the transaction, since hooks only
have access to the latter. Use that to find the correct list of
revisions with obsmarkers, even new ones, and then filter out revisions
with known successors.
Move the processing from pretxnclose to txnclose as the transaction
access itself is no longer necessary. This is more in line with notify
and ensures that sanity checks can abort the transaction first.

fix: prefetch file contents
This prevents the worker subprocesses from contacting the server individually,
which is either inefficient, or leads to problems if the connection is shared
among them.

fix: obtain base paths before starting workers
This moves calculation of base paths to before work is dispatched.
While this does mean that copy tracing will be serialized instead of
parallel, it is necessary to be able to prefetch the base contents
in a batch, which will likely be more efficient.

scmutil: allowing different files to be prefetched per revision
The old API takes a list of revision separate from the file matcher, and thus
provides no way to fetch different sets of files from each revision. In
preparation for adding one such usage, I'm changing the API to take a list of
(revision, file matcher) tuples instead.
