And here is v3 with support for pg_rewind tests. One thing that I
noticed with this stuff is that the log redirection fails on Windows
with "cannot access file because it is used by another process",
because of system_or_bail that is used by a set of pg_ctl commands in
RewindTest.pm to stop, start and promote the test servers. I am
attaching a second patch switching those calls from system_or_bail to
IPC's run(), making the log capture method completely consistent
across platforms. In the first patch log redirection is done to NUL to
make the test work even if log output is lost, the split is done for
clarity and those patches should be applied together.

Note as well that this patch uses the following patches fixing
independent issues:
- Replace use of rm in initdb tests by rmtree:

- Add --debug for pg_rewind remote mode:

- Improve sleep processing of pg_rewind, windows being sometimes
susceptible about that as well...
