lfutil: provide a hint if the largefiles/lfs cache path cannot be determined
A coworker hit this error using an LFS repo in a stripped down environment, and
didn't know how to resolve it.
The final conditional is a bit fast and loose, but there is currently no 'posix'
test in hghave, and it doesn't seem like it's worth adding for this since I
think Windows is the only non-POSIX platform we run tests on.

setup: exclude the __index__ module from itself when generating
This module is generated on Windows to hold all of the extension names and the
help summaries, so that they are discoverable inside the py2exe zipfile. The
problem is this file is generated by dumping the disabled list, and that list
comes from walking the filesystem. So once an install from source into a
virtualenv created this module, then next build from source from that virtualenv
would also see __index__.py in the filesystem, and include it. Clearly that's
wrong because this isn't a real extension, so just filter it from the list when
generating it.
The Mercurial installer was unaffected by this, but the TortoiseHg package was.
In the final package, `hg help -v extensions` and the panel of extensions both
showed it.

tests: stabilize test-amend.t on Windows
If $TESTTMP isn't quoted in this context, it ends up like
`C:Temphgtests.pikkoxchild1test-amend.t-obsstore-off`.

tests: replace truncate(1) with inline python
MSYS doesn't have truncate(1) installed by default, and FreeBSD looked unhappy
with the arguments provided.
