fncache: make debugrebuildfncache not fail on broken fncache...
fncache: make debugrebuildfncache not fail on broken fncache The code reading the fncache changed in 5.0, to complain if the file is not \n terminated. This makes apparent the fact that the fncache gets corrupted. Make it possible to recover, instead of having `hg debugrebuildfncache` failing by saying `(run hg debugrebuildfncache)`. The corruption itself is most likely due to hg not using fsync in general, and so various bad things can happen. Here, the reported problems happened when running out of disk space. So I suspect that because the fncache is much bigger than the average commit/pull, when running out of disk space, the bulk of the pull may succeed, but the new fncache may get half-written and still renamed into place.

# Rust builds with a modern MSVC and uses a newer CRT.
# Python 2.7 has a shared library dependency on an older CRT (msvcr90.dll).
# We statically link the modern CRT to avoid multiple msvcr*.dll libraries
# being loaded and Python possibly picking up symbols from the newer runtime
# (which would be loaded first).
