largefiles: use 'dirstate.dirs()' for 'directory pattern' relation check
original implementation queries whether specified pattern is related
or not to largefiles in target context by 'dirstate.__contains__()'.
but this can't recognize 'directory pattern' correctly, so this patch
uses 'dirstate.dirs()' for it.
this patch uses dirstate instead of lfdirstate in 'working' route
(second patch hunk for 'hgext/largefiles/reposetup.py'), because
'dirs()' information may be already built for dirstate but not yet for
lfdirstate at this point. this prevents lfdirstate from building up
and having 'dirs()' information.
revlog.parseindex must be able to parse the index file even if
an index entry is split between two 64k blocks. The ideal test
would be to create an index file with inline data where
64k < size < 64k + 64 (64k is the size of the read buffer, 64 is
the size of an index entry) and with an index entry starting right
before the 64k block boundary, and try to read it.
We approximate that by reducing the read buffer to 1 byte.
