largefiles: avoid dynamically subclassing context instances
E.g. copies.pathcopies() compares context objects for equality and
basectx.__eq__ compares the type. But since largefiles was dynamically
creating classes, they would all be unequal. That led pathcopies(),
after some changes I made, to not short-circuit to get copy info only
from the dirstate. This patch fixes that short-circuiting (and other
places where context are being compared for equality).

check that stat information such as mtime is preserved on rename - it's unclear
whether the `touch` and `stat` commands are portable, so we mimic them using
python. Not all platforms support precision of even one-second granularity, so
we allow a rather generous fudge factor here; 1234567890 is 2009, and the
primary thing we care about is that it's not the machine's current time;
hopefully it's really unlikely for a machine to have such a broken clock that
this test fails. :)
$ mkdir mtime
Create the file (as empty), then update its mtime and atime to be 1234567890.
>>> import os
>>> filename = "mtime/f"
>>> mtime = 1234567890
>>> open(filename, "w").close()
>>> os.utime(filename, (mtime, mtime))
$ hg ci -qAm 'add mtime dir'
"hg cp" does not preserve the mtime, so it should be newer than the 2009
timestamp.
$ hg cp -q mtime mtime_cp
>>> from __future__ import print_function
>>> import os
>>> filename = "mtime_cp/f"
>>> print(os.stat(filename).st_mtime < 1234567999)
False
"hg mv" preserves the mtime, so it should be ~equal to the 2009 timestamp
(modulo some fudge factor due to not every system supporting 1s-level
precision).
$ hg mv -q mtime mtime_mv
>>> from __future__ import print_function
>>> import os
>>> filename = "mtime_mv/f"
>>> print(os.stat(filename).st_mtime < 1234567999)
True
