bundlerepo: fix mismatches with repository and revlog classes
Both pytype and PyCharm complained that `write()` and `_write()` in the
bundlephasecache class aren't proper overrides- indeed they seem to be missing
an argument that the base class has.
PyCharm and pytype also complained that the `revlog.revlog` class doesn't have a
`_chunk()` method. That looks like it was moved from revlog to `_InnerRevlog`
back in
e8ad6d8de8b8, and wasn't caught because this module wasn't type checked.
However, I couldn't figure out a syntax with `revlog.revlog._inner._chunk(self, rev)`,
as it complained about passing too many args. `bundlerevlog._rawtext()` uses
this `super(...)` style to call the super class, so hopefully that works, even
with the wonky dynamic subclassing. The revlog class needed the `_InnerRevlog`
field typed because it isn't set in the constructor.
Finally, the vfs type hints look broken. This initially failed with:
File "/mnt/c/Users/Matt/hg/mercurial/bundlerepo.py", line 65, in __init__: Function readonlyvfs.__init__ was called with the wrong arguments [wrong-arg-types]
Expected: (self, vfs: mercurial.vfs.vfs)
Actually passed: (self, vfs: Callable)
Called from (traceback):
line 232, in dirlog
line 214, in __init__
I don't see a raw Callable, but I tried changing some of the vfs args to be typed
as `vfsmod.abstractvfs`, but that class doesn't have `options`, so it failed
elsewhere. `readonlyvfs` isn't a subclass of `vfs` (it's a subclass of
`abstractvfs`), so I'm not sure how to handle that. It would be a shame to have
to make a union of vfs subclasses (but not all of them have `options` either).
#require symlink
Create extension that can disable symlink support:
$ cat > nolink.py <<EOF
> from mercurial import extensions, util
> def setflags(orig, f, l, x):
> pass
> def checklink(orig, path):
> return False
> def extsetup(ui):
> extensions.wrapfunction(util, 'setflags', setflags)
> extensions.wrapfunction(util, 'checklink', checklink)
> EOF

Simulate a checkout shared on NFS/Samba:

$ hg --config extensions.n=$TESTTMP/nolink.py status --debug

Make a clone using placeholders:
$ hg --config extensions.n=$TESTTMP/nolink.py clone . ../win-repo

$ cd ../win-repo

$ hg --config extensions.n=$TESTTMP/nolink.py st --debug
Empty placeholder:
$ rm b
$ touch b
$ hg --config extensions.n=$TESTTMP/nolink.py st --debug

Write binary data to the placeholder:
>>> open('b', 'w').write('this is a binary\0') and None
$ hg --config extensions.n=$TESTTMP/nolink.py st --debug

Write a long string to the placeholder:
>>> open('b', 'w').write('this' * 1000) and None
$ hg --config extensions.n=$TESTTMP/nolink.py st --debug
ignoring suspect symlink placeholder "b"
