dagop: extract descendants() from revlog module
This method needs to be implemented in other storage backends and is
generic if we parameterize the functions for retrieving revision
numbers and parent revision numbers.
Let's extract it to dagop so backends don't need to reinvent the
wheel.
I'm not too worried about performance overhead of the extra function
call because I don't expect anyone to be calling descendants() in a
tight loop.

filelog: remove checkhash() (API)
It is unused.
While a caller may want to ask the store to validate the hash of some
provided text, since there are no in-core consumers of this method,
let's drop it for now.

filelog: remove revdiff() (API)
This proxy method is no longer used.
While it might be useful to query a storage backend for the delta
between any 2 revisions because the store could have a delta cached
and could compute it more efficiently than the caller calling
revision() twice in order to compute a delta, since nothing in core
is using this API now, I feel comfortable nuking it.

localrepo: define storage backend in creation options (API)
We add an experimental config option to define the storage backend
for new repositories. By default, it uses "revlogv1," which maps to
the current and only modern supported repository format.
We add a "backend" creation option to control which backend to
use. It defaults to using the value from the config option.
newreporequirements() will now barf if it sees a "backend" value
that isn't "revlogv1." This forces extensions to monkeypatch the
function to handle requirements derivation for custom backends.
In order for this to "just work," we factored out obtaining the
default creation options into its own function and made callers
of newreporequirements() responsible for passing in valid data.
Without this, direct callers of newreporequirements() wouldn't
get the proper results.

wireprotov2: derive "required" from presence of default value
If we define a default value for all optional arguments, we no
longer need to explicitly declare whether the argument is required.
Instead, we can derive it from the presence of a default value
callable.

localrepo: capture repo interface factory functions as lambas
Previously, the list would hold a reference to the original function
and attempting to wrap the module function via extension wouldn't
result in the wrapped function being called, completely undermining
the expected behavior.

extensions: new closehead module for closing arbitrary heads
``hg close-head`` allows closing arbitrary heads. It is equivalent to

cext: use modern buffer protocol in patches()
PyObject_AsCharBuffer() is part of the "Old Buffer Protocol," which
has been deprecated for years. Let's port away from it.
PyBuffer_GetBuffer() must be paired with PyBuffer_Release(), hence the
added "goto cleanup" in a failure case.
We don't bump the extension version because the API has not changed.

identify: only query remote bookmarks if needed
Instead of all the time when operating on a remote repo. This
perf regression was introduced in 15a79ac823e8, in 4.3.
This datahint method returns nothing for -Tjson, -Tpickle, -Tdebug
--config ui.formatdebug=true and --config ui.formatjson, so the
bookmarks won't show up. I don't know what these formatters are for.
plainformatter and templateformatter work properly, and the few other
uses of datahint should have the same kind of problem.
There is further weirdness where "--template '{node}'" is not enough
to avoid querying the bookmarks, you also need to pass --id or -q.

setup: ignore message about disabling 3rd party extensions because of version
I started getting into a bind recently when switching between py2 and py3
because switching requires a `make clean`, which kills __version__.py. But then
when running `make local`, it picks up the local hg.exe (MSYS seems to prefix
$PATH with '.'), which doesn't know its version. That causes it to emit a
warning about needing at least 4.3 to load evolve, which caused setup.py to fail
saying there is no working hg executable to figure out the version. If we can
ignore general extension import failures, we should be able to ignore this too.

I don't like to overwrite variables, especially not with a different

and, therefore, to name it well).
