discovery-helper: use reflink copy if available
A reflink copy will copy the files "as usual" but keep using the same data block
underneath. This is only supported by "copy on write" file system like btrfs or
zfs.
This will achieve similar performance that the existing hardlink clone that
Mercurial performs with the same initial space saving. However, it will behave
better on revlogs start being touch by strip. Instead of duplicating all data in
the touched revlogs, only the block actually affected by the strip will be
duplicated. This save a lot of space when building many variants of large
repositories.
The --reflink=always flag make sure the `cp` call fails if reflink copies are
not supported. Falling back to local clone.

Error is handled reasonably. We override the phabtoken here so that
when you're developing changes to phabricator.py you can edit the
above config and have a real token in the test but not have to edit
this test.
$ hg phabread --config auth.hgphab.phabtoken=cli-notavalidtoken \
> --test-vcr "$VCR/phabread-conduit-error.json" D4480 | head
abort: Conduit Error (ERR-INVALID-AUTH): API token "cli-notavalidtoken" has the wrong length. API tokens should be 32 characters long.
Basic phabread:

# HG changeset patch
exchangev2: start to implement pull with wire protocol v2
Wire protocol version 2 will take a substantially different
approach to exchange than version 1 (at least as far as pulling
is concerned).
This commit establishes a new exchangev2 module for holding
code related to exchange using wire protocol v2. I could have
added things to the existing exchange module. But it is already
phabupdate with an accept:
$ hg phabupdate --accept D4564 \
> -m 'I think I like where this is headed. Will read rest of series later.'\
> --test-vcr "$VCR/accept-4564.json"
