sshpeer: make pipe polling code more explicit
"hasbuffer" is a property on our special bufferedinputpipe class.
When reading this code, I thought it might have had something
special to do properties on built-in types. But "hasbuffer" doesn't
appear in the CPython code base for either 2.7 or 3.7, so the
answer is no.
Let's make the code more explicit about the fact that it deals with
our special bufferedinputpipe type.

Testing obsolescence markers push: Cases B.3
============================================
Mercurial pushes obsolescences markers relevant to the "pushed-set", the set of
all changesets that requested to be "in sync" after the push (even if they are
already on both side).
This test belongs to a series of tests checking such set is properly computed
and applied. This does not tests "obsmarkers" discovery capabilities.
Category B: pruning case
TestCase 3: Pruned changeset on non-pushed part of the history
B.3 Pruned changeset on non-pushed part of the history
