revlog: move entry documentation alongside new related constants
Accessing individual index-entry element is usually done using integer directly.
This is presumably for "performance reasons". However as the index entry gain
more and more element it seems useful to get the option to use symbolic constant
to access item, for both clarify and versatility. We will probably keep using
integer for performance critical path, but less critical code may start using
them now that they are declared.

====================================
Testing head checking code: Case C-4
====================================
Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.
This case is part of a series of tests checking this behavior.
Category C: case were the branch is only partially obsoleted
TestCase 4: 2 changeset branch, only the base is pruned
.. old-state:
..
.. * 2 changeset branch
..
.. new-state:
..
.. * old base is pruned
.. * 1 new unrelated branch
..
.. expected-result:
..
.. * push denied
