bundle2: only seek to beginning of part in bundlerepo

For reasons still not yet fully understood by me, bundlerepo
requires its changegroup bundle2 part to be seeked to beginning
after part iteration. As far as I can tell, it is the only
bundle2 part consumer that relies on this behavior.

This seeking was performed in the generic iterparts() API. Again,
I don't fully understand why it was here and not in bundlerepo.
Probably historical reasons.

What I do know is that all other bundle2 part consumers don't
need this special behavior (assuming the tests are comprehensive).
So, we move the code from bundle2's iterparts() to bundlerepo's
consumption of iterparts().

# Extract version number into 4 parts, some of which may be empty:
#
# version: the numeric part of the most recent tag. Will always look like 1.3.
#
# type: if an rc build, "rc", otherwise empty
#
# distance: the distance from the nearest tag, or empty if built from a tag
#
# node: the node|short hg was built from, or empty if built from a tag
