GitCachedRepository.sync() is slow due to executing 1 git process to retrieve changes from each changeset

Description

I noticed repository sync command for cached git repository with many commits is very slow on especially Windows while porting to Python 3. The command invokes GitChangeset.get_changes() to retrieve changes to create node_change records. The method executes git diff-tree -z -r -M <tree1> <tree2> each time.

We could use git diff-tree --stdin ... and reuse the process rather than executing each time. See [0b691b30d/jomae.git] for trunk with Python 3.

I'll post proposed changes for 1.0-stable and results of the improvement.

Milestone: 1.0.20 → next-dev-1.5.x

Re-targeting to 1.5dev because proposed changes are not small for stable branches.

Milestone: next-dev-1.5.x → 1.5.2

Assigning to 1.5.2 since the change in is the py3 branch.
