treewide: replace maybe_tree with accessor methods

Browse Source 
In anticipation of making trees load lazily, create a Coccinelle
script (contrib/coccinelle/commit.cocci) to ensure that all
references to the 'maybe_tree' member of struct commit are either
mutations or accesses through get_commit_tree() or
get_commit_tree_oid().

Apply the Coccinelle script to create the rest of the patch.
