Remove redundant methods from the API

A bunch of redundant methods have been removed from the external API.

- All the reference/tag creation methods with `_f` are gone. The force
flag is now passed as an argument to the normal create methods.

- All the different commit creation methods are gone; commit creation
now always requires a `git_commit` pointer for parents and a `git_tree`
pointer for tree, to ensure that corrupted commits cannot be generated.

- All the different tag creation methods are gone; tag creation now
always requires a `git_object` pointer to ensure that tags are not
created to inexisting objects.
