[7/7] tree.h API: remove "stage" parameter from read_tree_recursive()

Commit Message

Ævar Arnfjörð Bjarmason March 6, 2021, 7:34 p.m. UTC

The read_tree_recursive() function took a "stage" parameter that is
passed through as-is. As it turns out nothing used this parameter in a
way that they couldn't just move to the callback function they
defined, so let's get rid of it.

If anyone needs to pass such information in the future they can use
the "void *context" parameter.
