From: Derrick Stolee <dstolee@xxxxxxxxxxxxx>
In order to remove index compatibility macros cleanly, we relied upon
static globals 'repo' and 'istate' to be pointers to the_repository and
the_index, respectively. We can now start reducing the need for these
static globals by modifying method prototypes to use them when
necessary.
Move these static globals further down in the file so we can identify
which method only need to add a 'struct index_state *istate' parameter.
The only changes included here adjust method prototypes and their call
locations.
