When a reference exists on the server but not locally, 'got send' could fail to ignore this reference as intended, raising an error instead. Add a test case for this isssue.

In addition to the previous commit [c450903bc2] that plugged fetch and send leaks, free what would be the path entry's path member, which is leaked when attempting to add a duplicate. And in the fetch case, free refname and id when got_pathlist_insert() returns err. ok stsp@

As reported by Johannes Thyssen Tishman, 'got stage -p $binaryfile' iterates each hunk, and produces unexpected behaviour when answering 'y'. Instead, present the standard "Binary files differ" message and only allow staging (or unstaging or reverting) the entire binary file. Includes tests for stage -p but unstage and revert -p tests are still needed. tweak + ok stsp@

Fixes spurious "branch on server has a different ancestry" errors from 'got send' when the repository history contains merge commits.
