Remove ignored files from the working directory if they were stashed
pack-objects: free memory safely

A few fixes have accumulated in this area which have made the freeing of
data a bit muddy. Make sure to free the data only when needed and once.

When we are going to write a delta to the packfile, we need to free the
data, otherwise leave it. The current version of the code mixes up the
checks for po->data and po->delta_data.

examples/diff: Add minimal, patience diff options.

- Add minimal, patience diff options to diff example. libgit2
  `diff_xdiff.git_xdiff_init` already supports these flags, so
  no additional change is necessary.
- Remove minimal and patience flag addition from project list.
Fixed missing error check on call to git_remote_download in git_remote_fetch. Moved error check to statement following git_remote_disconnect so that the disconnect happens regardless of the result of the download call.
