[PATCH 00/12] test-lib: misc improvements

Various miscellaneous small and easy to review cleanups & fixes to the test libraries. This doesn't conflict with the current "seen" branch.

Ævar Arnfjörð Bjarmason (12):
  test-lib: remove check_var_migration
  test lib: change "error" to "BUG" as appropriate
  test-lib-functions: move test_set_index_version() to its user
  test-lib-functions: remove generate_zero_bytes() wrapper
  test libs: rename bundle helper to "lib-bundle.sh"
  test libs: rename gitweb-lib.sh to lib-gitweb.sh
  test-lib-functions: move function to lib-bitmap.sh
  t/.gitattributes: sort lines
  test libs: rename "diff-lib" to "lib-diff"
  test-lib-functions: remove bug-inducing "diagnostics" helper param
  test-lib-functions: assert correct parameter count
  test-lib-functions: split out {debug,path,text} helpers
