[PATCH 0/3] Condition coverage docs, bugfix

["Jørgen Kvalsvik" <j@lambda.is>]

This patch set includes a memory leak fix and some documentation
additions for condition coverage. Without prior knowledge it would be
hard to find out what exactly gcc/gcov means by "condition coverage",
so I fleshed it out and made sure to include some searchable keywords --
masking, MC/DC. The flags leave room for other condition coverage
flavors, and relies on docs to make it clear.

Jørgen Kvalsvik (3):
  Release structures on function return
  Add section on MC/DC in gcov manual
  Use the term MC/DC in help for gcov --conditions
