Durham Goode a0fdd80720 dirstate: rename drop to untrack
Summary:
dirstate.drop() is used in two different situations. 1. To make a
tracked file become untracked, and 2. To remove a file from the dirstate
entirely. In the treestate case, this difference matters, so let's split drop
into two functions, one to mark something as untracked, and the other to remove
it entirely.

In this first patch we just rename drop to untrack. The next patch will
introduce the new delete function.

# dirstatenonnormalcheck.py - extension to check the consistency of the
# dirstate's non-normal map
#
# For most operations on dirstate, this extensions checks that the nonnormalset
# contains the right entries.
# It compares the nonnormal file to a nonnormalset built from the map of all
# the files in the dirstate to check that they contain the same files.
