collect line type metadata when generating diff
Similar to line offsets, create an array of line types (i.e., hunk, context, minus, plus) for each line output in the diff. ok stsp@
avoid writing just one character at a time in diff_output_lines()

allow for telling the difference between empty and non-existent files
Adjust labels used in diff output accordingly; non-existent files should have the label "/dev/null"
allow diff API users to atomize files separately
This is a breaking API change (not that we care about that at this point). This can avoid redundant work spent on atomizing a file multiple times. There are use cases where one particular file must be compared to other files over and over again, such as when blaming file history. The old API gave access to both versions of the file to the atomizer just in case a future atomizer implementation needs this. This can still be achieved by passing a second file via the atomizer's private data pointer.
print "\ No newline at end of file" message like UNIX diff(1) does
Not adding new tests since this behaviour is covered by tests in Got.
rename diff_atom->d to diff_atom->root, because it always is
The idea was that for each diff box within the files, the atoms would have a backpointer to the current layer of diff_data (indicating the current section), but it is not actually needed to update the backpointer in each atom to the current diff_data. That is why the current code always points atom->d to the root diff_data for the entire file. Clarify by proper name. Constructs like atom->d->root->foo are redundant, just use atom->root->foo.
