bookmark: split out target computation from 'deletedivergent'

We want to use applychanges in order to unify bookmark movement. We need a way
to compute divergence deletion without actually removing them.

We split the function in two in this patch while we migrate the existing users
of this code on next patches.

struct bdiff_hunk {

	struct bdiff_hunk *next;

int bdiff_splitlines(const char *a, ssize_t len, struct bdiff_line **lr);
int bdiff_diff(struct bdiff_line *a, int an, struct bdiff_line *b, int bn,
	struct bdiff_hunk *base);
