revlog: introduce a tiny mock of a revlog class
This will be used in various function doctest added in the next changesets.
The class seems small enough to live in the module directly.

revlog: _segmentspan computes the byte span of a segment
Refactor out this code to be used somewhere else in a next changeset

revlog: early return in _slicechunk when span is already small enough
If the full span is smaller than the minimum gap size we'll consider, we know we
won't do any slicing and we can return earlier.

revlog: early return in _slicechunk when density is already good
We don't need to do anything if we know we won't enter the second while loop.
Save the overhead of the first loop by returning earlier.

sparse-read: discard gap below 65K only
Testing on actual data shows that 65K is more efficient in both time and memory
than 256K.

sparse-read: target density of 50% instead of 25%
The target density value is wrong. The default target chain span is
4*text-length. However, the target max chain payload is 2*text-length. So
default target density should be 50% (2/4) not 25% (1/4).
