This adds a couple of special cases
to stop the fuzzer from timing out.
The first occurs when the fuzzer generates
a very large path with very large quads.
Count the subdivisions and stop after a while.
The second occurs with a normal path and
1D path effect with a very small advance.
Count the points and stop after a while.

change int to unsigned (just make it uniform,
part of it was already unsigned)
change path by pointer to path by value
since it will be copied on write; fixes bug
where path changes from underneath measure
Allow empty paths to still initialize measure state.
This fixes the GM failure from the earlier check-in attempt
in CL 113269.

Path measure cannot use the same code approach for quadratics
and cubics. Subdividing cubics repeatedly does not result in
subdivided t values, e.g. a quarter circle cubic divided in
half twice does not have a t value equivalent to 1/4.
Instead, always compute the cubic segment from a pair of
t values.
When finding the length of the cubic through recursive measures,
it is enough to carry the point at a given t to the next
subdivision.
(Chrome suppression has landed already.)
