Start warning on hidden API greylist
Insert checks into reflection, JNI and the verifier to print
a warning when greylisted methods are invoked and fields accessed.
We do this on actual access, because reflection allows to list
all methods/fields and simply listing a greylisted member would
print too many false positives.
Issuing a warning also sets a boolean flag in Runtime. This will
be made accessible through VMRuntime to the framework which will
issue a Toast on Activity start.
The change was tested with internal microbenchmarks of reflection
and those flagged one issue. Microbenchmark invoking a field getter
has regressed by 35%. We will profile this benchmark in detail and
consider options for improvement. Bug b/72482474 was created to track
progress.
