Make SkPngCodec support rewinding properly.

Separate out the code for reading the header, and use it to reinitialize
fPng_ptr and fInfo_ptr after a rewind.

Use common code to clean up fPng_ptr and fInfo_ptr, and set them to
NULL and treat them as NULL as appropriate.

Update the test to expect SkPngCodec to succeed.
