RFR: JDK-8011136 - FileInputStream.available and skip inconsistencies

The FileInputStream.available() method can return a negative value when
the file position is beyond the endof afile. This is an unspecified
behaviour that has the potential to break applications that expect
available to return a value of 0 or greater. The
FileInputStream.skip(long) method allows a negative value as its
parameter. This conflicts with the specifications of InputStream and
They are both long standing behaviours. In the fix, available() has been
changed to only return 0 or positive values. And for the skip(long)
method, due to the compatibility concern, its behaviour will not be
changed. Instead, the related java specs are going to be changed to
describe its current behaviour.
Thanks for your review!
