Summary: Fixes for bugs in gnu.java.nio.channels.FileChannelImpl.read/write
Original Submission: The three argument read and write native methods may
throw IOException("Unexpected JNI error") when passed
a zero byte buffer (and length 0). This is because the
behaviour of the JNI GetByteArrayElements call is
unspecified for a zero length array, and some VMs treat
this as a JNI failure.
The patch also fixes a possible memory leak in 'read'
and a couple of possible segfaults in 'write', all caused
by incorrect error handling.

* native/jni/java-nio/gnu_java_nio_channels_FileChannelImpl.c
(Java_gnu_java_nio_channels_FileChannelImpl_read___3BII):
handle zero length reads, and fix associated memory leak
(Java_gnu_java_nio_channels_FileChannelImpl_write___3BII):
handle zero length writes, and fix error handling bugs.
