[Bug general/4390] New: CorefileByteBuffer needs to use a lighter weight file access method than RandomAccessFile

["pmuldoon at redhat dot com" <sourceware-bugzilla@sourceware.org>]

A read from a corefile should be open->read->close. Doing this with
RandomAccessFile would cause many dozens of java objects queued for GC on a lot
of peek() operations. Right now, because of that, CorefileBytebuffer maintains
the RandomAccessFile open for the life of the buffer, consuming one FD for a
long time.

A very light weight object that keeps the file closed, opens it on read, then
closes it again is required, so that fd's and other systems resources can be
cycled back into the pool
