[Bug general/4827] New: Merge MemorySpaceByteBuffer and AddressSpaceByteBuffer

[mark at klomp dot org]

frysk-core should use one method of accessing memory spaces.
MemorySpaceByteBuffer is really just an optimization of AddressSpaceByteBuffer
(in the case of AddressSpace.TEXT/DATA) and all code should go through the
optimized path (StateLessFile) for accessing memory if the AddressSpace allows
it. So I am going to merge the two (and fix up the places that currently use the
slow path).
LogicalMemoryByteBuffer should be implemented on top of this.

    * AddressSpaceByteBuffer.java (mem): New field.
    (pokesRequest): Likewise.
    (AddressSpaceByteBuffer): Initialize mem and pokesRequest.
    (PeeksRequest.peek): New method.
    (PeeksRequest.execute): use peek().
    (PeeksRequest.request): Likewise.
    (PokesRequest): New inner class.
    (poke): New method.
