[PULL 25/37] replay: provide an accessor for rr filename

[Paolo Bonzini <pbonzini@redhat.com>]

From: Pavel Dovgalyuk <Pavel.Dovgaluk@ispras.ru>

This patch adds an accessor function for the name of the record/replay
log file. Adding an accessor instead of making variable global,
prevents accidental modification of this variable by other modules.
