[Qemu-devel] [PATCH v8 09/20] replay: provide and accessor for rr filename

[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.
