module: gem5stats: enable asynchronous origins in gem5 stats file

Currently, reset_origin() in the gem5stats module enables to virtually
truncate the existing dumps from the gem5 statistics file so that any
subsequent match() calls will apply only on new dumps. However, the
current implementation resets the origin of the stats file unilaterally,
without other clients knowing about it, hence leading to data being
lost.

This commits removes the reset_origin() method and provides a different
API to handle virtual truncatures in the stats file. Namely, the match()
method now takes a base_dump parameter letting clients specifiying from
which dump they want match() to apply. This feature could also be usefull
if someone wanted to add off-line processing features for statistics
files.
