During the trace generation, we can enable the bounds check, which
catches all events that are monitored by the generic-experiement
options:
--catch-write-textsegment
--catch-upper-outerspace
--catch-lower-outerspace
The generic experiment set the TriggerAccessType not the
WatchAccessType. Therefore, the text segment listener fired on write
AND read events. The watch access type can only be set in the constructor.
This patch uses ELF segments instead of section for determining the
extent of the binary in memory. Consequently, the outerspace listener
was modified to use these new bounds. Additionally, the generic
experiment was changed to include a lowerspace listener, which listens
for write access below the physical memory location of the ELF.
