Mike Aizatsky 95149921b2 [sancov] improved object files handling. 
Multi-dso programs result in multiple coverage files dumped of the form
'<module_name>.<pid>.sancov'. When analyzing these coverage files it is
important to use correct corresponding object file.

This change removes the "-obj" sancov flag and lets user specify object
file names alongside coverage files. Sancov tool would match them using
<module_name> part of coverage file and short file name of the object
file.

from all outputs. By default blacklist contains "fun:__sancov*" line.

Mike Aizatsky 0650e9b2b7 sancov -not-covered-functions.

To do this, addresses are first converted to function locations. Set
operations are used for function locations.
