cleanup resultant (from spielwiese)
removed static int intgcd(int,int) (use static long intgcd(long,long))
fix: debug messages optimized
chg: deleted some unused code
chg: joined precomputeLeadingCoeff from facFactorize.cc and facFqFactorize.cc
chg: deleted some unused variable
chg: made functions and variables for timings static
chg: added more timing infos to gcd functions
chg: added more timing infos to main factorization functions
chg: timing.h in libfac and factory now coincide
chg: switch to modular gcd if psr can get dense
chg: optimization of Hi computation
chg: use modular gcd explicitly in EZ GCD mod p
chg: content computation
chg: clear denominators of A before shifting
fix: memory leak
fix: removed unused variable/assignment
