Message:

Preparing the removal of Frank's p_Monic/p_Gcd/p_ExtGcd from common use

chg: moved most of the functions (with helpers) into algext.cc and made them static

NOTE: p_PolyDiv stayed in p_polys.cc as it is used in convFactoryASingA
NOTE: p_ExtGcd also is made public via algext.h (needed elsewhere?)
