Changes:
* bigint input operator does no longer set failbit if it encounters EOF at
the end of a number
* fixed operator/(T a, bigrational const& b) for T != bigrational and a == 0.
* fixed elliptic_curve<gf_element>::isomorphism_type(bigint&,
bigint&,
point< gf_element >&,
point< gf_element >&,
bool)
* fixed HNF documentation.
* fixed friend class declaration for param_desc.
* Several bugfixes and cleanups in the MPQS and Lanczos code of
single_factor<bigint>. (If the changes prove to be stable then
rational_factorization will delegate all MPQS calls to
single_factor<bigint> in further LiDIA releases.)
* fixed build files for use with autoconf 2.59 / automake 1.9.6.
* avoid fragile test of \pdfoutput in doc/{color.graphics}.cfg and use
typearea.sty rather than geometry.sty due to a broken geometry.sty shipped
with SuSE 10.0's teTeX 3.0.
* fixed rational_factorization::compose() to prune really all factors with
exponent 0.
* many further small fixes...
