factor arbitrarily large numbers
* m4/gmp.m4: New file; adds cu_GMP, which detects GNU MP.
* configure.ac: Use cu_GMP.
* src/Makefile.am: Link factor against libgmp if available.
* src/factor.c: Use GNU MP if it is available.
(emit_factor, emit_ul_factor, factor_using_division,
factor_using_pollard_rho, extract_factors_multi,
sort_and_print_factors, free_factors): new functions
for the arbitrary-precision implementation, taken from an example
in GNU MP.
(factor_wheel): Renamed; was called factor.
(print_factors_single): Renamed; was called print_factors.
(print_factors): New function, chooses between the single- and
arbitrary-precision algorithms according to availability of GNU MP
and the length of the number to be factored.
(usage, main): New options --bignum and --no-bignum.
* coreutils.texi (factor invocation): Document new command-line
options for the MP implementation and update the performance
numbers to take into account the asymptotically faster algorithm.
* TODO: Remove item about factoring large primes (it's done).
* m4/gmp.m4: Add support for --without-gmp.
* NEWS: Mention the new feature.
