commit 7ddcbce353f5811a8967297eece3fdff7ae04f50
Author: Richard Kreckel <kreckel at ginac.de>
Date:   Tue Nov 15 00:08:28 2022 +0100

    Refactor internal calc_bound() routines.
    
    Reduce them to computation of absolute values of the polynomial's roots
    and document that this is known as Landau's inequality. The multiplication
    with a power of two is done by the caller.
    
    Also remove the internal fallback computation using the maxcoeff since
    this cannot happen. (In the worst case, there is only one non-zero
    coefficient 'a'. Then we compute sqrt(a^2) which is not smaller than a.
    Otherwise, we compute sqrt(a^2 + x) > a.)

commit d4a58b74cea7c813330aa7813d86713bee205d04
Author: Richard Kreckel <kreckel at ginac.de>
Date:   Mon Nov 14 23:13:21 2022 +0100

    Remove own definition of enable_if<B, T> in favor of...
    
    ...the definition provided by <type_traits> since C++11.

commit cdb367739f507337ef1aa5c973e4671c908cf361
Author: Richard Kreckel <kreckel at ginac.de>
Date:   Mon Nov 14 23:05:47 2022 +0100

    [DEBUG] Make some debug output operators compile in factor.cpp...
    
    ...for the case when somebody actually #defines DEBUGFACTOR. The operators
    must be in the same anonymous namespace in which umodpoly, upoly and upvec
    are typedef'ed. (I'm not really sure I understand why but that's what GCC
    and CLang are convinced of.)

commit cdce7eb2282dbb095e9ae079da371c78b7c5150e
Author: Richard Kreckel <kreckel at ginac.de>
Date:   Thu Oct 13 00:12:07 2022 +0200

    Optimize some use of CLN's expt_pos() function in factor().
    
    (Not that it's slow or mattered much, but why waste cycles?)
