Unsued printing functionality. If something should need this we can readily
add it back.

These can now use the internal version of BN_bn2hex() and be direct
wrappers of BIO_printf() and fprintf() as they should have been all
along.

We no longer need to do weird things as taking the length of the hex
string and jumping over a sign we didn't need.

The reason the function this replaces is called ASN1_bn_print() is that it
actually prints a representation of the ASN.1 encoding.

Add bn_printf(), a replacement for ASN1_bn_print()2023-07-06T14:37:39+00:00tb2023-07-06T14:37:39+00:00urn:sha1:ee3f95b4025c8b7b71816169b6d63a3d1e8c060f
ASN1_bn_print() will be removed in an upcoming bump. This adds an internal
API that covers the same functionality but doesn't require that the caller
pass in a sufficiently large scratch space that ASN1_bn_print() may or may
not use. In addition, this takes a format string, which allows us to ditch
some extra dances.

Rename the largely misnamed bn_print.c to bn_convert.c2023-04-14T11:10:11+00:00jsing2023-04-14T11:10:11+00:00urn:sha1:7ca808a18fa4df8ca8a7e98efb13a2489b0489b3
This file primarily contains the various BN_bn2*() and BN_*2bn() functions
(along with BN_print() and BN_options()). More function shuffling will
follow.

Avoid negative zero.2023-02-13T04:25:37+00:00jsing2023-02-13T04:25:37+00:00urn:sha1:53aa84bf6a4cfaffa003a28a5651a7f30bd74400
Whenever setting negative to one (or when it could potentially be one),
always use BN_set_negative() since it checks for a zero valued bignum and
will not permit negative to be set in this case. Since BN_is_zero()
currently relies on top == 0, call BN_set_negative() after top has been
set (or bn_correct_top() has been called).
This fixes a long standing issue where -0 and +0 have been permitted,
however multiple code paths (such as BN_cmp()) fail to treat these as
equivalent.
Prompted by Guido Vranken who is adding negative zero fuzzing to oss-fuzz.
