Gilles Peskine 8f28c24b4a Explain the problem in more concrete terms
Don't try to make the reader guess what a “negative zero” might mean.

so remove the check for GNU grep.

Add library/*.h to the list of files scanned for enums in
list-enum-consts.sh, consistent with the changes made to
list-macros.sh.

This is needed to ensure that check-names.sh passes for the MPS

Gilles Peskine 5ef0b97f87 Don't comment out dependencies
This was a mistake, there's no reason for the dependencies to be
commented out. The dependencies on PSA_WANT_ALG_EDDSA aren't actually
necessary at the moment, but they might be in certain configurations
if some macros are simplified to save code size.

Gilles Peskine ff6a32d79c Fix low-probability arithmetic error in ECC
Fix the subtraction in fix_negative, which was incorrectly not looking
for a carry. This caused the result to be wrong when the least
significant limb of N was 0. Fix #4296.

The bug was introduced by d10e8fae9e
"Optimize fix_negative". Thanks to Philippe Antoine (catenacyber) for
reporting the bug which was found by his EC differential fuzzer.

Gilles Peskine 80f56733b0 Fix and simplify sign handling in mbedtls_mpi_read_string
Move the handling of the sign out of the base-specific loops. This
both simplifies the code, and corrects an edge case: the code in the
non-hexadecimal case depended on mbedtls_mpi_mul_int() preserving the
sign bit when multiplying a "negative zero" MPI by an integer, which
used to be the case but stopped with PR #2512.

Fix #4295. Thanks to Guido Vranken for analyzing the cause of the bug.
