Bugfix
   * Fix undefined behavior (typically harmless in practice) when some bignum
     functions receive the most negative value of mbedtls_mpi_sint. Credit
     to OSS-Fuzz. Fixes #6597.
Fix undefined behavior with the most negative mbedtls_mpi_sint When x is the most negative value of a two's complement type, `(unsigned_type)(-x)` has undefined behavior, whereas `-(unsigned_type)x` has well-defined behavior and does what was intended.
