commit    c6f6646bb0bef315c3836f3f6909c24a985a8621
Author:   Michael Paquier <michael@paquier.xyz>
Date:     Wed Dec 14 00:51:19 2022 +0000
First released in: 16.0

    Remove SHA256_HMAC_B from scram-common.h
    
    This referred to the size of the buffers for k_ipad and k_opad in HMAC
    computations.  This is unused since e6bdfd9, where SCRAM has switched to
    the cryptohash routines for its HMAC calculations rather than its own
    maths.
