[Jeff Trawick]

been configured with -D Z_PREFIX, which redefines the token "deflate".
[Eric Covener]
*) mod_auth_digest: Use the secret when generating nonces in all cases and

problems if used with round robin load balancers). Don't regenerate the
secret on graceful restarts. PR 54637 [Stefan Fritsch]

from the HTTP_IN filter, parse chunks in a single pass with zero copy.
Reduce memory usage by 48 bytes per request. [Graham Leggett]

mutexes (Mutex)
- mod_cache: thundering herd lock directory
- mod_lbmethod_heartbeat, mod_heartmonitor: heartbeat storage file
- mod_ldap: shared memory cache
- mod_socache_shmcb, mod_socache_dbm: shared memory or dbm for cache
