md5_stream has moved to a new file, md5-stream.c, which didn't get imported into 
emacs:

    md5: Clarify module to source relation.

    * lib/md5-stream.c: New file, extracted from lib/md5.c.
    * lib/md5.c: Don't include stdlib.h, unlocked-io.h.
    (BLOCKSIZE, md5_stream): Moved to md5-stream.c.
    * lib/md5.h: Tweak.
    * modules/crypto/md5 (Files): Add lib/md5-stream.c.
    (configure.ac): Don't define GL_COMPILE_CRYPTO_STREAM.
    (Makefile.am): Arrange to compile md5-stream.c.
    (Link): Mention $(LIB_CRYPTO).
