       +Replace FILE BIO's with dummy ops that fail.
       +Include <stdio.h> for sscanf() even with no-stdio (since the declaration
        is there). We rely on sscanf() to parse the OPENSSL_ia32cap environment
        variable, since it can be larger than a 'long'. And we don't rely on the
        availability of strtoull().
       +Remove OPENSSL_stderr(); not used.
       +Make OPENSSL_showfatal() do nothing (currently without stdio there's
        nothing we can do).
       +Remove file-based functionality from ssl/. The function
        prototypes were already gone, but not the functions themselves.
       +Remove unviable conf functionality via SYS_UEFI
       +Add fallback definition of BUFSIZ.
       +Remove functions taking FILE * from header files.
       +Add missing DECLARE_PEM_write_fp_const
       +Disable X509_LOOKUP_hash_dir(). X509_LOOKUP_file() was already compiled out,
        so remove its prototype.
       +Use OPENSSL_showfatal() in CRYPTO_destroy_dynlockid().
       +Eliminate SRP_VBASE_init() and supporting functions. Users will need to
        build the verifier manually instead.
       +Eliminate compiler warning for unused do_pk8pkey_fp().
       +Disable TEST_ENG_OPENSSL_PKEY.
       +Disable GOST engine as is uses [f]printf all over the place.
       +Eliminate compiler warning for unused send_fp_chars().
