If RAND_add wraps around, XOR with existing. Add test to drbgtest that
does the wrap-around.

Re-order seeding and stop after first success.

Add RAND_poll_ex()

Use the DF and therefore lower RANDOMNESS_NEEDED.  Also, for child DRBG's,
mix in the address as the personalization bits.

Centralize the entropy callbacks, from drbg_lib to rand_lib.
(Conceptually, entropy is part of the enclosing application.)
Thanks to Dr. Matthias St Pierre for the suggestion.

Various code cleanups:
    -Make state an enum; inline RANDerr calls.
    -Add RAND_POLL_RETRIES (thanks Pauli for the idea)
    -Remove most RAND_seed calls from rest of library
    -Rename DRBG_CTX to RAND_DRBG, etc.
    -Move some code from drbg_lib to drbg_rand; drbg_lib is now only the
     implementation of NIST DRBG.
    -Remove blocklength

File::Glob::glob is deprecated, it's use generates this kind of
message:

    File::Glob::glob() will disappear in perl 5.30. Use File::Glob::bsd_glob() instead. at ../master/Configure line 277.

So instead, use a construction that makes the caller glob() use
File::Glob::bsd_glob().

Note that we're still excluding VMS, as it's directory specs use '['
and ']', which have a different meaning with bsd_glob and would need
some extra quoting.  This might change, but later.

This meant:
* renaming register_tests to setup_tests and giving it a success/failure return.
* renaming the init_test function to setup_test_framework.
* renaming the finish_test function to pulldown_test_framework.
* adding a user provided global_init function that runs before the test frame

* adding helper functions that permit tests to access their command line args.

OpenSSL already has the feature of SSL_MODE_RELEASE_BUFFERS that can
be set to release the read or write buffers when data has finished
reading or writing. OpenSSL will automatically re-allocate the buffers
as needed. This can be quite aggressive in terms of memory allocation.

This provides a manual mechanism. SSL_free_buffers() will free
the data buffers if there's no pending data. SSL_alloc_buffers()
will realloc them; but this function is not strictly necessary, as it's
still done automatically in the state machine.

This is an implementation of a BIO filter that produce TAP compatible output
for the test framework.  The current test indentation level is honoured.

The test output functions have been modified to not attempt to indent
their output and to not include the leading '#' character.

The filter is applied to bio_err only.  bio_out is left unchanged, although
tests using bio_out have been modified to use bio_err instead.
