Use the new pipeline cipher capability to encrypt multiple records being
written out all in one go. Two new SSL/SSL_CTX parameters can be used to
control how this works: max_pipelines and split_send_fragment.

max_pipelines defines the maximum number of pipelines that can ever be used
in one go for a single connection. It must always be less than or equal to
SSL_MAX_PIPELINES (currently defined to be 32). By default only one
pipeline will be used (i.e. normal non-parallel operation).

split_send_fragment defines how data is split up into pipelines. The number
of pipelines used will be determined by the amount of data provided to the
SSL_write call divided by split_send_fragment. For example if
split_send_fragment is set to 2000 and max_pipelines is 4 then:
SSL_write called with 0-2000 bytes == 1 pipeline used
SSL_write called with 2001-4000 bytes == 2 pipelines used
SSL_write called with 4001-6000 bytes == 3 pipelines used
SSL_write_called with 6001+ bytes == 4 pipelines used

split_send_fragment must always be less than or equal to max_send_fragment.
By default it is set to be equal to max_send_fragment. This will mean that
the same number of records will always be created as would have been
created in the non-parallel case, although the data will be apportioned
differently. In the parallel case data will be spread equally between the
pipelines.

Implement aes128-cbc as a pipeline capable cipher in the dasync engine.
As dasync is just a dummy engine, it actually just performs the parallel
encrypts/decrypts in serial.

Add a flag to indicate that a cipher is capable of performing
"pipelining", i.e. multiple encrypts/decrypts in parallel. Also add some
new ctrls that ciphers will need to implement if they are pipeline capable.

- Only build & test two configurations. Make all the
  other build variants buildonly on gcc (clang on osx).
- Don't build with default clang at all on linux.
- Only use gcc-5 and clang-3.6 for the sanitizer builds. Re-running
  e.g. CONFIG_OPTS="shared" with them seems redundant.

Strictly speaking, it isn't stdio and file access which offend me here;
it's the fact that UEFI doesn't provide a strdup() function. But the
fact that it's pointless without file access is a good enough excuse for

It was unexpected that OpenSSL::Test::setup() should be called twice
by the same recipe.  However, that may happen if a recipe combines
OpenSSL::Test and OpenSSL::Test::Simple, which can be a sensible thing
to do.  Therefore, we now allow it.

Should it be needed because the recipes within a RAW section might
clash with those generated by Configure, it's possible to tell it
not to generate them with the use of OVERRIDES, for example:

    SOURCE[libfoo]=foo.c bar.c

    OVERRIDES=bar.o
    BEGINRAW[Makefile(unix)]
    bar.o: bar.c
        $(CC) $(CFLAGS) -DSPECIAL -c -o $@ $<
    ENDRAW[Makefile(unix)]

In some cases, one might want to generate some source files from
others, that's done as follows:

    GENERATE[foo.s]=asm/something.pl $(CFLAGS)
    GENERATE[bar.s]=asm/bar.S

The value of each GENERATE line is a command line or part of it.
Configure places no rules on the command line, except the the first
item muct be the generator file.  It is, however, entirely up to the
build file template to define exactly how those command lines should
be handled, how the output is captured and so on.
