Move libapps headers into their own directory

This got triggered by test/testutil.h including ../apps/opt.h.

Some compilers do all inclusions from the directory of the C file
being compiled, so when a C file includes a header file with a
relative file spec, and that header file also includes another header
file with a relative file spec, the compiler no longer follows.

As a specific example, test/testutil/basic_output.c included
../testutil.h.  Fine so far, but then, test/testutil.h includes
../apps/opt.h, and the compiler ends up trying to include (seen from
the source top) test/apps/opt.h rather than apps/opt.h, and fails.

The solution could have been to simply add apps/ as an inclusion
directory.  However, that directory also has header files that have
nothing to do with libapps, so we take this a bit further, create
apps/include and move libapps specific headers there, and then add
apps/include as inclusion directory in the build.info files where
needed.

Fix d2i_PublicKey() for EC keys

o2i_ECPublicKey() requires an EC_KEY structure filled with an EC_GROUP.

o2i_ECPublicKey() is called by d2i_PublicKey(). In order to fulfill the
o2i_ECPublicKey()'s requirement, d2i_PublicKey() needs to be called with
an EVP_PKEY with an EC_KEY containing an EC_GROUP.

However, the call to EVP_PKEY_set_type() frees any existing key structure
inside the EVP_PKEY, thus freeing the EC_KEY with the EC_GROUP that
o2i_ECPublicKey() needs.

This means you can't d2i_PublicKey() for an EC key...

The fix is to check to see if the type is already set appropriately, and
if so, not call EVP_PKEY_set_type().

Make sure we trigger retransmits in DTLS testing

During a DTLS handshake we may need to periodically handle timeouts in the
DTLS timer to ensure retransmits due to lost packets are performed. However,
one peer will always complete a handshake before the other. The DTLS timer
stops once the handshake has finished so any handshake messages lost after
that point will not automatically get retransmitted simply by calling
DTLSv1_handle_timeout(). However attempting an SSL_read implies a
DTLSv1_handle_timeout() and additionally will process records received from
the peer. If those records are themselves retransmits then we know that the
peer has not completed its handshake yet and a retransmit of our final
flight automatically occurs.

Build: use attributes to indicate installed script classes

We have two classes of scripts to be installed, those that are
installed as "normal" programs, and those that are installed as "misc"
scripts.  These classes are installed in different locations, so the
build file templates must pay attention.

Because we didn't have the tools to indicate what scripts go where, we
had these scripts hard coded in the build template files, with the
maintenance issues that may cause.  Now that we have attributes, those
can be used to classify the installed scripts, and have the build file
templates simply check the attributes to know what's what.

Furthermore, the 'tsget.pl' script exists both as 'tsget.pl' and
'tsget', which is done by installing a symbolic link (or copy).  This
link name is now given through an attribute, which results in even
less hard coding in the Unix Makefile template.

Rework building: Unix changes to handle extensions and product names

Add platform::Unix, which is a generic Unix module to support product
name and extensions functionlity.  However, this isn't quite enough,
as mingw and Cygwin builds are done using the same templates, but
since shared libraries work as on Windows and are named accordingly,
platform::mingw and platform::Cygwin were also added to provide the
necessary tweaks.

This reworks Configurations/unix-Makefile.tmpl to work out product
names in platform::Unix et al terms.  In this one, we currently do
care about the *_extension config attributes, and the modules adapt

This change also affected crypto/include/internal/dso_conf.h.in, since
the DSO extension is meant to be the same as the short shared library
extension, which isn't '.so' everywhere.

'.so.\$(SHLIB_VERSION_NUMBER)' are removed, platform::Unix provides

Fix a memory leak in the mem bio

If you use a BIO and set up your own buffer that is not freed, the
memory bio will leak the BIO_BUF_MEM object it allocates.

The trouble is that the BIO_BUF_MEM is allocated and kept around,
but it is not freed if BIO_NOCLOSE is set.

The freeing of BIO_BUF_MEM was fairly confusing, simplify things
so mem_buf_free only frees the memory buffer and free the BIO_BUF_MEM
in mem_free(), where it should be done.

Alse add a test for a leak in the memory bio
Setting a memory buffer caused a leak.
