4f0c475719 Add empty record tests
The previous commit changed how we handle out-of-context empty records.
This commit adds some tests for the various scenarios. There are three
tests:
1: Check that if we inject an out-of-context empty record then we fail
2: Check that if we inject an in-context empty record then we succeed
3: Check that if we inject too many in-context empty records then we fail.

255cfeacd8 Reject out of context empty records
Previously if we received an empty record we just threw it away and
ignored it. Really though if we get an empty record of a different content
type to what we are expecting then that should be an error, i.e. we should
reject out of context empty records. This commit makes the necessary changes
to achieve that.

c796e02152 Document the issue with threads and dlopen()
If using threads and OpenSSL is loaded via dlopen(), and subsequently
closed again via dlclose() *before* the threads are destroyed, then
OpenSSL will not free up the per thread resources. We need to document
this restriction, and provide some guidance on what to do about it.

I did some testing and discovered/verified a few of things (at least
this is the behaviour on Linux):

- Using OpenSSL via dlopen in a mutli-threaded app does leak memory if
threads are destroyed after dlcose() is called.
- In a single threaded environment, or if threads are destroyed prior to
dlclose() being called, then no memory is leaked
- Using the RTLD_NODELETE flag to dlopen solves the above problem
- Interestingly the OpenSSL atexit() handler gets called when dlclose()
is called rather than at application exit (I was worred that it might crash
if there was an atexit() handler for a function that has been unloaded)
- RTLD_NODELETE is a non-standard flag - but it does seem to be fairly
widely supported. As far as I could determine (via google), at least Linux,
Solaris, OpenBSD, FreeBSD, HP-UX all seem to support it.

I also tested on Windows (using LoadLibrary instead of dlopen and
FreeLibrary instead of dlclose) and experienced similar behaviour, except
that (AFAIK) there is no equivalent of RTLD_NODELETE on Windows.

ec772a817a Fix the directory target generation
The directories for the final products were never registered, it was
plain luck that intermediary files were in the same place and
registered the directory anyway.

Also, scripts are generated directly from source (binaries go through
intermadiary object files), so we need to explicitely make sure to
avoid registering the source directory unless it's an in source
build.

399944622d Fix DSA, preserve BN_FLG_CONSTTIME
Operations in the DSA signing algorithm should run in constant time in
order to avoid side channel attacks. A flaw in the OpenSSL DSA
implementation means that a non-constant time codepath is followed for
certain operations. This has been demonstrated through a cache-timing
attack to be sufficient for an attacker to recover the private DSA key.

0ad1d94df4 Add developer targets for each subdirectory we have something to build in
Previous build scheme allowed building just the stuff in one
subdirectory, like this:

    make -C crypto/aes

Because the unified only has a top-level Makefile, this is not
possible with it.  This change adds a replacement where each directory
we have something to build in becomes a target in its own right,
allowing building something like this:

    make crypto/aes

The exception is the directory test, because we already have such a
target.
