Uses separate locks for socket read and write operations. While holding the
socket reader lock, a different thread can still claim the socket write lock.
This allows to asynchronously send event messages while holding the read
lock.
During shutdown, waiting for callbacks might never complete, as queued
callbacks might not get executed under certain conditions. Not the clean fix,
but works good enough for now.
Seen on Windows in vici tests.
While we don't add FDs with an active callback to the watched FDSET, we still
can get notifications for callbacks active due the asynchronous processing
of the same.
To avoid queue multiple callbacks, we check for queued callbacks before
activating new ones.
Using the same mechanism as the METHOD macro, the CALLBACK macro defines
a hybrid function signature. It strictly uses a weak void* for the first
function parameter, in contrast to the dynamic METHOD object "this" type.
This solves a problem with GNAT when compiling charon-tkm as __atomic*
built-ins are only provided in GCC 4.7 and newer.
Currently GNAT 4.6 and GCC 4.7.2 is shipped with Debian wheezy (stable),
as used in the testing environment. So while the configure script correctly
detected the __atomic* built-ins, and defined HAVE_GCC_ATOMIC_OPERATIONS,
this define turned out to be incorrect when charon-tkm was later built
with GNAT.
aikgen outputs a binary AIK private key blob and the AIK public key.
Optionally the Identity Request encrypted with the public key of
the Privacy CA can be output.
tests.load and tests.plugindir to allow the specification of the plugins
to be loaded and the directory to load them from.

By setting the environment variable TESTS_STRONGSWAN_CONF, the unit tests can
be asked to load a configuration file, thus enabling the tester to make use of
the usual configuration settings.
