If init failed we'd like to set an error code to indicate that. But if
init failed then when the error system tries to load its strings its going
to fail again. We could get into an infinite loop. Therefore we just set
a single error the first time around. After that no error is set.

The new init functions can fail if the library has already been stopped. We
should be able to indicate failure with a 0 return value.

The local variable tmp was declared static when it shouldn't be. This
is in the no-threads implementation, and it was immediately initialised
to something else on every invokation of the function so it doesn't break
anything...but still shouldn't be there.

After the library is stopped, you can't restart it.

If you call an explicit deinit when we've not been inited then a seg
fault can occur. We should check that we've been inited before attempting
to deinit.

After the final use of the thread_local_inits_st we should ensure it is
set to NULL, just in case OPENSSL_INIT_thread_stop gets called again and
it tries to use garbage.

This builds on the previous commit to auto initialise/deinitialise
libcrypto.
Reviewed-by: NRichard Levitte <levitte@openssl.org>

This commit provides the basis and core code for an auto initialisation
and deinitialisation framework for libcrypto and libssl. The intention is
to remove the need (in many circumstances) to call explicit initialise and
deinitialise functions. Explicit initialisation will still be an option,
and if non-default initialisation is needed then it will be required.
Similarly for de-initialisation (although this will be a lot easier since
it will bring all de-initialisation into a single function).
