302f75887e Attempt to log an error if init failed
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.

0fc32b0718 The new init functions can now fail so shouldn't be void
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.

8bd8221be8 Variable was declared static when it shouldn't be
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.

dd27f16e9a Can't re-init after stop.
Remoce DYANMIC once-init stuff.
After the library is stopped, you can't restart it.

deca5df2fb If we've not been inited don't deinit
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.

b7326ea710 NULL the thread_local_inits_st pointer after use
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.

b184e3ef73 Provide framework for auto initialise/deinitialise of the library
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).
