core: Link all context objects and add _gpgme_get_ctx.

* src/context.h (struct gpgme_context): Add field 'next_ctx'.
* src/gpgme.c (def_lc_lock): Replace by ...
(context_list_lock): new.
(context_list): New variable.
(gpgme_new): Add new context object to the list.
(gpgme_release): Remove context object from the list.
(_gpgme_get_ctx): New function.

To allow mapping a context serial number back to a context object and
to check whether a serialno has still a context object, we need to
link them all together.  We already take a lock to setup the locale
and thus the only overhead is in freeing the context.
