It has been pointed out that the wording of the license of this library is
not entirely clear.
The term "dual licensing" usually refers to a licence choice of two
licenses "LICENSE1 _or_ LICENSE2.
Instead the license of this library claimed "LICENSE1 _and_ LICENSE2".
After an internal discussion with @metajack and @pasis it was made clear
that the initial idea was to dual license the library in the usual way.
This was also made clear by jack on the ML in the past [0].
As of jack, these licensing terms originated from jquery, which also used
the 'and' version in the past and has since been corrected [1].
This patch changes the license terms to 'MIT or GPLv3' and also adds SPDX
headers [2].

Before this change the user had to provide a password callback, even if the
PKCS#12 encoded file has no or an empty password.
This changes the behavior, so we first try to open the file without a
password and only then ask the user to provide one.
This fixes#204.

The cache is stored per connection object and is cleared on
* entry of wrong password
* release of connection object
* successful connection
It can be configured that libstrophe retries the password entry in case
the user entered a wrong password.

In order to be able to load password-protected key files a password
callback was added.
This also adds support for PKCS#12 containers instead of certificate+key.
