Java binding for SAS

Fix / missing free() on some errors


Added doc regarding string encoding for keys


cleaning

The SAS header is required to build the package therefore it needs to be
shipped with the source distribution of the package.

Adding it to the manifest achieves this.

because older versions of emscripten don't support the length argument to
UTF8ToString.

The Pointer_stringify() function is deprecated and has a couple of
issues because it tries to guess the encoding of the buffer. In some
cases it can ignore the length parameter which could end up in
inconsistencies.

Switch to UTF8toString() that takes a length parameter and respects,
that way we don't need to allocate an additional byte for a NULL byte.

This allows downstream users to install this python module with pip as
well as allowing people to declare it as a dependency in their setup.py.

This patch adds the Olm header files to the manifest, this results in
the header files being added to source distributions of the python-olm
module.

The headers are required to build the module. Including them in the
source distribution is the easiest way to make sure that builds from the
source distribution will succeed provided that the Olm C library is
already installed.

This patch adds bindings to the PK part of the Olm library contained in
the pk.h header file.

Encryption, decryption as well as pickling/unpickling of the decryption
object is supported.

Typing is part of standard library from python 3.5 and from python 3.7
onwards trying to install it results in an error.

This patch disables typing installation on python versions that are
newer than 3.5.

Add signing class to the pk module

because emscripted has dropped support for the old flag and us
setting it is now breaking the build.

This is a workaround for a bug where signature verification would
overwrite the variable holding the signature.

This only happens on python2.
