Ensure that signature strings never overflow again

The signature module used to use large strings with the signatures
of all functions in a class. This can lead to an overflow in MSVC,
because the maximum string length funnily still is 32K unicode
characters.

This patch solves that by using a single string per function.
Instead of a huge string, a list of strings is passed to each class.

To prevent any runtime increase, the string list creation is deferred
until the actual usage. At initialization time only a ssize_t holding
the structure address is passed.

As a result, the signature module should be even slightly faster.
