manual: - adding aggregate passing and returning info for x64 (win and sysv, however, *only* w/ respect to types supported by dyncall) - python binding text cleanup and sync with current binding version - added suite_aggrs description and cleaned up other test suite descriptions a bit - update list of calling convention modes - cleanup and minor other fixes (e.g. changed \newpage in many places to \clearpage to avoid hitting float limit, crlf->cr, ...)

-\section{\emph{Dyncallback} C library API}
-
-This library extends \product{dyncall} with function callback support, allowing
-the user to dynamically create a callback object that can be called directly,
-or passed to functions expecting a function-pointer as argument.\\
-\\
-Invoking a \product{dyncallback} calls into a user-defined unified handler that 
-permits iteration and thus dynamic handling over the called-back-function's
-parameters.\\
-\\
-The flexibility is constrained by the set of supported types, though.\\
-\\
-For style conventions and supported types, see \product{dyncall} API section.
-In order to use \product{dyncallback}, include {\tt "dyncall\_callback.h"}.
-
-\subsection{Callback Object}
-
-The \emph{Callback Object} is the core component to this library.
-
-\paragraph{Types}
-
-\begin{lstlisting}[language=c]
-typedef struct DCCallback DCCallback;
-\end{lstlisting}
-
-\paragraph{Details}
-The \emph{Callback Object} is an object that mimics a fully typed function
-call to another function (a generic callback handler, in this case).\\
-\\
-This means, a pointer to this object is passed to a function accepting a pointer
-to a callback function \emph{as the very callback function pointer itself}.
-Or, if called directly, cast a pointer to this object to a function pointer and
-issue a call.
-
-
-\subsection{Allocation}
-
-\paragraph{Functions}
-
-\begin{lstlisting}[language=c]
-DCCallback* dcbNewCallback(const char*        signature,
-                           DCCallbackHandler* funcptr,
-                           void*              userdata);
-void dcbFreeCallback(DCCallback* pcb);
-\end{lstlisting}
-
-\lstinline{dcbNewCallback} creates and initializes a new \emph{Callback} object,
-where \lstinline{signature} is the needed function signature (format is the
-one outlined in the language bindings-section of this manual, see Table \ref{sigchar})
-of the function to mimic, \lstinline{funcptr} is a pointer to a callback handler,
-and \lstinline{userdata} a pointer to custom data that might be useful in the
-handler.
-Use \lstinline{dcbFreeCallback} to destroy the \emph{Callback} object.\\
-\\
-As with \capi{dcNewCallVM}/\capi{dcFree}, this will allocate memory using the
-system allocators or custom overrides.
-
-
-\subsection{Callback handler}
-
-The unified callback handler's declaration used when creating a \capi{DCCallback}
-is:
-
-\begin{lstlisting}
-char cbHandler(DCCallback* cb,
-               DCArgs*     args,
-               DCValue*    result,
-               void*       userdata);
-\end{lstlisting}
-
-\capi{cb} is a pointer to the \capi{DCCallback} object in use, \capi{args} allows
-for dynamic iteration over the called-back-function's arguments (input) and
-\capi{result} is a pointer to a \capi{DCValue} object in order to store the
-callback's return value (output, to be set by handler).\\
-Finally, \capi{userdata} is a pointer to some user defined data that can be
-set when creating the callback object.
-The handler itself returns a signature character (see Table \ref{sigchar}) specifying the
-data type used for \capi{result}.
