Given code like: T *var = calloc (n, sizeof (T));
Convert to this: T *var = calloc (n, sizeof (*var));
This first-cut change adjusts all malloc, calloc, and
realloc statements.

The only binary differences are in remote_internal.c
(due to the bug fix) and in xmlrpc.c (due to factorization).

  remoteDispatchAuthPolkit, the no-op init call when policykit

        Change #include <> to #include "" for local includes.
        Removed many includes from src/internal.h and put them in
        the C files which actually use them.
        Removed <ansidecl.h> - unused.
        Added a comment around __func__.
        Removed a clashing redefinition of VERSION symbol.
        All limits (PATH_MAX etc) now done in src/internal.h, so we
        don't need to include those headers in other files.
