Use a variable name as sizeof argument, not a type name.

Browse Source 
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).

* python/libvir.c: As above.
* qemud/event.c: Likewise.

* src/xmlrpc.c (xmlRpcValuePtr): Likewise, and minor factorization.
* src/remote_internal.c (remoteAuthMakeCredentials): Use the right
type when allocating space for an array of cred _pointers_.
