Add _c versions of functions that otherwise return static buffers
We have a habit of returning static buffers from some functions,
particularly when generating some kind of string values. This is
convenient in terms of memory management, but it comes at the expense
of not being thread-safe, and not allowing for two calls of the
related function within one printf() statement.
Let's introduce _c suffix versions of those functions where the
caller passes in a talloc context from which the output buffer shall
be allocated.
