[Devel] unified pseudo-variables in avpops and xlog

[Miguel Angel Villar]

Hi Daniel
	This is a really nice feature. I had been looking for something like
this in the textops module. Implementing pseudo-variables in subst_uri() and
subst() functions will give power tools for doing dynamic number/domain
translation of URI. Conbined with avpops module the transformation can be
based on external database, Great!

Regards.
