How the scripts are called

Normally the scripts are called by xl (and thence libxenlight?) because they are named in /etc/xen/<DomU name>.cfg.

Structure of the scripts

The scripts are written in bash.

The scripts use a lot of common components: bash scripts which are sourced mostly to define functions.  For example, here is the start of the vif-bridge call tree.
