[PATCH 5/5] miinitext: introduce LoadExtensionList() to replace over LoadExtension()
Emil Velikov

Looping around LoadExtension() meant that ExtensionModuleList was reallocated
on every extension. Using LoadExtensionList() we pass an array thus the
function can do the reallocation in one go, and then loop and setup the
ExtensionModuleList.
