New xgettext method for i18n module

This method call xgettext to extract translatable
string from source files into a .pot translation template.

It differs from a plain CustomTarget in three ways:
- It accepts build targets as sources, and automatically resolves source
  files from those build targets;
- It detects command lines that are too long, and writes, at config
  time, the list of source files into a text file to be consumed by the
  xgettext command;
- It detects dependencies between pot extraction targets, based on the
  dependencies between source targets.
