* text2latex.py: call main() instead of always processing ext.tex.

* Makefile: added 'ext' to 'all' target
* ext.tex: more changes towards a readable text
* lib4.tex (posix): added set{uid,gid}
* lib2.tex (array): restored doc for typecode and itemsize (which were
  there but not visible for dir())
