This now supports producing html reports directly

nbd2-host and nbd2-port are asserted too.

Test are reorganized to easily assert mixed scenarios.

Zope no longer serve XML-RPC in ERP5, unless it is explicitly enabled
using this.

--enable-readline is broken:
  - it searches for readline.h instead of readline/readline.h
  - it does not abort when it fails to find headers
Use --with-readline-inc so that it sets HAVE_READLINE.

Also use the dedicated configure option to enable update limit.
And sqlite3 does not depend directly on ncurses.

Similarly to wendelin.core (see ad34ff4a "wendelin.core: Always use git
checkout for both release and development version") let's switch pygolang to
install via git checkout for both release and tests.

This way we avoid dependency on pypi and will be able to do minor updates
without doing bigger to-pypi releases. Always using git checkout also helps
security a bit because we remove reliance on trust to tarball received from pypi.
