This is a fixup of 665166e2 (see
especially nexedi/slapos@665166e2 (comment 177402))

see https://chromium.googlesource.com/chromium/tools/depot_tools.git#updating

as a result, this checkout was not pinned and software was not
reproducible

also make sure component/slapos/buildout.cfg is installable in Theia:
 * we can't compile old gobject-introspection with Python3.9
 * we can't patch dbus as it is read only

See merge request nexedi/slapos!1299

See merge request nexedi/slapos!1333

no need to have an exception here, long time ago bytes had an insecure
default, but we changed to make the default secure

We need to fix the rpath to pass the software release test.

For xproto, xextproto and renderproto

When user ran out of inotify watch, starting wrappers using
wait-for-files is not possible:

    AssertionError: Traceback (most recent call last):

This catches inotify errors and fallback to simple polling in that case.

Running logrotate -d on cluster with a lot of slaves results with execution
taking a lot of time (>10s, one some nodes ~20s), which leads to random
promise timeouts.

instance-slave-list.cfg.in is run by instance-frontend.cfg.in, which
implements that exact promise already.

Default software_type requests all required instances for the swarm.
