Base.edit has this feature of not actually modifying the properties when
the new property value is same as the current one, so when we do
`movement.edit(price=x)`, this will cause an implicit getPrice.

As price lookup is a bit slow, do not lookup price in this case.

Fix for [#20160719-1B69F57]( https://nexedi.erp5.net/bug_module/20160719-1B69F57 ) 

These after clone methods in transformed resources are being too clever and behave very badly when the transformation itself is cloned.

The suggested approach is to stop initializing int index & reference when cloning transformed resources ("transformation lines"). This behavior is kept when adding new transformed resource. This become consistent with what we have, for example, with Sale Order Lines in Sale Orders.

In the same time, stop showing range of cores like "9 to 15" cores. The infrastructure should be
important enough to have all the time the maximum of cores in the range. So just use the maximum
in the range, "15 cores" here.

Make sure we find section if we render https://my_site/my_section/foo.html. This is required
to take into account configuration of the web section, like specific content security policy.

Should make test output more expressive on failure.

To make it more likely detect killed transactions before entering
tpc_finish phase.

Saves one round-trip to server.

This parameter does not force a reconnection, it allows reconnecting if
a closed-connection is detected when querying on a transactional
connection on which the transaction was already started.

Otherwise, all subsequent tests fail too.

This reverts commit 699759bc

Do not give conflicting instructions to portal_catalog.

Preserve compatibility with in-zodb worklist cache code, but do not use
*_expression when calling catalog.

These are a bit more complex, there are more to come.

These are the easy uses, there are more to come.

Waiting document onlyoffice conversion error fix

In order to safely use non-XML allowed characters coming from various
sources wrap basestring into xmlrpclib.Binary before sending it to the
server.
