Purpose
=======

Calling copy in a list comprehension or a loop does break the batch definition of many stuffs (create, message_subscribe, followers management, ...) leading to a large amount of unnecessary requests while duplicating many records.

The copy method is actually the only method left from the old API that does not handle recordsets.

This commit is making the copy and copy_data methods work in batch improving the execution of the computed fields, and the whole records creation process.

Now, copy works mainly like this:

@api.returns('self')
def copy(self, default=None):
    vals_list = self.copy_data(default)  # this one returns a list of vals
    return self.create(vals_list)

And if you want specific vals for each record in the output, simply use copy_data() and modify its output accordingly, like in:

@api.returns('self')
def copy_data(self, default):
    vals_list = super().copy_data(default)
    return [dict(vals, name=_("%s (copy)", product.name)) for product, vals in zip(self, vals_list)]

For the record, duplicating 400 project.tasks (with lot of postprocess on copy about milestones, task dependencies, SOL mapping) divides the number of sql request by 2.4 (11000 -> 4500) and divides the execution time by 3 (15 -> 5 seconds).

TaskID: 3742289

With this commit, list data is loaded using `web_search_read` instead of `search_read`.

The goal is to fetch the currency (symbol, decimal places, etc.) of monetary fields in a single request, instead of 2 RPCs.

Pros:
- less code
- one evaluation saved
- one network request saved
- easier future refactoring (see below)

Cons:
- overhead of data transferred over network (from 4.5MB to 6.5MB, unzipped, to fetch a list of 20K crm leads).

Before this commit, here is what it looked like:

1. the list data is fetch (with the currency_field)
2. the cells are evaluated with the new data
3. we realize we want to format a currency amount. We already have the currency name but not the symbol, etc. So we fetch the currency data
4. evaluate the cells again with the new currency format

Now:
1. fetch the list data with everything we need for the currency
2. evaluate the cells

This commit also serves another goal for a future refactoring: in the hope of avoiding throwing "loading errors", I'd like to have an easy way to know if a data source is fully loaded or not (the data and the format). With this commit, everything is centralized in the list data source with a single RPC. The goal is therefore achieved with this commit.
