backport of afef71d6b9
Original commit message:
Let `create` and `write` round monetary field values before sending them to the
database. Pass the values to be written to `field.convert_to_column`, so that
the currency can be retrieved from the values, and the value be rounded.
When doing a group_by in a tree view, and then ordering by an
aggregated field which contains at least one capital letter in its name,
you will get an error and won't be able to ordery by this field.
Why? read_group is called when sorting a group by, which calls
_read_group_raw which then goes to call _read_group_prepare, which will
return order by terms in this manner ['id asc', 'x_Test desc']
the problem with this is that postgres automatically converts
non-quoted/non-qualified column name to lowercase, of course this means
that if we have a field "x_Test" but no field "x_test", it will try to
look up "x_test" instead of "x_Test" and since the column doesn't exist,
it will throw a ProgrammingError.
This commit changes this behavior by wrapping the order_by terms generated in
_read_group_prepare with double quotes, which postgres interprets
correctly.
Fixes#21348
Cherry-Pick of c338e24ee7 as previous
forward-port has been badly done...
Remove weird special case: when the first field of the first line of a one2many
is empty, replace this first field by the comma-separated names of the lines,
and discard the other lines.

Otherwise if a record rule is defined on a x2many field on the model, the creation will fail because
ir.translation creation check access rules on the model and in this case, the x2many relation are
not set yet.
The command does not need to remove existing relations, as there is no relation
yet on new records. This saves one query per many2many field with that command
in a `create`.
Make `RecordCache` work on a single record only, and implement a mapping from
field names (only) to values.
Also add explicit methods on `RecordCache` to wrap special behavior in cache,
and simplify all special values as a wrapper for a getter function.
The record cache may contain regular and special values. Modify `RecordCache`
so that only methods ending with `_value` check for regular values. The
dictionary methods considers both regular and special values as equivalent.
name in record._cache # test if cache has a value
iter(record._cache) # iterate on values
record._cache[name] # get value
record._cache.get(name) # get value or default
record._cache.has_value(name) # test if cache has a regular value
record._cache.get_value(name) # get regular value or default
The x2many "create" command is now like: `(0, ref, vals)`, where `ref` is an
arbitrary reference that may be used to identify a new line in the relation.
The reference is returned in a similar command by the method `onchange`.
`onchange` now supports self-modifying x2many fields.
The behavior is no longer implemented by the web client. Implement it
server-side as part of the onchange mechanism, simply by defining onchange
methods for the fields that have the flag.
Now that we're closer to switching to P3 for good, these helpers have
outlived their usefulness, and mostly add noise.
All remaining dict.iter*() or dict.view*() must be converted to the
normal keys(), values() or items() calls.
Whenever the result is likely to be used for more than the scope of a
loop, or when the dict needs to be modified during iteration, the calls
must be wrapped in a ``list()``, to protect the new P3 semantics.
Those cases are very exceptional.
Also removed some dead code or improved the API to remove unnecessary
conversions.
* remove references to basestring & unicode (use relevant pycompat
helpers)
* remove some str calls (either entirely or replaced by relevant
helper, either text or native)
* use better API to avoid unnecessary conversions
* remove some XML declarations in views
