description refactor: change some classes to use __slots__

Speed up access to and reduce size of some low level classes. A few
classes in security.py, rest.py are heavily used. But for all, it
prevents adding random properties to lower level classes that people
shouldn't be mucking with. While doing this I found some test cases
accessing an invalid property name and this change caused the cases to
crash.

admin.py:

Use new method Role.props_dict() and Permission.props_dict() where
original code just referenced __dict__ when printing Role/Permission.

mlink_expr.py:

Add slots to multiple classes.

Classes Binary and Unary set real properties/attributes. Classes that
inherit from them (Equals, Empty, Not, Or, And) define empty slots
tuple to eliminate need for __dict__.

Class Expression also gets a slot.

rate_limit.py:

RateLimit and Gcra classes get slots.

A couple of pep8 fixes: sort imports, remove trailing spaces on a
line, remove unused noqa comment.

rest.py:

Add slots to class SimulateFieldStorageFromJson and FsValue
classes. The memory savings from this could be useful as well as
speedier access to the attributes.

security.py:

Add slots to Permission class. To prevent conflict between slot
limit_perm_to_props_only and the class variable of the same name,
rename the class variable to limit_perm_to_props_only_default.
Also define method props_dict() to allow other code to get a dict to
iterate over when checking permissions.

Add slots to class Role along with props_dict() method.

Add slots to class Security. Also have to add explicit __dict__ slot
to support test override of the hasPermission() method. Add
props_dict() method, currently unused, but added for symmetry.

support.py:

TruthDict and PrioList gets slots.

test/test_cgi.py:

Fix incorrect setting of permission property. Was setting
permissions. So testing may not have been doing what we thought it
was. Multiple places found with this typo.

Remove setting of permissions in some places where it should
have no effect on the test and looks like it was just copypasta.

test/test_xmlrpc.py

Remove setting of permissions in some places where it should
have no effect on the test and looks like it was just copypasta.

description fix: issue2551374. Error handling for filter expressions.

Errors in filter expressions are now reported. The UI needs some work
but even the current code is helpful when debugging filter
expressions.

mlink_expr:

defines/raises ExpressionError(error string template,
context=dict())

raises ExpressionError when it detects errors when popping arguments
off stack

raises ExpressionError when more than one element left on the stack
before returning

also ruff fix to group boolean expression with parens

back_anydbm.py, rdbms_common.py:

catches ExpressionError, augments context with class and
attribute being searched. raises the exception

for both link and multilink relations

client.py

catches ExpressionError returning a basic error page. The page is a
dead end. There are no links or anything for the user to move
forward. The user has to go back, possibly refresh the page (because
the submit button may be disalbled) re-enter the query and try
again.

This needs to be improved.

test_liveserver.py

test the error page generated by client.py

db_test_base

unit tests for filter with too few arguments, too many arguments,
check all repr and str formats.

description flake8 fixes - exception handling changed

flake was flagging the bare except: expression. From testing, it
looks like that exception handler only gets ValueError. So changed it
to

except ValueError:

and added an

except BaseExpression

that just re-raises the exception. But I think this better expresses
the expected flow.
