backport tracker permission utility functions into the cw.schemas package

Backed out changeset b8ea99f5e8ea, tags.a escape its content.

fix dumb name errors

fix global errors display when there is more than one error

fix error key / field input detection (field's name include -role when specified, the error key *may* include it

missing xml escapes (but textoutofcontext probably ought to be just outofcontext, with no escaping then)

3.6 api update

move autoform's field_by_name implementation on base EntityFieldsForm

specify name *and* role when raising FieldNotFound helps debugging

if specified, benefit from target_etype information in the [partial_]add_relation selector

ouch, has_perm was always returning False...

more 3.6 api update

iirk reminder

3.6 api update

has_been_modified shouldn't raise ProcessFormError

related entities are returned as tuple since a few months ago

should skip INTERNAL_FIELD_VALUE

should use a set for pending fields

fix process_form_values: we should handle value errors and properly raise ProcessFormError

refactor form error handling: * almost everything is in the base form class, with other form errors related code * deprecate form_field_error in favor of field_error and format_error on the renderer * fix pb with js localization of errors by properly using field.role_name() * rename 'errors' into 'error' in forminfo to avoid confusion

new DBG_ALL debug level

return localized message on parse_datetime errors

raising ConfigurationError is cleaner; remove some unused imports
