Until now it was disabled which means that if Component A imports Component B
and the latter is not in {validated,modified} state, Component A could be
validated without raising any error and failed at execution time.

As this relies on Pylint transform/hook and avoiding monkey patch as much
as possible, make Products.ERP5Type.patches.pylint available for Python3 (not
actually tested with ERP5 but no AttributeError nor ImportError with Python3
with this code).

Also, allow developer to call validate action from 'modified' state to handle
import use case:
  1. Edit A which raises an error stating that B.
  2. Fix B and validate it.
  3. Validate again A without requiring a modification of {reference,version,text_content}.

ZODB Components: Source code was checked even when setting text_content_{error,warning}_message_list properties.

So only check source code and validate when _set{TextContent,Reference,Version}
are called and remove wildcards.

Sometimes validator.erp5.net replies with error code 502 and this cause
ERP5 tests to fail. While this is a bit like ignoring problems, problems
with validator.erp5.net should not impact ERP5 tests results.

Conversion Server code is no longer bound to OOo, as emphasized by:
  * Renaming of Preference Properties ooodoc_server* to document_conversion_server*.
  * Conversion Server exceptions are already defined in Document.py.
  * Conversion Server also handles video/audio/... conversions.

Thus, refactor the code to connect to Conversion Server by moving it from
Products.ERP5OOo.Document to Products.ERP5.Document.Document (while keeping
backward compatibility):
  * Renamed:
    + OOoServerProxy => DocumentConversionServerProxy
    + OOO_SERVER_PROXY_TIMEOUT => DOCUMENT_CONVERSION_SERVER_PROXY_TIMEOUT
    + OOO_SERVER_RETRY => DOCUMENT_CONVERSION_SERVER_RETRY
  * Moved:
    + enc
    + dec
    + global_server_proxy_uri_failure_time

Also, Introduced erp5.module.TransformLib (in erp5_core as currently all Transforms
are there even though it should probably not be so) to define DocumentConversionServerTransform
and which will hold libtransforms content when this will be moved to ZODB Components.

Note: Ideally, OOOdCommandTransform should inherit from DocumentConversionServerTransform
but wkhtmltopdf Handler on Cloudooo side is a hack only implemented in Manager.convertFile()
whereas OOOdCommandTransform still uses legacy Manager.run_generate(), so leave it as it is
to avoid breaking things (this will be addressed in a separate MR).

ZODB Components: Add 'Origin' (source_reference) field showing from which FS module it was imported.

* pylint may return a false positive error which have to be disabled and
  failing to import it because of that requires to edit on the FS and try
  again so it is not practical for a whole Product. Instead it is easier
  to import it and not validate
* Validation was done only for 'Test Component' and 'Extension Component',
  but all imported Components had their consistency and source code checked
  and this is not consistent to not validate but do these checks.
* importFromFilesystem() was checking consistency and source code, and this
  was done again when validating.

So leave the imported ZODB Components as draft and let the developer fixes
issues upon validation before committing.

ZODB Components: List of migratable 'Module Components' in Products.XXX.* should include any kind of objects and not only modules.

This fixes Products.ERP5VCS.Git module not being displayed because
Products.ERP5VCS.__init__ only imports one of its class and not the whole
module (and the module was not imported anywhere else too) so it was not in
Products.ERP5VCS.__dict__.

useStdin=False => temporary file was not created.
useStdin=True  => temporary file was created.

ZODB Components: Monkey patch pylint to avoid 'No config file found, using default configuration' on stderr.

Another solution could have been to have a configuration file for pylint instead
of command line arguments but it depends on the type of Component (for example
'Interface Component' has specific arguments).

After upgrading bt5s, portal_sms may still ERP5BaseBroken until restarting Zope.

ZODB Components: Allow migration of {Interface,Mixin,Module,Tool} from Business Template UI and on all Products (not only Products.ERP5).

This introduces the following new ZODB Components:
  + Module Component: Non-Documents/non-persistent classes of modules usually
    found at the top-level of Products (eg Products.ERP5.XXX) on FS. Considering
    that all other Components types are actually Modules, make it the base class.
  + Tool Component: Tool directory of Products on FS (eg Products.ERP5.Tool.XXX).
    => DiffTool and CallableTool are now 'Tool Component' instead of plain
       'Document Component' and properly registered as Tools like FS Products Tool.

Skip CMFActivity and HBTreeFolder2 Products for now in migration View for now as
almost many Portal Type classes have ActiveObject or HBTreeFolder2 in their MRO
and these Products will be done at the end anyway...

This often divides the size by ~3,
and also memory usage if it is loaded again.

* Add erp5_core_proxy_field_legacy to dependencies (because of (at least) my_password).
* Rename ERP5ShortMessage.Errors module because the name is too generic for a 'Module Component'.
* Fix type_class of SMSTool: This should be the name of the class only, excluding the module.
* Add missing __init__.py to tests directory so that it can be migrated.

This is done by inheriting most of the code of ConflictFreeLog,
i.e. using a doubly-linked list:
- for fast iteration of the first elements, and in particular
  immediate access to the first element (used for creation date);
- that keeps track of the history length;
- that implement fast reverse iteration (although it could
  have been done without changing the data structure).

The size of buckets is not fixed anymore to 16 items:
like ConflictFreeLog, WorkflowHistoryList is also a good candidate
to look at the estimated serialized size of the bucket in order to
decide if elements should be added to a new one or not.
Then developers won't have to care about using Pdata or not.

The size is bigger than the ConflictFreeLog default,
because workflow items look a lot alike and adding
a few more is cheap when the ZODB compresses.

No more optimized __getstate__ (except for workflow histories that
have not been migrated) so BT export will be a bit more verbose.

The BBB code is because of

ZODB Components: Before migrating Interfaces from FS, there must be one Interface class per source file matching its name.

Same as Document class: this avoids registering Interfaces at startup and just do it
when using the Interface. In assuming that portal_components/XXX has a class
name equals to XXX.getRference(), it is easier to:
 * List all existing Interfaces (for example in Portal Type Class view): getReference()
   on all validated 'Interface Component' in portal_components.
 * Lookup for an 'Interface Component': 'from erp5.component.interfaces.XXX import XXX'.

ZODB Components: Properly handle addition of template_* properties in BusinessTemplate PropertySheet.

On the plus side, this avoids an ugly 'except AttributeError: pass' which does
not work anyway with the scenario below.

Assuming the following:
  * template_XXX Property (accessor: getTemplateXXX) recently added to BusinessTemplate PropertySheet.
  * erp5_YYY sets template_A Property (erp5_YYY/bt/template_XXX.xml).
  This commit handles the following:
    1. Stop instance with old ERP5 without template_XXX.
    2. Update erp5.git.
    3. Start instance.
    4. Upgrade erp5_property_sheets and erp5_YYY bt5s in *one* transaction from portal_templates UI.
    => When upgrading erp5_YYY, BusinessTemplate.importFile() imports erp5_YYY/bt/*.xml where the
       list of files is based on BusinessTemplate class propertyMap(), but at this point accessors
       have not been re-generated yet, thus template_XXX is not returned by propertyMap() and
       erp5_YYY/bt/template_XXX.xml is not imported.
       => portal_templates/erp5_YYY new BT does not have template_XXX property set at all.

This is the case with runUnitTest wrapper created by SlapOS but is not actually required
as manage_addERP5Site has 'test test' as default value.

This fixes:
  File "custom_zodb.py", line 70, in <module>
    sql_db = Products.ZMySQLDA.db.DB(os.environ['erp5_sql_connection_string'])
  File "UserDict.py", line 40, in __getitem__
    raise KeyError(key)
KeyError: 'erp5_sql_connection_string'

Exactly like prices and other properties, it is useful for some projects to define different
descriptions depending if we are doing sales or purchases

[erp5_core] Return 400 status code when updating a dialog

Assuming that the test database already exists and 'movement' table already
contains data (from past execution for example), on '--save' before this
commit:
  1. Create a new ERP5 Site:
     1. Install erp5_mysql_innodb_catalog.
     2. Call ERP5Site_reindexAll(clear_catalog=True) (from ERP5Generator.setupIndex()).
        => At this point, erp5_mysql_innodb_catalog tables are recreated.
  2. Install erp5_movement_table_catalog or any bt5 adding a new SQL table.
     => This does not recreate the table and leave the existing data as it is.
  3. Dump MySQL database to dump.sql.
  => dump.sql contains 'INSERT INTO' for 'movement' table *before* this '--save'.

This fixes random customer Unit Tests failures on SQL queries accessing
'movement' table directly and getting {non-existing,past executions}
Movements.

Before the change testing the value set for category membership,
"p1.setCareerSubordination(o1)" was not raising, making this test
useless in reality. With the change, this now raises, but with a
different message.

Our patched MySQLDA assumes that DATE and DATETIME columns are in UTC,
but the TIMESTAMP columns are using mysql's time_zone variable, which
defaults to mysql server system timezone.

Set time_zone session variable at the beginning of each connection so
that TIMESTAMP columns are also UTC.

This API is not supposed to take into account security,
unrestrictedSearchResults is usually a bit faster

Before this change, class hierarchy is like this when using mixin:
```
class MyClass(BaseClass, Mixin1....)
```
which is usually ok when classes don't override each other's

But if we want to overwrite BaseClass's method by using mixin to do more thing,

For example:
```
class BaseClass(object):
  def test(self):
    print 'base test'

class Mixin1(object):
  def test(self):
    super(Mixin,self).test()
    print 'mixin'
```
I want to display 'mixin base test' when call test, but it doesn't work

since priority of how methods are resolved is from left

to right: BaseClass----->Mixin1, it only display 'base test'

So the correct way to use mixin should be in reverse order:
```
class MyClass(Mixin1, BaseClass)
```
