[session] drop useless getter and setter for security Those function have very few user and does not anything fancy. Internal user now access tx.read/write_security directly. External user have been blessed with a writable property. They are only interested in the write part of they did not used the return of the removed function. They access it through the session since I prefer the external world to not be aware of Transaction yet.

[session/transaction] move read_security subtlety in transaction This is transaction data, itshould be handled by the transaction itself.

[transaction] initialize dbapi_request in __init__ There is not reason to have it implicitly declared. The attribute is renamed to match its public name.

[session] drop pre-3.7 api on session Dropping of API deprecated since 3.7 decided in #2772958

[transaction] use set operation in the hook control code We use direct operator on set instead of looping by hand, This simplify the codes.

[session/transaction] move hook management in transaction itself This is transaction level code.

[session] allow writable tx_attr and use it for commit_state This keep clarifying the code.

[session/transaction] move add operation in session code

[session/transaction] move entity life utility on transaction This access transaction related data and therefor should live in transaction.

[transaction] small simplification in ecache code A single assignation is simpler.

[session/transaction] move entity cache management on session A new utility method is added for that. It is similar to the one used for attribute access. code is copy pasted as his. Function documentation is added.

[session] have a nice helper function to forward access to session This allows a lighter and clearer code. This will also ease the addition of deprecation warning in the future.

[session] drop dead code session._tx is never None. New transaction are created if necessary.

[session] use tx.data directly in session code.

[transaction] rename transaction_data to data Transaction.transaction_data is redundant. A transaction_data property is left for backward compatibility. Deprecation mechanism will come in later changeset

[session] document Session._tx

[session] split session creation from default session assignation This is the first step for more independence for Transaction.

[session] make session lock reentrant We are going to use it for other session related business. It is renamed from _closed_lock to _lock in the same move.

[session] document set_tx

[session] rename txstore variable to tx This is a more accurate name

[session] rename `_threaddata` to `_tx` The returned object is a Transaction object.

[session] rename self.__threaddata.txdata to self.__threaddata.tx This is Transaction object now.

[session] rename _tx_data into _txs The object inside are now Transaction object. Not TransactionData object.

[transaction] relocate method building transaction context manager It is in the middle of methods going to be refactored.

[transaction] move RQLRewriter in Transaction This remove the last ``AttributeError`` magic. The ``RQLRewriter`` needs a Session. Its reset is handled in ``Session`` code to handle that

[transaction] initialize security control attribute in Transaction There is no reason to not initialize them in __init__ time. This simplify the Session code.

[session] move security constant out of the class There is no reason for it to not be global. This will ease it use by ``Transaction object``.

[transaction] initialize hook control attribute in Transaction There is no reason to not initialize them in __init__ time. this simplify the transaction code.

[session] Move hook control constants out of the class There is no reason for them to not be global. This will ease they use by Transaction object.

[transaction] initialize transaction data and state related attribute. There is not reason to not explicitly declare and initialize attribute in Transaction.__init__. This change requires the introduction of a Transaction.clear() method to get ride of some wicked ``AttributeError`` based logic.

[transaction] handle ``mode`` default value in Transaction The transaction mode is now explicitly passed at creation time and always read from the Transaction object. Note that there is a slight behavior change. The transaction mode is now set at the creation of the transaction. Changes made to the default value have no longer any effect on existing transaction.

[transaction] explicit Transaction cnxset attribute The Transaction object have a lot more attribute that those previously declared in __init__. They are just dynamically assigned in Session code. This changeset explicit the ``cnxset`` and ``mode`` attribute declaration.

[server] rename TransactionData to Transaction Transaction will become a full featured object.

[doc] update Session documentation A major refactoring of Session/Transaction handling is commit. This is a good occasion to improves the documention.
