[IMP] various: improve code style and performance by improve ``all()`` usage

PURPOSE

Clean code. Be more performance oriented.

SPECIFICATIONS

Improvements applied in this commit

  * not all() --> any(not) for earlier returns;
  * all([generator]) --> all(generator) to avoid unnecessary list casting.
    This code construct is better managed by all;

This commit will probably not have a big performance effect on standard
production databases. However each performance and cleaning improvement
is welcomed.
