Added CMS_API.request: WSF_REQUEST to ease dev of ROC CMS code.

- Removed CMS_REQUEST_UTIL
  - centralize a few request related code into CMS_API
Added CMS_API.user, CMS_API.set_user (CMS_USER), ... and user related routines.

Refactored Auth related code
  - added various abstractions to factorize implementation and harmonize solutions.
  - revisited the logout strategy.
  - updated the account info page, and remove info user should not care about.
  - simplified the process, and encourage auth module to follow same design.

Added CMS_LINK helper routines to modify the related query string.
Removed CMS_USER.profile (and related routines)
   - It was not used so far.
   - it will probably a specific module later, if needed.

Update various module to avoid fetching user from sql directly, and let this task to CMS_USER_API.

Removed CMS_NODE_API.node_author (a_node: CMS_NODE): detachable CMS_USER,
   - as the info is already in CMS_NODE.author

Added CMS_RESPONSE.redirection_delay, if ever one code want to redirect after a few seconds.
Added the request uri info to the not found cms response.
