Add a requirements of a page to the CSP in order to generate

later a tailored policy with the minimal permissions for

this page. For example, the following requirement is

currently added per default to the oacs-master template to

permit style tags and style attribites in the markup.

security::csp::require style-src 'unsafe-inline'

security::csp::render:

Generate a policy from the requirements

* Added Kernel Parameter CSPEnabledP to activate/desctivate CSP

*** empty log message ***

- avoid cyclical dependency

- Improve robustness of blank-master: malformed lists in subsite

parameters could render a subsite useless and hard to correct.

Now the validity of lists is checked, errors are written to the

error.log, invalid parameters are ignored.

- added flat list syntax for ThemeCSS specs (easier to read)

- added parameter ThemeJS similar to ThemeCSS (ability to add head and

body scripts)

- added generalized function template::add_script with non-pos

parameter "-section" which might be "head" or "body" to make both

kind of scripts available to ThemeJS

- optional performance boost for site-nodes:

the site-node code contains an optional performance booster,

that speeds up site-node operations froma factor of 2 to

several thousand times. The performance boost ist just

available for the time being for PostgreSQL, XOTcl2 and

NaviServer and is only activated, when these componentes

are available.

- bump version numbers

ad_proc reform:

- use nsf::proc for defining ad_procs, when nsf::proc is available

- nsf::proc is part of the environment of XOTcl2 and provides

an efficient, C-implemented argument parser that can replace

the scripted *__arg_parser of OpenACS.

- The benefits are performance and reduced memory consumption.

* Simple functions (where the calling overhead was a large

part of the execution times can become several times faster

(e.g. db_name is 3x faster, cookie handling is 2x faster),

for functions with much db-activities the percentage will

be less.

* The memory consumption (RSS) of a site like OpenACS.org

is reduced by about 15%.
