Prefer 'namespace which' over 'info commands', as it is faster (on local tests, around 2x) and returns a single value. Many thanks to Nathan Coulter.

- Use global variables to reduce lock contention on busy sites:

* $::acs::default_database replaces [nsv_get db_default_database .]

* $::acs::known_database_types replaces [nsv_get ad_known_database_types .]

- Cache db_driverkey per-thread (variable ::acs::db_driverkey($dbn))

to reduce high number of locks

- 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%.

- allow to upgrade basic startup files (openacs-4/tcl/*tcl)

to be upgraded via "install from repository" by adding

and after-upgrade callback to bootstrap-installer and

copying the files from there.

- move initialization of nsv_arrays for apm to -init file in acs-tcl

(as suggested by Peter Marklund, but never implemented)

- use double colon prefix rather than "global" statement

to denote global variables

- bump version number to 5.8.1d3
