Whitespace cleanup

Fix doc typos

apm_source and apm_guess_db_type are called from multiple packages

improve spelling

Revert massive replacement of empty list creation sentences. The use of '[list]' instead of '{}' adds semantics that could be used for performance improvements in the future, such as using a different internal representation. There is already work in this direction, avoiding the generation of the string representation during comparison of empty strings (huge thanks to Stefan Sobernig for the pointer: https://core.tcl.tk/tcl/info/44527c632ed609c2).

We can't source the current setup files, since these perform as well the master loading of OpenACS.

Use "file tail" instead of full path for sourcing tcl file

(re)source top-level tcl-files when copying it

bootstrap installer:

- added csp policy to the files upgradeable via apm

- bumped version number to 5.9.1d5

  1. … 3 more files in changeset.
- 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

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%.
