make sure not to release handles active in an transaction, transactions are based on handles

activate usage of "ns_db currenthandles" when available

add error, when we are running out of handles

reduce verbosity, deactivate usage 'ns_db currenthandles' for now

fix typo

db_handle reform

Use "ns_db currenthandles" (when available) to implement "db_with_handle"

instead of the old approach based on the global db_state variables.

The enws approach has the advantantge that it is

- more robust (deletion and creation of the per-request variables,

no coherency problem),

- simpler, and

- faster (less overhead per db_with_handle call, simple queries up to 20% faster)

time {db_string . {select object_id from acs_objects limit 1}} 1000

old: 200-230 microseconds per iteration

new: 160-180 microseconds per iteration

Reduce code duplication (passes automated tests)

improve spelling

  1. … 15 more files in changeset.
Whitespace cleanup

Remove proc doc duplication in 'db_1row'. As the proc is essentially a wrapper for 'db_0or1row', just a pointer is better, avoiding future issues if parameters change.

prefer built-in ns_dbquotevalue over DoubleApos

fix typo

Port from downstream cache transaction logics and fix automated test as now db_transaction will return 0 instead of the empty string (and no particular return value should be assumed)

reduce hammering on nsv for variables that never change. Use namespaced variables instead.

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).
