new function: ad_unless_script_abort and bump version to 5.10.1b12

This convenience function eases handling of ad_script_abort exceptions

in cases, where the OpenACS request processor is not involved.

From the documentation:

Execute the provided body in the callers' environment. When the

body does not raise an "ad_script_abort" exception, the

"non_abort_action" is also executed. This pattern is useful when

handling client requests and where the "non_abort_action" is used

to return results to the client. When "ad_script_abort" is

executed, the connection is usually closed, and any attempt to

talk to the client over the closed connection will fail.

The handling of script_abort exceptions is done usually in the

request processor. The function is useful when registering own

request procs (e.g., via "ns_register_proc") where the OpenACS

request processor is not involved.

bumped version to 5.10.1b12

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.

Exception handling reform (part 1)

- implement ad_try based on (byte-compiled) Tcl try to make exception

handling more Tcl compliant

- Replace several "catch" operations in request-processor by ad_try

- de-spaghetti "rp_handler" and factor out "rp_handle_request"

- Provide error context in log message in a more uniform way

- handle ds stub-procs in a more uniform way:

provide as well a stub for "ds_init" instead of

wrapping it into a "catch" operation.

- move deprecated procs "ad_return" and "rp_handle_adp_request"

from request-processor-procs to deprecated-utilities-procs.tcl

- bump version number of acs-tcl to 5.10.0d2
