Fix typo

Added code to skip suspicious looking query variables

On openacs.org, we are experiencing numerous requests with

multiply very long and strange query variables like in the example

below. So far, it is not clear, whether these requests are the

consequence of a double encoding or a deliberate attack. Many (most)

of the requests contain the query variable names containing the

(decoded) pattern "*amp;*".

This is a relatively new phenomenon. I cannot exclude that this is a

bug introduced lately in OpenACS, or a bug in an external bot, or

whatever. The problem with these query variables is that OpenACS

propagates these further, e.g., when updating query variables in

ad_dimensional, via export_vars, or return_urls.

Since OpenACS never uses these query-variables, these can be safely

skipped, without loosing functionality in OpenACS. It is possible to

construct examples, where skipping such variables can change the

semantics. Therefore, the change introduces a single function

util::suspicious_query_variable where in case of problems, the

skipping feature can be deactivated.

Reduce usage of ns_mktemp in OpenACS

ns_mktemp uses the deprecated old POSIX call mktemp(), which should

not be used anymore for security reasons (race between the name

creation and opening the file). This change removes several usages of

"ns_mktemp" from OpenACS and replaces it with calls to the

safe Tcl call "file tempfile ..." (introduced by Tcl 8.6).

improve robustness of output, when dot fails to produce output

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).
