build and debug on current MacOS, test DSN will now also apply parameters

[1R053]

• some build settings were updated to build and install on current MacOS and XCode
• also debugging is now possible with a development build, e.g. using CLION and attach to process will stop at breakpoints (except in macros)
• bugfix: test DSN now will also apply datasource parameters
• bugfix: loginDialog crash memory leak fixed
• bugfix: SQLDriverConnect without any DSN specified will now also apply DSN parameters after the DSN chooser dialog
• iodbctest enhancements:
  • universal binary
  • if driver does not support SQL_DRIVER_COMPLETE it calls the driver with the connection string defined in the DSN
  • added a "sleep" command to allow attaching a debugger (otherwise the program stops when a debugger attaches while waiting for user input)

Thank you for your contribution. We will do a review of this request shortly.

@1R053 — My reviews have least importance here, as my primary coding language is English. @pkleef and @smalinin manage the compilation source code.

once you compile it for deployment I'd be curious, if the driver access issues are resolved. With the current version of iODBC drivers have to be installed in a specific directory on MacOs in order to avoid access errors. I don't have that anymore with my local builds (production and development) but I am not sure if that remains in a deployment build.

For example I can now without problem use the SQLite homebrew drivers or other drivers like Snowflake from their install location instead of having to move them manually into an allowed folder.
