IPP options with ‘-‘ in the name ignored, when passed to ipptransform

[AFischer4]

Calling ipptool -v -T 3 ipp://<IPPHost>:8000/ipp/print/<MyPrinter> -f <sample>.pdf ex-print-job.test
fails to propagate IPP options with ‘-‘ in the name to ipptransform.

For example ATTR enum print-quality 5 in ex-print-job.test will be passed to ipptransform as environment variable IPP_PRINT_QUALITY=high but the function get_option() in ipptransform does not find the option, because it is looking first for a non existing command line option “print-quality” then for an environment variable “IPP_PRINT-QUALITY” and then for “IPP_PRINT-QUALITY_DEFAULT”.

The algorithm in get_option() to build the name of the environment variable must be the same, as in serverTransformJob().
At the moment the replacement of ‘-‘ to ‘_’ is missing in get_options()!

Without correction, ipptransform will ignore a lot of options set by environment variables, because the initialization in ippOptionsNew() / get_option() is looking for the wrong names.

I used ippsample "v2023.03" for the tests.
