[PATCH] libosmocore[master]: fix logging: out-of-bounds check should end with user catego...

[Neels Hofmeyr]

Hello Jenkins Builder,

I'd like you to reexamine a change.  Please visit

    https://gerrit.osmocom.org/1419

to look at the new patch set (#2).

fix logging: out-of-bounds check should end with user categories

To check category bounds, rather use num_cat_user, to redirect all semantically
unknown categories to DLGLOBAL.

Adjust logging_test expectations accordingly: "(d)" is now also shown.
