formalize log subsys stripping for vty
In osmocom, we historically have a leading 'D' in all of our logging
subsystem names -- not only in the enum entry name, but also as the
string in struct log_info_cat[].
As a result of this, our logging_vty code strips away the first
character of each logging subsystem name. In the VTY, we don't enter
'dmain', but only 'main' -- the VTY strips the 'D' from "DMAIN".
The intention is to make this stripping behavior optional in a
subsequent patch.
So far the code to do that is a magic "+ 1" thrown in here and there.
Instead, introduce log_subsys_name() and use it where ever logging_vty.c
does removal of the leading 'D'.
I would have liked to keep this within logging_vty.c, but unfortunately
it needs to be public API in logging.h, because of log_parse_category()
which also strips leading D and lives in logging.c.
