[PATCH v2 08/21] gdbstub: move fromhex/tohex routines to internals


From: Alex Bennée
Subject: [PATCH v2 08/21] gdbstub: move fromhex/tohex routines to internals
Date: Thu, 5 Jan 2023 16:43:07 +0000

These will be needed from multiple places in the code. They are
declared as inline so move to the header and fix up to modern coding
style.

The only other place that messes with hex stuff at the moment is the
URI handling in utils but that would be more code churn so leave for
now.
