Bugfix
- * Add printf function attributes to mbedtls_debug_print_msg because we were
- not actually getting any printf format specifier warnings prior to this.
- Also add extra printf compiler warning flags to builds.

+Changes
+ * Add extra printf compiler warning flags to builds.
Requirement changes
- * Use %zu for print of type size_t in new work, however please do not use
- them in backports, and preferably not in code that needs to be
- backported.
-
-
+ * The library now uses the %zu format specifier with the printf() family of
+ functions, so requires a toolchain that supports it. This change does not
+ affect the maintained LTS branches, so when contributing changes please
+ bear this in mind and do not add them to backported code.
