device: Add API for perstistent data storage

store it to disk. It is undefined when this data is updated by the
driver, but in general, it should only be updated once the first time
a device is used.

+Subject: [PATCH] nbis: fix build on musl
+
+Drop re-definition of stderr. There's no need for this anywhere
+(including glibc). This breaks in particular on musl because
+stderr (and stdin) are both const, and macros unlike in glibc.
