Subject: [PATCH] tree-wide: check more log message format in log_struct() and
friends
This introduce LOG_ITEM() macro that checks arbitrary formats in
log_struct().
Then, drop _printf_ attribute from log_struct_internal(), as it does not
help so much, and compiler checked only the first format string.
Hopefully, this silences false-positive warnings by Coverity.
[dtardon: Backported just the immediate fix for a compiler warning.]
(cherry picked from commit 3cf6a3a3d4acf8347ccd0250274f517e6b2e9fe6)
