common: add json_add_timerel helper.
What the developer wrote
Authored by Rusty Russell
common: add json_add_timerel helper.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
What changed, and why it matters
This commit simply adds a new helper function for formatting relative time values as JSON numbers. It is a routine, non-security code addition with no bug fix or behavior change to existing features.
No security action needed. Review as normal code-quality change if included in a larger feature.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The patch introduces json_add_timerel() in common/json_stream.c/h, mirroring the existing json_add_timeabs() helper. It formats a struct timerel as seconds.nanoseconds using the same json_add_primitive_fmt mechanism. No callers are added, no existing logic is modified, and no security-sensitive operations are involved.
