* origin/topic/jsiwek/32bit-compat:
Improve formatting of doubles that are close to integers
Improve HTTP version number comparisons
Add a 32-bit task to Cirrus CI config
Replace va_list fmt() overload with vfmt()
Format tables indexed by patterns consistently across 32-bit/64-bit
Format interval values consistently across 32-bit/64-bit platforms
Using AddressSanitizer/LeakSanitizer is better. It covers the full
unit/baseline test suite by default without requiring one to write
specific memory leak tests. It also covers other types of memory errors
