base: utils: Add and use strtod() helper
The strtod() function is locale-dependent, and thus ill-suited to parse
numbers coming from, for instance, YAML files. The YamlObject class uses
strtod_l() to fix that issue, but that function is not available with
all libc implementations. Correctly handling this problem is becoming
out of scope for the YamlObject class.
As a first step, add a strtod() helper function in the utils namespace
that copies the implementation from YamlObject, and use it in
YamlObject. The core issue will then be fixed in utils::strtod().
