Add nstime_ms_since to get time since in ms

Browse source 
Milliseconds are used a lot in hpa, so it is convenient to have
`nstime_ms_since` function instead of dividing to `MILLION` constantly.

For consistency renamed `nstime_msec` to `nstime_ms` as `ms` abbreviation
is used much more commonly across codebase than `msec`.

```
$ grep -Rn '_msec' include src | wc -l
2

$ grep -RPn '_ms( |,|:)' include src | wc -l
72
```

Function `nstime_msec` wasn't used anywhere in the code yet.
