838596c7a4 Implement countSubstrings() 
Function to count number of substring occurrences in the string:
- in case of needle is multi char - counts non-intersecting substrings
- the code is based on position helpers.

The following new functions is available:
- countSubstrings()
- countSubstringsCaseInsensitive()
- countSubstringsCaseInsensitiveUTF8()

v0: substringCount()

v2:
- add substringCountCaseInsensitiveUTF8
- improve tests
- fix coding style issues
- fix multichar needle

v3: rename to countSubstrings (by analogy with countEqual())
