c57a86ce62 src: Fix undefined behaviour 
Cppcheck produces the following warnings:

```
shared_string.hh:27:49: portability: Shifting signed 32-bit value by 31 bits is implementation-defined behaviour
shared_string.hh:27:49: error: Signed integer overflow for expression '1<<31'.
```

Fixes #4340

d9abc2a156 Refactor StringData and StringRegistry to remove need for purging 
Purging unused strings could get pretty expensive with a lot of
interned strings as it requiered iterating on all of them. Use
a flag on the refcount of the StringData to see if the string
is interned, and notify the StringRegistry in this case.

This should improve the speed of editing big files with many words,
such as the one described in #1195

072064407a Remove hash from StringData 
Maintaining the hash value of strings is not worth it as we only
use it for buffer reload, but pay for it on any buffer modifications.
