Restored (intentional) content of screwed up commits 1bcdf4ce3d and 674f7980d519712ff16d8f874dfe55a84deb4b5b:
...
- New check (Inconclusive): Array filled incompletely with memset/memcpy/memmove
-- This check only warns if the number of elements is given as size in bytes to memset, memcpy or memmove and if the size of an element is larger than 1 Byte. It does not warn for random numbers
- New check: Detect ineffective statements like '*foo++;' (Should be: '(*foo)++;')
Sorry for the inconveniences.
