Karel Kočí b851916d76 libs/libc/obstack: fix allocated chunk overrun due to invalid limit 
This primarily fixes allocated memory overrun due to invalidly
calculated limit of the chunk. The function here allocates chunk of size
that includes required header. The error was that size of the chunk was
invalidly again added when limit was being calculated. This was causing
memory overrun and issues especially with object growing (reallocation).

The secondary fix here is to the algorithm that rounds the required size
to the multiple of chunk size. In short chunk size must be reduced by
one to get the correct mask. The condition that was generating the mask
was also invalid because it must perform shift with at most one less
than number of bits (not bytes).
