4a67038e56 * Added a new function hash_insert_grow() that grows the hash table when needed. 
* Removed the public hash_grow() function again (at least for now, it's only
  private).
* Removed the newSize argument from hash_grow(); it will compute the new size
  automatically.
* The block cache is now using hash_insert_grow() instead of hash_insert()
  which should make hash lookups much faster with some 10 thousand blocks,
  also increased the initial table size from 32 to 1024...

dfa4dfe033 Something else that has been laying around for some time. Implemented hash_grow() that can grow a hash table to a new table size. Automatic growing is commented out in hash_insert() since there needs to be a way to disallow growing in certain cases (i.e. where no allocations can be made). This is detailed in the ToDo at the top of the file.

40c3aedf8d * Added hash_count_elements() and hash_count_used_slots() (mainly for 
diagnostic purposes).
* hash_init() adjusts the table size to a prime number, which should
  result in a better element distribution, particularly since usually a
  power of two is passed.

826e857cf0 Implemented hash_remove_current() which removes the current iterator position 
from the hash - not yet tested.

52fe8bf7a8 Minor header cleanup: moved some headers to better matching directories, 
removed unused headers. Adapted sources to still compile with the new
header locations.
