39896cb955 Fixed CORE-1671: atexit() calls in client libraries cause segfaults 
and CORE-1079: Every attach of fbclient/fbembed library leaks 64KB of memory

To do it:
- created new template GlobalPtr, controlling access to destructors of global objects.
- applied it to global objects.

Also some related cleanup.

Original behaviour caused errors with updatable views or procedures receiving BLOB arguments.

710037031f Enhanced Index Structure. 
1) NULLs on top when sorting on ASC index, DESC stays the same.
2) Support for larger index lengths, can be up to 1/4 page size.
3) Store record-number on non-leafpages for faster lookup in many duplicates.
4) Jump-nodes for faster key-lookup in index on larger page-sizes.
5) Segment selectivity calculation added.
