bfs: Use the QueryParserUtils instead of its own copy.

* Ingo copied the methods into a shared location, and then obviously
"forgot" to let BFS use them. As a side note for Ingo: the complete
error GCC reported was "std::fssh_size_t" not defined with the macro
wrapper as code location. The actual problem was a "using std::size_t"
in some C++ header that accidentally got included after the wrapper.
* The shared Query code is not yet used. That'll be done another time.
* Renamed BFS_SHELL define to FS_SHELL, such that QueryParserUtils can be
used in any file system shell, not just the bfs_shell.

Implemented repairing index b+trees.

* There are now two passes in case a corrupted index tree has been found.
* The second pass will clear the affected indices at first, and will then walk
over all inodes again to fill them.
* As a side effect, this will also defragment the indices; ie. the same
mechanism could be used for this some day.

When running checkfs, BPlusTree::Validate() is now called.

* Let checkfs collect stats of how the data streams are used.
* Would be nice to only show this when an extra argument had been passed to
checkfs, but I'm afraid the API is somewhat limited, not to say pretty much
unusable for the task.

* checkfs is now working again; I couldn't test my earlier changes because I had
no time left, but I didn't want to lose them either.
* This fixes bug #5536, sorry for the inconvenience.

* Removed the cookie field of the check_control structure; that really was
a stupid idea. Instead, the already existing fCheckCookie member is used.
* bfs_ioctl() now accesses all userland buffers safely, this should help with
#3264, and move the crash where it belongs.
* Changes not yet tested; they only affect checkfs.

* checkfs is now also able to fix name mismatches (when the inode contains a
different name than the directory entry pointing to it). The BeOS BFS is known
to create such problems from time to time.

* Changed the way the BFS_IOCTL_UPDATE_BOOT_BLOCK ioctl works; it's a bit
more flexible to use now.

* BFS now always writes back the whole block when it writes the super block.
* Therefore, I've added an I/O control that let's it update the boot block
part of this block, so that makebootable can use it on a mounted volume
(this will probably be moved into a disk system API later).
* Added user_memcpy() to the fs_shell.
* Minor cleanup.

Got rid of vnode_id and mount_id, replaced with ino_t and dev_t.

* Prepared the BFS sources to be used with the new FS shell:
- Moved all inclusions of system headers into a new
system_dependencies.h header, which conditionally either includes
these or the FS shell headers.
- Fixed compiler warnings related to printf-like functions (int32 is
int, not long on non-BeOS platforms).
* Build a new bfs_shell. Compiles and links, but does nothing ATM.

Added a simple magic field mechanism to make chkbfs calls a little more safe.

This file defines the private BFS ioctls to control the "chkbfs" mechanism
and other stuff.
