95839f5c92 The file cache now has another init method that is called after the boot 
device becomes available.
Currently, it opens the "launch_speedup" module (if available), later it
should consult a settings file for what to do.

11a3346caa The file extent map is now cached as well. Code is not optimal yet, and almost not 
tested for fragmented files - but it seems to work good enough for now.

b72cf2601f Renamed vfs_vnode_acquire_ref() to vnode_acquire_vnode(). 
Removed vfs_vnode_release_ref(), as vfs_put_vnode() already does the same thing.

186857529e cache_prefetch() now comes in two flavours: one with a direct vnode pointer, 
the other one with usual device/inode ID pair.
Both versions now accept an offset/size pair to specify the region of the
file to be prefetched - this may be turned into a file_vec_io array later on.

c9955bf00a Added new but empty function file_cache_invalidate_file_map(). 
This is needed in case the on-disk representation of a file changes (due to reorganization/defragmentation).

2a1492f0fa Moved the definition of the BlockAddressPool class into block_allocator.cpp, as it's 
not used outside of it.
Added tracking for the last transaction in the block cache; that way it can test
if the last transaction has been closed before opening a new one.

584d673049 Fixed various bugs in the block allocator: new free ranges were never added 
to the free list, so a new range was started for every allocation (!).
block_range::Free() did not update the chunk's used_mask correctly.

317121e102 Work in progress of the new block allocator for the block cache. It works, but 
currently needs even more memory than the old one 8-)
Not cleaned up at all.

f4e5c34143 cache_abort_transaction() freed the wrong block, and thus causing a file system 
corruption even better than during its absence.

b3ef4fb41a Oops, forgot to implement cache_abort_transaction(); every failing transaction 
could have destroyed the BFS integrity... (just happened to me, that's how I
noticed it)

d5b04e50f8 First step into a new block allocation strategy for the block_cache 
(right now, it's still malloc/free, just encapsulated in an allocator class).

718b5114e0 This should fix the build after all the kernel/system renaming. 
If anything is still broken (and was not before :)), please shout.
