fb39a31ca7 Fixed a dead-lock that could happen if an attribute was changed and you
had some running live queries.
SimpleLock now allows nesting; added some missing atomic operations to
make its implementation as easy as possible.

b71ba910ba The non-benaphore of the Semaphore class just didn't work correctly...

dab62fa391 Fixed a big stupid bug that can cause lots of trouble: all locks created
weren't moved to the kernel (as owner), so they would be deleted after
the team which almost randomly created them died.
Benaphores are now only used if USE_BENAPHORES is defined - I have renamed
the Benaphore class to Semaphore to take the changed behaviour into account.
Added a Status() method to the Locker class.

820dca1912 Rearranged some code in the BlockAllocator; AllocationGroup now has Allocate()
and Free() methods which operate on the AllocationBlocks.
BlockAllocator::AllocateBlocks() couldn't correctly reserve space for allocation
groups with more than 2 blocks - AllocationGroup::Allocate() now can, which
is now used by AllocateBlocks() (but it's slightly less fast).
Began implementing functionality for a chkbfs-like command.
Some style changes.

7ab95d9da9 Made it easier to switch from R5 compilation to the test "obfs" compilation.
$ COMPILE_FOR_R5=1 jam
will compile the "bfs" version, otherwise the "obfs" version is created.
Note: the final executable will always be called obfs (for now).

2b5451f164 Added private non-implemented copy constructor and assignment operators
for many classes for the sake of completeness.
Added a Transaction::IsStarted() method to not let it look like as if the
transaction is started more than once.
Changes made after suggestions from Mike Nordell, again :-)

d801dfdd1c Added CachedBlock::BlockSize(), and CachedBlock::BlockShift() methods as
suggested by Mike Nordell.
Some code cleanups, added a comment in Inode::SetFileSize() to point out
that Stream<Cache>::WriteAt() denies growing the file size its own.

free anything if it couldn't acquire the semaphore.

b8cb2cade8 B_CUR_FS_API_VERSION must be 2 on R5; so you need to build it on Dano if
you want to use it for booting Dano.

ccc09203a5 Added power management functions to support Dano (needed to boot Dano using
our file system):
- added bfs_wake_vnode(), and bfs_suspend_vnode()
- bumped B_CUR_FS_API_VERSION to 3 as needed for Dano

It should now be able to boot Dano with our BFS, although I haven't tested
it. The information was gained using some degree of reverse engineering...
It won't be part of the BFS implementation for OpenBeOS (that won't run on R5
anymore) :-)

is no only "-O1", since gcc obviously produces bad code if compiled with more.

a130fd5520 Inode::SetFileSize() now doesn't allow changing the file size of uncached
files anymore (only Inode::WriteAt() denied it before).
Introduced a BFS_NAME define to be able to switch easier between "obfs",
and "bfs".
bfs_write_stat() didn't return the error code if Inode::SetFileSize() failed;
instead, it always reported success.

b98d9a335a Fixed two bugs in the block allocator:
- the maximum number of blocks a block_run can cover is 65535 not 65536
- allocations over a block boundary in the block bitmap always failed due
  to a incorrectly handled status

Both bugs could prevent BFS to create the VM swap file which led BeOS to
stop booting under certain circumstances.

ae38c6e93d Fixed a bug that could lead to the wrong last_modified time in an inode;
bfs_close() updated the last_modified time & index, but it didn't write
the inode back to disk.
Furthermore, bfs_write() should have already updated the last_modified
time, not bfs_close.

40f7fd6cf3 Implemented the basics to allow uncached file access under BeOS.
This is needed for the VM swap file and if you want to mount disk images
located on the BFS volume.
There is now a BufferPool class that manages a pool of buffers, so that
Inode::ReadAt()/Inode::WriteAt() can access a file without having to use
the cache or malloc()/free().
The real uncached file access is not yet implemented, though.
