Moved Block implementation to its own source file.

* Volume::Create{File,Directory,SymLink}():
- Simplified by using the new common _CreateNode(). Changed the constructors
slightly -- the block index is now set via a separate SetBlockIndex()
method.
- The block allocated for the node was not cleared. At least for directories
that is required, though.
* Added attribute support:
- Refactored/extended {open,create}_file() and DirCookie a bit, so they can
also be used for attributes/attribute directories.
- Implemented all relevant attribute FS hooks.
- Node::DeletingNode(): Changed interface (it creates the transaction(s) as
needed, now and doesn't return the error code anymore. The base class
implementation frees the attribute directory, the Directory implementation
also unlinks all entries and frees the entry tree.
* checksumfs_write_stat(): B_STAT_MODE was not handled.

Added node monitoring support.

Implemented hooks write_fs_info(), sync(), set_flags(), fsync(), access().


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37595 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added some stat data setters.
* Added virtual methods needed for files.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37506 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added Transaction class which wraps a block cache transaction and performs
all other operations required to roll back a transaction. Transactions are
fully serialized -- due to limitations of our block cache and also to keep
things simple.
* Use a transaction for all write operations.
* Implemented the directory entry management code (a simple tree algorithm).
* Finished/implemented the FS hooks for directory entry lookup, directory
iteration, creation, and removal.
* Added non-persistent support for node access times.
* Set the user and group IDs on node creation.
* Added permission checks to several FS hooks.
* BlockAllocator::_Free(): The number of freed blocks was subtracted from
fFreeBlocks instead of added.

* Added the beginnings of node support.
* Added the bare minimum of file system hooks to mount the file system. Can't
do anything more than listing the (empty) root directory yet, though.
* Added Jamfile for building the file system for the userlandfs.
