Move SHA256 class to libroot instead of linking libshared into libroot.

Discussed with PulkoMandy and on the haiku-commits mailing list.

Thanks to @jessicah for compile-testing and fixing 2 small issues I missed.

Moved Block implementation to its own source file.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37633 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added node monitoring support.

* Added a File class for representing regular files. We use a simple block tree
for the data management. Reading/writing (using file cache and file map) is
implemented, but not exactly well tested yet.
* Renamed SymLink::{Read,Write}() to {Read,Write}SymLink().
* Implemented FS hooks write_stat(), create(), read(), write(), io().
* Added O_TRUNC support to open() hook.

* 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.

* Moved the checksum device driver to subdir "driver".
* Created a file system module and a disk system add-on. Currently only
initializing and identifying/scanning is supported.
