fs_shell: Prevent inclusion of BSD headers; fix DeviceOpener.

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.

bfs: removed kernel_cpp.h's new operator.

* This fixes bug #9715 from the POV of BFS, ie. the new operator seems
to call the constructor on a NULL object on failure.

* Added support for O_NOCACHE/O_DIRECT.
* bfs_open() was leaking the already allocated cookie in several error
conditions.

* Changed the inode write locking to be held as long as the transaction is
running - this fixes several cases where someone could see outdated data
when a transaction had to be reverted (the time between unlocking the inode
and actually reverting the blocks). For that, Inodes can now be put into a
singly linked list.
* Added a TODO in Inode::WriteAt() which explains why it cannot use the above
method: seems that our VFS/VM locking model isn't really that good.
* Fixed a possible deadlock in Attribute::_Truncate() where the inode write
lock was held before starting the transaction.
* Added an InodeReadLocker convenience class, that should be used instead
of ReadLocker - Inode::Lock() only still exists because of the needs of
bfs_io().
* Moved the bfs_io() callback hooks out of the exported module API region,
and removed their bfs_ prefix.
* Added a Volume::IsInitializing() method that should be used rather than
checking if Volume::ID() is >= 0.
* Removed the MultiInodeLocker again, as it's pretty much superfluous now.
* Moved openModeToAccess() to the Utility.h header.
* Minor cleanup.

* The bfs_shell needs to include <new> as well.

* bfs_fsync() no longer grabs the Inode's read lock - instead, Inode::Sync()
will take care of the locking.
* Use new(std::nothrow) over new, and malloc (only in kernel_interface.cpp);
the kernel_cpp.h header isn't really necessary anymore, so there is no reason
BFS should continue to use it.
* Removed superfluous NULL checks.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26574 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Removed the home-brewn locking classes in BFS besides the read/write lock
(for now).
* Inode::fSmallDataLock is now a recursive_lock, Journal::fLock is now
a recursive_lock, too, Journal::fEntriesLock is now a mutex, as is
BPlusTree::fIteratorLock.

* Made the additions of the KDL debugger commands independant from the
DEBUG macro; they are now added only if BFS_DEBUGGER_COMMANDS is
defined (which is now done by default in the Jamfile).
* Added "bfs" KDL command which dumps volume information and the super
block.
* Made use of the new tracing API to trace block and inode actions
(and the new AbstractTraceEntry class I forgot to mention in the last
commit). Is compiled in only when BFS_TRACING is enabled (defaults to
off in the standard builds).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23464 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Fixed a bug in CachedBlock::Unset() that would call block_cache_put() on the same
block everytime it's called - that caused negative reference counts in the block
cache, causing all sorts of problems once they were flushed.
* Changed order of includes in system_dependencies.h to what I prefer: descending from
private to public (resp. from most specific to most generic) headers.
* Minor cleanup.

* 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.
