UDF: support for metadata partition (feature from 2.50)

* added Icb::FindBlock() to find block in extents.
* MetadataPartition uses extents descriptors found in the metadatafile
to lookup blocks on a physical partition
* uses struct timespec instead of time_t
* added init_entities() to call C++ structures constructors. This is
called at module initialization, C++ constructors are currently not called when
a kernel module is loaded.
* tested with a sample bluray ISO.

CID 2196: The sanity check did check the pointer size instead of the type size.

added a file system call preallocate() as described in #6285, currently unused


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39006 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Removed superfluous check, and fixed wrong indentation. This also closes
CID 1510.

* Finish the partition scanning part so that UDF is recognized and mountable.
* Added myself to the copyrights.

* Cleanup the Jamfile, this one doesn't work on BeOS anymore.
* Turn off remaining verbose debug output.
* Add UDF to the default image.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35653 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Implement udf_io and udf_get_file_map.
* Add file map and cache and do reads through the file_cache for file ICBs.
* Move the private _Read() backend from the header to the implementation file.
* Read() is now only used for directory iteration.
* Turned off the verbose debug output.
* Minor cleanup.

This fixes the abuse of the block_cache, should allow executables on UDF and
won't panic on protected content.

* UDF didn't actually initializing _flags to 0 (same as with fat).
* Set the _type as well, this gets file listings work.
* Some cleanup and debug output moves/fixes/additions.

Yet crashes when accessing files though.

Various changes to get this mostly compiling, with the exception of a template issue I don't yet completely understand.

its open_dir() implementation instead (as suggested by Ingo).
-alphabranch (it's only a cleanup)

* Most of the other file systems now maintain the st_blocks value. It might not
always be correct, but should be at least close.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27793 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added some more TRACE, eventually they will be removed
* replace sizeof(dirent) with sizeof(struct dirent) as the pointer passed was called dirent!
that would cause d_reclen to be set to the wrong value, making panic. Thanks Stefano!

I finally managed to mount and list its content.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27139 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Replaced some PRINT with TRACE
* Rename error to status
* Fix assignements in udf_read_stat
* Added udf_{close_dir,free_dir_cookie} hook functions which prevented
udf from mounting the partition

It seems mouting an udf partition works correctly but I'm still unable
to list its content.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27138 a95241bf-73f2-0310-859d-f6bbb57e9c96

* added udf_{open,close,free_cookie,access}.

Still missing something though, as it still panics with an ip 0x0


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27112 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Removing new_vnode which was commented out in favor of publish_vnode
in order to publish the root node
* fixed _RootVNodeID assignement
* Applying our coding guidelines

Mounting now goes as far as lookup, then I get a panic from w>Desktop
thread in CreateVolume -> GetRootDirectory. ;-)

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27084 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Fixed typo that prevented udf from being picked up: it's "modules", not
"module" - hope that helps, Salvatore :-)
* Fixed warnings.
* Fixed udf_identify_partition() not to crash the system when a UDF partition
is available, and also fixed it to actually not claim non-UDF partitions.
* Moved partition naming (that shouldn't be done in identify!) to
udf_scan_partition(), and corrected it (ie. use strdup(), don't copy into
a NULL pointer...), but also disabled it for now, as it needs some more
work to pass a cookie from identify now.
* Whitespace cleanup.
