Trevor Thompson 54f5c3b6ec [NTFS] - Begin to implement B-Trees. Allow for creating several new files in a directory.
NtfsAddFilenameToDirectory() - Add CaseSensitive parameter. Update to use new B-Tree code: First, the index is read and converted to a B-Tree in memory. Next, a key for the new file is inserted into the tree. Finally, the tree is converted back to an index root attribute which is written to disk.
+btree.c - Includes functions related to B-Trees (AKA B*Trees).
ntfs.h - Added several structures for representing B-Trees in memory.
Known limitations: For simplicity, only trees with a depth of one are currently supported (i.e. an ordered list of filenames). Directories that have or will require an index allocation to store all their filenames are still TODO. As a consequence, the user will only be able to create about 6 files in a directory.

Trevor Thompson 8bb62e20d3 [NTFS] - In the NtfsAddFilenameToDirectory() function, rename DirectoryContext parameter to the more descriptive, and accurate, IndexRootContext (to simplify the next commit).

Trevor Thompson 032be02954 [NTFS] - Fix POSIX rules. Fix accessing long filenames created in Windows when 8dot3 name creation is disabled.
Whether or not a filename should be interpreted as case-sensitive is dependent on a flag passed to the driver when a file is created (opened); it's separate from the namespace associated with the file being accessed.

Trevor Thompson e0048b1362 [NTFS] - Add the most basic support for file creation. Expand diagnostic output, especially in NtfsDumpIndexRootAttribute(). Replace an ExFreePool() with ExFreePoolWithTag().
AddFileName() - Add a parameter to receive the Mft index of the parent directory. Fix so the name of the file will be stored in the attribute, not the name of the directory.
NtfsCreateFile() - Open a file that was successfully created, instead of assuming failure.
NtfsCreateFileRecord() - Add the filename attribute of the created file to the parent directory's index.
+NtfsAddFilenameToDirectory() - Adds a $FILE_NAME attribute to a given directory index. Presently, a file can be created in an empty directory only.
AddNewMftEntry() - Add a parameter to receive the mft index where the new entry was stored.

When writing to a file, increase the file size if trying to write past the end.
*FindAttribute() has been given an optional pointer to a ULONG that will receive the offset of the found attribute from the beginning of the record. This is to allow for found attributes to be written back into their file records.
+SetAttributeDataLength()
+UpdateFileRecord() - Updates a file record in the master file table at a given index.
+AddFixupArray() - Prepares a file record or directory index for writing to the disk.
