Bring in the ext2fs work done by Aditya Sarawgi during and after Google Summer

of Code 2009: - BSDL block and inode allocation policies for ext2fs. This involves the use FFS1 style block and inode allocation for ext2fs. Preallocation was removed since it was GPL'd. - Make ext2fs MPSAFE by introducing locks to per-mount datastructures. - Fixes for kern/122047 PR. - Various small bugfixes. - Move out of gnu/ directory. Sponsored by: Google Inc. Submitted by: Aditya Sarawgi

File flags handling fixes for ext2fs:

2009-11-05T04:51:38Z

- Disallow setting of flags not supported by ext2fs. - Map EXT2_APPEND_FL to SF_APPEND. - Map EXT2_IMMUTABLE_FL to SF_IMMUTABLE. - Map EXT2_NODUMP_FL to UF_NODUMP. Note that ext2fs doesn't support user settable append and immutable flags. EXT2_NODUMP_FL is an user settable flag also on Linux.

- Style(9) improvements.

- Convert all K&R definitions to ANSI equialents. - Retire bsd_malloc and bsd_free macros and use malloc/free directly. - Drop some unused debugging calls. This commit brings no functional changes.

- Sync our copies of ext2fs Linux headers to current Linux versions.

Minimize differencies between our ext2fs headers and relevant Linux versions by using EXT2_SB macro to access the superblock fields. Most of the differencies in access to these fields are now hidden inside this macro. - Rename the s_db_per_group field of ext2fs_sb_info to s_gdb_count to reflect the similar change in Linux headers. New name also seem to be more appropriate for this field. - Use proper types for s_first_inode and s_inode_size in-core superblock fields. Now they reflec types used in the on-disk superblock version. - Add support for older filesystem revisions that doesn't have proper s_first_ino and s_inode_size fields in the on-disk superblock. In these cases predefined values for these fields are used. - Add simple sanity checks for s_first_inode and s_inode_size correctness. Reviewed by: bde (previous version) MFC after: 2 weeks

the VFS. Now all the VFS_* functions and relating parts don't want the context as long as it always refers to curthread. In some points, in particular when dealing with VOPs and functions living in the same namespace (eg. vflush) which still need to be converted, pass curthread explicitly in order to retain the old behaviour. Such loose ends will be fixed ASAP. While here fix a bug: now, UFS_EXTATTR can be compiled alone without the UFS_EXTATTR_AUTOSTART option. VFS KPI is heavilly changed by this commit so thirdy parts modules needs to be recompiled. Bump __FreeBSD_version in order to signal such situation.
