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.

Sync with several changes in UFS/FFS: - 77115: Implement support for O_DIRECT. - 98425: Fix a performance issue introduced in 70131 that was causing reads before writes even when writing full blocks. - 98658: Rename the BALLOC flags from B_* to BA_* to avoid confusion with the struct buf B_ flags. - 100344: Merge the BA_ and IO_ flags so so that they may both be used in the same flags word. This merger is possible by assigning the IO_ flags to the low sixteen bits and the BA_ flags the high sixteen bits. - 105422: Fix a file-rewrite performance case. - 129545: Implement IO_INVAL in VOP_WRITE() by marking the buffer as "no cache". - Readd the DOINGASYNC() macro and use it to control asynchronous writes. Change i-node updates to honor DOINGASYNC() instead of always being synchronous. - Use a PRIV_VFS_RETAINSUGID check instead of checking cr_uid against 0 directly when deciding whether or not to clear suid and sgid bits.

Add read-only support for extents in ext2fs. Basic support for extents was implemented by Zheng Liu as part of his Google Summer of Code in 2010. This support is read-only at this time. In addition to extents we also support the huge_file extension for read-only purposes. This works nicely with the additional support for birthtime/nanosec timestamps and dir_index that have been added lately. The implementation may not work for all ext4 filesystems as it doesn't support some features that are being enabled by default on recent linux like flex_bg. Nevertheless, the feature should be very useful for migration or simple access in filesystems that have been converted from ext2/3 or don't use incompatible features. Special thanks to Zheng Liu for his dedication and continued work to support ext2 in FreeBSD.
