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.
