replace PBF_NONE with an inverted PBF_DONE, so it's like all the other
flags.

writes.  In addition flush the disk cache on fsync if the sync cached
operation didn't sync the log to disk (this requires some additional
bookeping in the transaction and log code). If the device doesn't claim to
support barriers, the filesystem has an extern log volume or the trial
superblock write with barriers enabled failed we disable barriers and
print a warning.  We should probably fail the mount completely, but that
could lead to nasty boot failures for the root filesystem.  Not enabled by
default yet, needs more destructive testing first.

the pagebuf had been unlocked if the buffer was delwri. At high load, this
could result in a race when the superblock was being synced that would
result the flags being incorrect and the iodone functions being executed
incorrectly. This then leads to iclog callback failures or AIL list
corruptions resulting in filesystem shutdowns.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
