b155d0dbe4 ftruncate() technically lives in unistd.h
It should be included to prevent warnings on some compilers.

789baf33a1 Make Db interfaces take varargs.
This makes it much more flexible, at the expense of making it a little
more fragile. I can think of a number of scenarios where we'll have
paths that have variables in multiple spots, and I don't want to do
sprintf() magic every time I need to access an object at one of those
paths.

cd584c1e93 Lock objects on disk if they're locked in memory.
This requires hanging onto an open file handle, and doesn't require
explicit unlocking, because POSIX says files are unlocked when their
descriptors are closed.

07f4ecd2d7 Make a number of improvements to cache handling.
- Items that are too big for the cache are now no longer immediately
  evicted; everything else is. This is probably not desirable, but it is
  not unexpected.
- Multithreading now should work as expected; DbRefs are locked before
  they are updated from the disk, and they are not evicted from the cache
  if they are locked by another thread.
- The cache may be no smaller than 1024 bytes. Previously the caller of
  DbOpen() could choose to disable the cache, and provisions were made in
  the code to support this, but this is now no longer possible because
  without the cache, there would be no way to know what files were open,
  which could lead to a race condition if two threads open the same file.
