Before this patch we had 3 loops walking a hash chain to delete
records:
tdb_do_delete() to find the predecessor of the record that was to be
deleted. tdb_count_dead(), the name says it all and tdb_purge_dead()
to give back all dead records from a chain to the freelist.
This patch introduces tdb_trim_dead that walks a hash chain just
once. While it does so it counts the number of dead records, and all
records beyond tdb->max_dead_records are moved to the freelist.
Normal record deletion now works by always marking a record as dead in
step 1 and then calling tdb_trim_dead. This is made safe against
circular chains by doing the slow chain walk only in the case when we
did not delete a dead record during our walk.
It changes our dynamics a bit:
When deleting a record with non-zero max_dead_records, now we always
leave that number of records around when deleting, doing a blocking
lock on the freelist when we found too many dead records.
Previously when exceeding max_dead_records we wiped all dead records
to start accumulating them from scratch, assuming we could lock the
freelist in a nonblocking fashion.
The net effect for an uncontended freelist is the same: In
tdb_allocate() we still completely hand over all dead records to the
freelist when we could lock it, it just happens later than without
this patch.
This means for a lightly loaded system we will potentially leave more
dead records around in databases like locking.tdb. However, on a
heavily loaded system we become more predictable: If the freelist is
so heavily contended that across many deletes we can't get hold of it,
previously we accumulated more dead records than max_dead_records
would allow. This is a really lowlevel tradeoff that is likely hard to
measure, but to me becoming more deterministic without sacrificing too
much parallelism (we keep more dead records around) is worth trying.

The next commit will change the handling of dead records, removing the
"tdb_do_delete" function. As traverses should not happen in normal
operations, dead records from them should be rare, and relying on
traverses to remove them is a very bad idea IMHO.

Turns out that there exist AppleDouble files with an extended FinderInfo
entry that includes the xattr marshall buffer, but the count of xattrs
in the buffer is just zero.
We do want to discard this extended FinderInfo entry and convert it to a
simple fixed size FinderInfo entry, so remove the check.

This is not always going to work, and is not guaranteed to be
consistent even between minor versions.
Here is a simple counterexample:
>>> a = 'hello'
>>> a is 'hello'
True
>>> a is 'hello'.lower()
False
>>> a == a.lower()
True
Possibly it always works for the empty string, but we cannot rely
on that.

Python's property() function works like this:
property([getter[, setter[, delete[, doc]]]])
but we have been forgetting the delete function, or rather setting it
to be a string. A string is not callable and is unlikely to succeed at
deleting the property.
