This is simpler to calculate and the advantage of using a prime is
negligible anyway.

44f55e1866 util/IntrusiveList: add missing initializer to insert_after() 
We must not call std::next() if the list head was not yet initialized.
This was missing in commit 7065425927

3e09f95b40 tag/Pool: enable option zero_initialized 
Commit 44beae519d caused the MPD
executable to grow by more than 1 MB because the `slots` array
suddenly was not zero-initialized anymore, because the doubly-linked
list is circular, while the singly-linked list is zero-terminated.

This option moves the array back to the `bss` section.

1f495efb46 test/LoadDatabase: ignore tag/charset mismatches 
This program shouldn't fail just because the configuration doesn't
match - it has no configuration, it's just a dumb test program.

83a6cb804b util/IntrusiveHashSet: add template argument GetKey 
This is a big simplification of all IntrusiveHashSet users: instead of
having to implement multiple overloads of Hash and Equal, the
IntrusiveHashSet class can first extract the effective key from an
item and then pass it to the Hash/Equal functions.

2cd5f4cd3e util/IntrusiveHashSet: replace template parameters Hash/Equal with a single one 
Preparing to add a key extraction function.  Without this "Operators"
template parameter, we'd have even more template parameters, and that
parameter list would grow too complex.  Better wrap it in one single
template that contains all operators.

This is an API change which all callers need to adjust to, but it will
be worth it.

aeadae5399 util/IntrusiveHashSet: insert_check() returns the bucket head on success 
The list head is a stable value that is guaranteed to be still valid
when insert_commit() gets called.

This fixes a linked list corruption bug in class StaticCache which
occurs when the cache item pointed to by the iterator gets evicted
between insert_check() and insert_commit().
