f613f4f2df (array) Fix spurious search results
This was caused by a bug in the binary search algorithm causing it to sometimes return positive values when encoding a search miss.

It was also necessary to get rid of the vestiges of the old LongArray and IntArray classes to make this fix doable.

(index-reverse) Parallel construction of the reverse indexes. (#52)
* (index-reverse) Parallel construction of the reverse indexes.

* (array) Remove wasteful calculation of numDistinct before merging two sorted arrays.

* (index-reverse)  Force changes to disk on close, reduce logging.

* (index-reverse)  Clean up merging process and add back logging

* (run)  Add a conservative default for INDEX_CONSTRUCTION_PROCESS_OPTS's parallelism as it eats a lot of RAM

* (index-reverse)  Better logging during processing

* (array) 2GB+ compatible write() function

* (array) 2GB+ compatible write() function

* (index-reverse) We are logging like Bolsonaro and I will not have it.

* (reverse-index) Self-diagnostics

* (btree) Fix bug in btree reader to do with large data sizes

d0aa754252 (long-array) Implement java.lang.foreign.Arena based lifecycle control for LongArray.
Further de-ByteBuffer:ing of these classes is to be done, but this is the smallest most urgently needed benefit.

This commit is a WIP but in a fully working state, pushing due to the importance of the changes to offer lifecycle control over mmaps.

dbe9235f3a (*) Upgrade to JDK21 with preview enabled.
... also move some common configuration into the root build.gradle-file.

Support for JDK21 in lombok is a bit sketchy at the moment, but it seems to work.  This upgrade is kind of important as the new index construction really benefits from Arena based lifecycle control over off-heap memory.

320dad7f1a (index journal) Fix leaky abstraction in IndexJournalReader.
The caller shouldn't be required to know the on-disk layout of the file to make use of the data in a performant way.

3101b74580 (index) Move to a lexicon-free index design
This is a system-wide change.  The index used to have a lexicon, mapping words to wordIds using a large in-memory hash table.   This made index-construction easier, but it
also added a fairly significant RAM penalty to both the index service and the loader.

The new design moves to 64 bit word identifiers calculated using the murmur hash of the keyword, and an index construction based on merging smaller indices.

It also became necessary half-way through to upgrade guice as its error reporting wasn't *quite* compatible with JDK20.

460998d512 (index) Move index construction to separate process.
This provides a much cleaner separation of concerns, and makes it possible to get rid of a lot of the gunkier parts of the index service.  It will also permit lowering the Xmx on the index service a fair bit, so we can get CompressedOOps again :D

9894f37412 (index) Implement new URL ID coding scheme.
Also refactor along the way.  Really needs an additional pass, these tests are very hairy.

6a04cdfddf (loader) Implement new linkdb in loader
Deprecate the LoadUrl instruction entirely. We no longer need to be told upfront about which URLs to expect, as IDs are generated from the domain id and document ordinal.

For now, we no longer store new URLs in different domains.  We need to re-implement this somehow, probably in a different job or a as a different output.
