(crawler) Make DomainCrawlFrontier a bit less aggressive with throwing away excess links when it's approaching full.
...
Also be a bit smarter about pre-allocating queues and sets based on depth rather than the number of provided URLs, which was always zero outside of tests.

(*) Remove the crawl spec abstraction
...
The crawl spec abstraction was used to upload lists of domains into the system for future crawling. This was fairly clunky, and it was difficult to understand what was going to be crawled.
Since a while back, a new domains listing view has been added to the control view that allows direct access to the domains table. This is much preferred and means the operator can directly manage domains without specs.
This commit removes the crawl spec abstraction from the code, and changes the GUI to direct to the domains list instead.

(crawler, EXPERIMENT) Disable content type probing and use Accept header instead
...
There's reason to think this may speed up crawling quite significantly, and the benefits of the probing aren't quite there.

* Fix bug in retry-after header that assumed the timeout was in milliseconds, and then clamped it to a lower bound of 500ms, meaning this was almost always handled wrong

Refactoring keyword extraction to extract spans information.
Modifying the intermediate storage of converted data to use the new slop library, which is allows for easier storage of ad-hoc binary data like spans and positions.
This is a bit of a katamari damacy commit that ended up dragging along a bunch of other fairly tangentially related changes that are hard to break out into separate commits after the fact. Will push as-is to get back to being able to do more isolated work.

The revisit logic wasn't sufficiently dampening the recrawl rate for websites that largely have not changed.
