As reported by Palulukas in YaCy forum
(http://forum.yacy-websuche.de/viewtopic.php?f=18&t=5944&sid=dcef5b899ab4aa9b40e3a3d158c13aed#p33454)
the Index Export operation can fails, notably when the Solr index
contains one or more documents with empty (despite required)
"load_date_dt" field.
This fixes the export failure when the situation finally occurs, but
more should be done to harden verifications on minimum required fields.

Add some javadoc, and not needed remove of omitted fields in postprocessing.
As noticed by @reger24, abusive use of OpenSearch systems should be
prevented, especially if allowing to parse and reuse HTML results.
robots.txt file is now checked before requesting an external OpenSearch
system to respect the host exclusions and eventual crawl-delay value.
The check is also performed when trying to add a new OpenSearch URL
template through the /ConfigHeuristics_p.html admin page.
Many OpenSearch systems do not provide results as standard RSS/Atom
feeds but only as HTML.
This modification add some support for custom OpenSearch HTML results
through the use of mapping files (as already done for federated Solr
search) relying on CSS-like selectors to retrieve information from HTML
content.
An example mapping file is provided to map results from the
www.npmjs.com OpenSearch URL.
For a more reliable Docker image build, also switched to the ant archive
repository to fetch the needed binary as other repositories only provide
the latest versions.
As discussed in PR #93 with @JeremyRand and @reger24 this new advanced
settings page includes:
- a new setting to control remote Solr responses encoding
- some existing debug settings which could not be set through the admin
user interface
On timeout, closing remote Solr requests is proper than simply using
Thread.interrupt() that is not effective in most cases. Closing does not
ask commit on remote solr, but release http connections resources and is
more likely to end those threads that can else wait indefinitely.
Other related improvements included :
- no more marking remote peer as not available when remote search is
interrupted before timeout by the cleanup job.
- added a short fine log level trace of failing remote solr requests
This property has been deprecated four years ago by commit
d74472f562. For any active search event
id, it was then always filled with "-UNRESOLVED_PATTERN-".
This is to be more easily understandable and to reflect more accurately
the current memory strategies implementations that eventually set the
"proper" state not only because DHT reception.
As described in mantis 725 (http://mantis.tokeek.de/view.php?id=725) the
HostBrowser.xml api directory entries had incorrect count attribute
value.
This was because the HostBrowser html page and backing template servlet
evolved, but modifications were not reported on the xml api.
This will prevent mistakenly hiding a div element not designed to be an
infobox but having a ".info" parent (After having previously added the
possibility for a div - and not only a span element - to be an infobox).

To assemble the original link url for out-/inboundlinks, icons and pictures
the *_protocol_sxt and *_urlstub_sxt is needed (due to the used data-reduced

to be able to correctly assemble the original link url.
As mentioned in issue #103, control settings over YaCy disk usage
already existed but lacked a user-friendly way to set them.
I added it to the Performance_p.html administration page with a little
refactoring on the "Resource Observer" fieldset for improved
accessibility and HTML standards respect.
Also added the possibility to enable/disable the autoregulation fonction
from this page.
Made use of ol, li, thead, th, tbody, h1 and h2 html tags.
Added aria-label attributes to provide alternative textual information
previously only conveyed by color cue.
Tested behavior with NVDA 2016.4 screen reader.
As reported by @tglman on issue #90, when searching images on the local
index only, pages next to the first were always empty. This was a
regression from commit c25e48e969.
Also removed deprecated HTML attributes uses.
Validation performed with Nu Html Checker 17.1.0.
Cross browser tested with :
- Debian Jessie : Firefox ESR 45.6.0
- MS Windows 10 : Firefox 50.1.0, Chrome 55.0.2883.87, MS Edge
In the /HostBrowser.html page "only hosts with urls pending in the
crawler", "only with load errors" and "Administration Options" all
require administration credentials. But they were displayed even to
unauthenticated users, and clicking them did nothing and returned the
/HostBrowser.html page empty.
