Some web servers provide both 'Content-Encoding : "gzip"' and
'Content-Type : "application/x-gzip"' HTTP headers on their ".gz" files.
This was annoying to fail on such resources which are not so uncommon,
while non conforming (see RFC 7231 section 3.1.2.2 for
"Content-Encoding" header specification
https://tools.ietf.org/html/rfc7231#section-3.1.2.2)
This allow large files parsing and preview, while preventing unwanted
OutOfMemory errors which are likely to occur when adding to the Solr
Index resources larger than configured crawler limits.
Thus enable getpageinfo_p API to return something in a reasonable amount
of time on resources over MegaBytes size range.
Support added first with the generic XML parser, for other formats
regular crawler limits apply as usual.
Recursive processing was removed in commit
67beef657f, but one remained for anchors
content(likely omitted from refactoring). It is no more necessary :
other links such as images embedded in anchors are currently correctly
detected by the parser.
More annoying : that remaining recursive processing could lead to almost
endless processing when encountering some (invalid) HTML structures
involving nested anchors, as detected and reported by lucipher on YaCy
forum ( http://forum.yacy-websuche.de/viewtopic.php?f=23&t=6005 ).
As reported by davide on YaCy forums (
http://forum.yacy-websuche.de/viewtopic.php?f=23&t=6004 ) when the
system is on high load, unless reading carefully YaCy configuration
file, it could be difficult to understand why remote search results are
not fetched.
On content size known from HTTP headers, terminates connection faster
and improves error reports quality by reporting relevant message
"Content to download exceed maximum value..." rather than previously "no
response (NULL) for url...".
Otherwise on a malformed getpageinfo_p XML response (from the browser
point of view), JavaScript errors where thrown and the ajax status
steering wheel remained displayed indefinitely.
For faster processing (measured about 2 times faster on many real-world
examples) and more advanced detection (previous algorithm detected only
URLs separated from the rest of the text by a space character).
Especially for Turkish speaking users using "tr" as their system default
locale : strings for technical stuff (URLs, tag names, constants...)
must not be lower cased with the default locale, as 'I' doesn't becomes
'i' like in other locales such as "en", but becomes 'ı'.
This parser adds support for any XML based format other than already
supported XML vocabularies such XHTML, RSS/Atom feeds... It will
eventually be used as a fallback if one of these specific parsers fail,
before falling back to the existing genericParser which extracts not
that much useful information except URL tokens.
Removing the keystore password will prevent ssl from working after the next restart. The certificate password should be removed instead.

This prevent rendering a big and inconvenient scrollbar on resources
containing many links.
If really needed, preview of all links is still available with a "Show
all links" button.
Doesn't affect the number of links used once the crawl is effectively
started, as the list is then loaded again server-side.
