This is a hard requirement to be able to migrate
to a more recent jetty version, which may happen sometime soon.

We will use the default value for now on.
This is much better for resource economy and fits better into a
container/docker/kubernetes strategy.
Furthermore, a small memory footprint is essential for the usage on
small devices like RaspberryPi.

TLS Server Name Indication (SNI) extension activation can now be
configured with the new Settings_p.html?page=httpClient administration
page.
SNI extension is also now enabled by default, as in 2019 the
unrecognized_name(112) alert is more properly handled by major web
servers TLS implementations, following the RFC 6066 standard.

Indicator) support for https connections from code to startup script allowing admin to ~easy/transparent alter the YaCy default FALSE setting.
Background: some user report problem with connecting/crawling some sites via https which require SNI support (by default switched off in YaCy). On the other hand systems not demanding SNI support are sometimes not properly configured and due to a bug/feature in java 1.7 connection is aborted. The later is more often the case, so the default is still fine. With the java start parameter expert user can no alter the startparameter to -Djsse.enableSNIExtension=true (java default) if they crawl more hosts requiring SNI support.
The alternative to let YaCy try both during https handshake (deep inside the httpclient) is not pursut at this time.

- useful for remote installation to set any config file property
- multipe parameter can be set at once, on Windows enclose parameter in doublequotes
- special handling "adminAccount=adminuser:adminpwd" sets adminusername and md5 encoded admin-pwd
- adjusted windows startbatch to allow command line parameter handling
- remove not needed classpath calculation from startYACY_debug.bat

YaCy has to be installed to a directory with write access for the
running user.
DATA folder is now used in the YaCy folder again.
For using another location, the start script has to be heavily modified
for loading proper start parameters after YaCy has been started once.

reason: -XX:ReservedCodeCacheSize=1024m may be too large (introduced in 7823)
error message: could not create virtual machine
there are more differences from the _debug.bat start script for the start parameters
please check whether they are needed:
-Xss256k -XX:MaxPermSize=256m -XX:+UseAdaptiveSizePolicy

after appearance of a malloc error together with a crash of the jvm which stated at the end of the log:
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 32756 bytes for ChunkPool::allocate
# Possible reasons:
# The system is out of physical RAM or swap space
# In 32 bit mode, the process size limit was hit
# Possible solutions:
# Reduce memory load on the system
# Increase physical memory or swap space
# Check if swap backing store is full
# Use 64 bit Java on a 64 bit OS
# Decrease Java heap size (-Xmx/-Xms)
# Decrease number of Java threads
# Decrease Java thread stack sizes (-Xss)
# Set larger code cache with -XX:ReservedCodeCacheSize=
this follows the last two points in the list of recommendations. To set appropriate values the default values from

- added some clear statements that shall clear static cache size within the pdfbox library
- the pdfbox library contains a memory leak; it is unsafe to run a peer with pdf parser permanently on.

when a ant dist is envoked, the release is built using the new yacycore.jar without the class files in classes
YaCy consists currently of two main parts: the YaCy core and the YaCy interface. This change will make it
possible to use the YaCy core as part of other projects.

* do not set shortcuts to the YaCy search page because we have a tray icon now. the user will not get an error if yacy doesn't run.
* do not set a shortcut do debug start. usual users don't care about logs.

pleas disable before release because 2nd update fails at the moment
and commandline handling has to be improved for windows
* update via new unTar class
please review stream- and exceptionhandling because I'm fairly new to Java
maybe it can be done concurrent
* updated windows startscripts to values from yacy.init
