[FIXED JENKINS-13154] AnnotationMapper bug was causing massive lock contention when saving fingerprints.

Fixed the throughput problem between master/slave communication.
This fix contains two independent problems.

One was in the remoting. During a large sustained data transfer
(such as artifact archiving and large test reports), the way we
were doing flow control and ACK-ing were penalizing us badly.
I improved the flow control algorithm in remoting 1.23, and also
increased advertised window size so that the transfer can saturate
available bandwidth even when a latency is large. (And unless
the reader side is excessivesly slow, this shouldn't increase
any memory consumption.)

The other fix was in trilead-ssh2, which is our SSH client
implementation used by ssh-slaves plugin. The buffer size for flow
control was too small. I improved the way buffering is done to reduce
the memory footprint when the reader closely follows the writer, then I
increased the advertised window size. Again, this shouldn't increase
memory consumption (in fact it'll likely actually reduce them) unless
the reader end gets abandoned.

On my simulated latency-injected network, the sustained transfer rate is
now on par with scp. We win for smaller files because of the TCP slow
start penality that scp would incur, and we lose a bit as files get
larger due to additional framing overhead.

If you have manually extracted slave.jar and placed them on slaves, you
need to update them to 2.23 to see the performance benefits.

[FIXED JENKINS-17177] wrong build result in post build steps after failed pre build step in maven project

Made the in-flight build survive the reload from the disk.

Report 100 recent builds in the JSON API, including in-progress builds.

Not reporting all the builds since this would nullify the lazy loading
effect. Will introduce a pagenation API that supports retrieval.

Remember the permalink target as symlink (or simple text file) so that
looking that up doesn't cause the walk of the build history.
I think this is more in line with our general preference of making
$JENKINS_HOME useful (than trying to persist cache into a blackbox.)

Having a general purpose in-memory cache could be useful, so I'll see if
I can add that, too, in a way that allows someone to plug different
backend.

[FIXED JENKINS-15796] NoClassDefFoundError: 'Could not initialize class org.jvnet.hudson.Windows$MEMORYSTATUSEX' from SwapSpaceMonitor.
Not fixing actual linkage error—JNA issue of some kind—but ensuring that Jenkins reports it only once.

Integrated the new version of Stapler that includes the fix.

[FIXED JENKINS-16474] Winstone and executable WAR upgraded to actually support --httpKeepAliveTimeout.

These are one time URLs, and this change aligns them from other /static/
links that serve 365 days expiration period.

[FIXED JENKINS-17087] getSortedDescriptorsForGlobalConfigUnclassified needed to avoid clobbering GlobalCrumbIssuerConfiguration in Jenkins.doConfigSubmit.

(Ah, the joys of dynamic typing!)

Disable authenticode verification on jenkins.exe and jenkins-slave.exe
by generating a proper application configuration file.

Added backward compatible data loader and a corresponding test case.

HyperlinkNote shouldn't emit the absolute URL.

b5ed3199 already caught linkage errors but then unconditionally returned false from Util.isSymlink, which is wrong;
we want to fall back to the generic File.canonicalPath comparisons in this case.
