This reverts commit e2303ef4.

[FIXED JENKINS-13695]

This code was originally developed for analysis-core plugin, but I think it's useful outside it.
I'm promoting this up to core

Passive agressive messaging
Thanks

Preserve in-progress builds when reloading a job.
Because in-flight builds tend to update the state a lot, with this
change we refrain from reloading those builds from the disk.

This should be acceptable since we are primarily reloading a job, and
reloading of builds are secondary.

All top-level jobs show up in search, as opposed to just jobs in the
current view or in the primary view.

This reverts commit ebc6af72.

The actual meat of the change is in remoting.

I couldn't quite find one place to do this, so it's spread apart
somewhat.

The proposed fix https://github.com/buckett/jenkins/commit/eec16f1b6156aea76bd0cc6e0262538713ebffb6 has a problem in that it'd allow anything that has the given URL name as a prefix.

Fix UtilTest and replace ampersand in method encode too
Thanks !
