webadmin: fix regression in alarm deletion filter

Patch 6344 introduced a regression in the webadmin alarms
management which prohibits the deletion of entries.

See http://rb.dcache.org/r/6344.

which forced a range limit on the number of
entries returned by a query.  JDO does not allow
a range to be specified this way on a deletion query,
but this case was overlooked.

This patch remedies the oversight.

Testing:

Deployed with patch; successfully deleted checked entries from table.

dcache-webadmin: fix pool queue plot grid placeholder image

The pool queue plot grid is computed to find the best square fit up to 8 X 8 of plots.
This means that there will remainders (blanks) for all but the square cases.
Previously the placeholder was an empty symbol denoting no pool, but this particular
image was not the right size and at any rate was rather ugly.

The patch replaces the previous image with a simple blank image the same size as the plots.

pool: Fix race condition that leads to orphaned files

Using FileNotInCacheException cause the chimera registration to be cleared.
Clearly we don't want this when the file is actually in the pool and just
happens to be in a state in which it isn't accessible.

This patch changes the exception to LockedCacheException.

This is an alternative to patch: https://rb.dcache.org/r/5801

Suppress nfs' file protocol from being published

The dcache-info-provider publishes all doors as endpoints by default. A
couple of doors are already configured to be excluded from this, but the
nfs door isn't and causes an file://xyz/ endpoint to be published.

pool: Account#allocateNow() should trigger sweeper to get some space

Currently, Accoutn#allocateNow() utilize only free space, but does not
uses reclaimable space. As a result allocateNow will fail on pools with

This change makes sure, that sweeper get informed about the requested space.

The classic dcache behavior it to block if there is no space available to write requests.
This strategy is not always matches clients expectations.

delegation-shell: generate delegated credential of correct type

There are several types of proxy credential.  Currently the delegation shell generates
a fixed type.

In practise, the chain of proxy certificates must be of the same type or some services
will reject the chain.

This patch updates the delegation client so it generates a certificate of the same
type as the most recent (top-most) proxy certificate.
