Normally, when each client view closes, the
session count is decremented until the last
view is closed. However this doesn't work
when the kit child process terminates.
Due to a race condition between the last
client disconnecting, and the internal
structure destructing, and the next
client connecting (on the same doc),
the Admin loses track of the doc and pid.
This is an issue of assuming a document
and its pid are unique and will always
remain unchanged.
This patch adds a new API to remove a
doc and all its views unconditionally
to try to avoid the above issues.

The logging functions already display the thread name on all output
lines. No need to mention it another time in the thread start and
finish logging messages.
Much better than assuming that errno would be relevant at all
Log::error() calls (or alternatively, having to remember to append a
false parameter to the Log::error() call, which had not been done a
single time anyway.)
Call log::syserror() right after a system call has returned an
error. Don't call it otherwise.
Admin no longer needs a pipe as it's notified
from WSD. It is now a singleton with improved
locking.
The tracking of documents and views still needs
improvement and corrections.

This reverts commit 97c8f35ddf.
Since the Broker design has been extremely simplified,
all communication between Broker <-> Kit are gone.
Only a pipe between WSD and Broker remain.
Temporarily reverting this to apply the Broker redesign,
after which this patch can be reviewed and merged.
This will be easier than trying to merge the redesigned
Broker on top of this.

By default, queries and stores the total memory usage in
AdminModel every 5 seconds, and caches the last 100 such values.
Both cache size and interval can be changed by simple commands
from the clients.

Further changes/refactoring to make it possible:
* Add broker pid to Admin class
* Move getMemoryUsage for process to Util
* Change variable name to accurately reflect *active* items
_nViews -> _nActiveViews, etc.

Admin web sessions are added as subscribers to AdminModel. Live
notification fill up the AdminModel, and notifies to
subscribers, if present any. AdminModel can also be queried to
fetch any previous data since the start of the server including
expired documents/views with timestamps for analysis.
There is lot of stuff that can be added in future. This commit
just lays the foundation of appropriate classes.
