Ashod Nakashian f52fa89036 Build-time configurable WSD limits
The server can now be configured at build time
to limit the total number of connections and/or
the number of open documents, at a given time.

./configure --with-max-documents=10 --with-max-connections=20
will limit the number of documents to 10 and total
number of connections (on one or all documents) to 20.
