General Description: Support for filtering file distribution using distreplace.

Detailed Description:

This patch enables the server to support filtering of files to be distributed to clients via
distreplace.
The dist_config_file.json serves as the mapping file that guides the server on the file that should
be sent to a client if the filters specified (os,ip,host,arch,version) matches the client
information found in the openit_client_info.json file.

If there is no client information that matches with the filters, the file distribution will proceed
as normal using what is specified in distreplace.xml.

This patch also fixes the issue where the server daemon constantly changes its PID while running.

Revision 3:

Multiple clients requesting to write the openit_client_info.json file at the same time causes
inconsistent values in json file, this patch makes the information be stored in an internal client
info (in memory) and be written to the json file every minute instead of every client's request to
better handle the situation.

Config file distribution updates:
1. Checks if the client is in the internal client info. If yes, that info is used for filtering dist
files.
2. If the client can't be found in the internal client info, the host/ip upon connection as filters
will be used. (This won't work for dist file using os/arch/version filters.)

General Description:
Site-Demo license type support for Windows Core server.

Detailed Description:
openit_server for windows does not support site-demo type license. Executing this script replaces
old openit_server with the version that contains support for site-demo type license.

General Description: The installation of this patch fixes the restarting issue of openit_server and
file transfer of different file encoding.

Detailed Description:
The database fails to update automatically because the openit_server binary restarts unexpectedly.
The installation of this patch fixes this issue. This patch also fixes openit_server binary for not
being able to send files with different encoding (eg. UTF-16).
