1. Reorder http.conf to actually read worker config
2. Change functions so that the TPS would restart.  Before restarts
   would fail because the tus link already exists
3. Modify system verification test to return correctly when tests
   are successful

TPS ECC: when TPS server acts as an ECC SSL client to CA, TKS, or DRM, it needs to support ECC ciphers

ECC support for tpsclient
two parameters are added in the config file (see enroll.tps.ec for example): slotnamefile - this points to a file that contains the slot name. The reason why the slot name goes into another file instead of the conf file is because the existing conf file uses spaces for deliminator and I don't want to change the usage (and QE's tests) by changing it to something else. tokpasswod is the tokebn password

This ECC feature requires the up-coming ECC supporting TPS to trigger. Testing of the ECC specific areas requires the availability of such ECC TPS. Without it, one can test with the old RSA method to see if it's broken.

The API changed between httpd 2.2 and 2.4.  We now need to pass
the module index to ap_log_error() when calling it.  The remote_ip
member of the connection struct also was renamed to client_ip.

Previously the source code was located inside a pki folder.
This folder was created during svn migration and is no longer
needed. This folder has now been removed and the contents have
been moved up one level.
