The sslget tool sends a TLS SNI header. Apache doesn't like server name
indication without a matching HTTP header. Requests without a Host
header are refused with

HTTP/1.1 400 Bad Request
Hostname example.org provided via SNI, but no hostname provided in HTTP request

sslget now sets a Host HTTP header for all requests.

(cherry picked from commit 73f5e33c945d865a88b47491b73553ba8ecf2f53)

In both sslget.c and revoker.c there is an incorrect equality
check which compares the output of a comparision operator with
a constant(SECFailure) which has a value of -1. The fix will print
the correct SECFailure or SECSuccess value for the do_writes method.

* Bugzilla Bug #953464 - ipa-server-install crashes due to sslget error
* Bugzilla Bug #859043 - ipa-server-install results in error -5987

* Added RESTful servlet to add/remove a KRA connector from the CA.
* Modified ACL to allow KRA subsystem user to remove connector.
* Modified connector code to allow the connector to be replaced without a server restart.
* Added functionality to pki CLI to add/remove connector
* Added code to pkidestroy to remove the connector (using both pki CLI and sslget)
  When the issues with pki connection are resolved, we will use that method instead.
* Modified sslget to accept HTTP return codes != 200.  In this case, we were returning
  204 - which is perfectly legitimate.

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.
