[Opendnssec-develop] New conf.xml options in 1.3.18 and 1.4.6

[Matthijs Mekking]

Hi,

FYI: This pull request for 1.3.18:

	https://github.com/opendnssec/opendnssec/pull/89

introduces three new optional elements for conf.xml:

//Configuration/Enforcer/PidFile
//Configuration/Signer/PidFile
//Configuration/Signer/SocketFile

This required changes in ods-control, namely a way to read out the value
out of the conf.xml instead of using the default. It seems the most
simple to create a new tool: ods-getconf, that can read out
the value, given an expression.

I would also like to apply this to 1.4.6.

Best regards,
  Matthijs
