add egd-management

We can now run hosts with a key in the host mode, so it will
provide entropy to other hosts. Furthermore we can define clients
that will collect entropy from such a host.

+
+-- Only one output mode is permitted to be active. Typically on Linux
+-- that would be the kernel output mode, however instead you can opt
+-- to use the EGD interface. Various other daemons then support taking
+-- EGD interfaces and adding entropy to the kernel instead, allowing
+-- multiple clients to retrieve entropy by various means.
+
+-- The SetOutputToKernel option places all the gathered entropy into
+-- the kernel pool. The data placed into the kernel pool is
+-- conservatively estimated to contain 7 shannons of entropy per byte
+-- added.
+-- Note that the data coming from the UDEKEY01 should have one Shannon
+-- of entropy per bit so this value could quite safely be set to
+-- 8. The default value only has the effect of reducing the rate
+-- entropy is mixed into the kernel pool and no other adverse
+-- affect. This default is selected as an conservative choice which is

+-- protocol. There are two choice to create either a TCP or Unix
+-- socket which speaks the EGD protocol.
+-- Note that you cannot have kernel output *and* EGD output, they are
+-- mutually exclusive.
+-- The EGD protocol support assumes entropy coming off the ekeys is at
+-- the level of 8 shannons per byte and this cannot be changed as it
+-- is a limitation of the EGD protocol itself.  The TCP socket can be
+-- given an optional parameter to specify the IP address to bind to.
+-- It will default to 127.0.0.1 if not specified.
+
+-- EGDTCPSocket(8888 --[[, "127.0.0.1" ]])

+-- EGDUnixSocket can optionally take an octal mode string and
+-- username and group to chmod and chown the socket to.
+-- If you do not wish to change the user or group, use empty strings.
+-- You cannot change the user/group without also providing a mode string.
+-- The default is to leave the user/group alone and set the socket to
+-- mode 0600
+-- EGDUnixSocket("/etc/entropy", "0660", "root", "entropyusers")
+
+-- The SetOutputToFile option writes all gathered entropy to the named
+-- file. No additional processing is performed. The output file must
+-- exist before the daemon is run. This option is generally only
+-- useful if the user wishes to gather data for subsequent testing.
