on macmini the compiler seems to apply the copy constructor and complain
about it.  that rather seems to be a compiler problem, but this small change
works around it.

committing it at my discretion.

- use recipient instead of forwarded as it seemed more intuitive
- descirbe how the request is responded
- use 'component' instead of 'program' where it's more appropriate
- use 'process' instead of 'program' where it's more appropriate

the formatEndpoint() function locally defined in auth_srv was essentially
moved there.  also added the test of the operator.

this will make the caller side much simpler.  in particular, the caller
now doesn't have to handle exceptions.  connect() and close() can now
be private.

To handle various types of requests, the constructor is extended to take
a message type, which will be used in the log message on failure.
log message ID and description were made generic.

so that it matches latest implementation status (and the statement is
generic and won't have to be updated this way again)

so that it doesn't necessarily mean we'll get the path from a configuration.

the latter isn't very portable.

otherwise link would fail for (e.g.) MacOS X with -no-undefined.
discussed on jabber, behavior confirmed by myself.

Asynchronous communictaion calls have been added

This is the asynchronous read on ModuleCCSession.

not really useful at this point anymore

It isn't actually used by the test, but by not setting any db, the default db would've been created (and not cleaned up, making distcheck fail for leaving files around)

As this is the better way reportedly.

for now, just like what we do for xfrout.  eventually we should get this
from the ddns configuration.

this will simplify the main code, and allow the underlying forwarder
to be hidden as private.  also, expecting we'll eventually use this for
xfrout, it will help reduce duplicate code.

MockSocketSessionForwarder was now moved to lib/util/unittests for possible
wider use.

This is to fix the ongoing problem seen on a builder:

/libexec/ld-elf.so.1: /usr/home/jreed/builder/work/BIND10-cppcheck/20120516030045-FreeBSD8-amd64-GCC/build/src/lib/datasrc/tests/.libs/run_unittests: Undefined symbol "_ZN3isc3log23checkExcessPlaceholdersEPSsj"

It was matching the library in the base system instead.

This was discussed on jabber some weeks ago.
