* tao/GIOP_Message_Base.h:
* tao/GIOP_Message_Generator_Parser_12.cpp:
* tao/Transport.h:
* tao/Synch_Invocation.cpp:
Strategies for resolving the POA only once for each call and
cacheing the request. The second strategy is to cache the
request header and reply header in case of single
threaded. These optimizations are using TAO_HAS_HEADER_CACHING
and TAO_CACHE_SERVANT_REF.

* tao/GIOP_Message_Base.h:
* tao/GIOP_Message_Generator_Parser_12.cpp:
* tao/Synch_Invocation.cpp:
Strategies for cacheing request headers and avoiding
re-marshaling of CORBA request header when sending remote
requests.
* tao/tao.mpc:
Added the appropriate flags TAO_HAS_NO_HEADER_REMARSHALL and
TAO_HAS_REQUEST_CACHING to the mpc file.
* tao/Strategies/SHMIOP_Connection_Handler.cpp:
* tao/Strategies/UIOP_Connection_Handler.cpp:

Spill over changes from Collocation refactoring
* tao/GIOP_Message_Base.cpp:
* tao/tao.mpc:
Prevent marshing protocol header when requests do not
change. mpc file that sets the right macro

* tao/Invocation_Adapter.cpp:
* tao/Invocation_Adapter.h:
* tao/Object.cpp:
Removed remoting code from these classes. Additionally, the
checks to determine if a reference is remote have also been
removed.
* tao/IIOP_Acceptor.h:
* tao/IIOP_Acceptor.cpp:
Factored out code for creation, acceptance and concurrency
control with the ORB core. These are removed as in collocation
mode, no remote invocations are serviced.
* tao/Connection_Handler.cpp:
* tao/Connection_Handler.h:
* tao/Connection_Handler.inl:
Factored out dependency on the transport for Connection handler
classes if two objects are collocated. The transport is not
needed as no remote requests are serviced.
* tao/IIOP_Connector.h:
* tao/IIOP_Connector.cpp:
Factored out remoting code that does opens the socket to connect
to a remote host. This functionality is not needed as objects
are collocated.
* tao/Profile_Transport_Resolver.cpp:
* tao/Profile_Transport_Resolver.h:
* tao/Transport_Cache_Manager.h:

* tao/Transport.h:
* tao/Transport.cpp:
* tao/Transport_Connector.h:
* tao/Transport_Connector.cpp:
* default_client.cpp:
* default_client.h:
Factored out functionality and state when in collocated state as
these are needed only to service remote requests.
* tao/Strategies/DIOP_Connection_Handler.h:
* tao/Strategies/DIOP_Connector.cpp:
* tao/Strategies/DIOP_Factory.h:

* tao/Strategies/SHMIOP_Connection_Handler.cpp:
* tao/Strategies/SHMIOP_Connector.cpp:
* tao/Strategies/UIOP_Connection_Handler.cpp:
* tao/Strategies/UIOP_Connector.cpp:
Factored out remoting code from the strategy classes,
particularly, transport dependecies.
* tao/Messaging/Asynch_Invocation_Adapter.cpp:
* tao/Messaging/Asynch_Invocation_Adapter.h:
If using Asynchronous communication, factored remoting code. This
includes code for invoking two way operations. This inturn calls the
Invocation Adapter's invoke which is already specialized for
collocated operation.
* tao/TAO.mpc:
Modified mpc file to add the macro TAO_HAS_COLLOCATION that
factores out remoting code. Additionally, several classes that
are not needed in this mode have been added in an excludes
directive. Eventually, this file can be generated out from a tool
based on the macro defined. Using this functionality results in a
reduction of ~90 KB in size of libTAO library and improvement of
~95% in throughput for the collocation tests
($TAO_ROOT/performance-tests/Latency/Collocation) measured on 1GHz dual
cpu box running redhat linux with 1GB of memory.
