Use of SAPI_CLIENT macro in socket TCTI

[flihp]

We currently compile the sockets TCTI directly into the resourcemgr on account of our use of the SAPI_CLIENT macro. We use some wrapper functions specific to the resourcemgr and use the macros to set up these function pointers. This is a bit messy and it may be better to pass these function pointers in to the TCTI through the initialization method.

I've worked out one issue with this flag in the socket TCTI by getting the resourcemgr and the test programs to use the same debug print function. Other issues remain but some progress has been made.
