First set of uncompiled and untested header files
Logging macros; tested code.
CC_LOG_ERROR will abort the program. Use with caution. For most errors, use CRITICAL level.

Example:
main(int argc, char **argv)
{

    if((argc == 2) && (!g_strcmp0("-v", argv[1]))) {
        CC_LOG_ENABLE_DEBUGS();
    }

    CC_LOG_WARNING("%s(%d): Warning 1", __FUNCTION__, __LINE__);
    CC_LOG_DEBUG("%s(%d): Debug 2", __FUNCTION__, __LINE__);
    CC_LOG_CRITICAL("%s(%d): Critical 3", __FUNCTION__, __LINE__);
    CC_LOG_INFO("%s(%d): Info 4", __FUNCTION__, __LINE__);
    CC_LOG_ERROR("%s(%d): Error 5", __FUNCTION__, __LINE__);

    return 0;
}

Output:
eusjgala176:test edeedhu$ ./test

Cleaned up design and updated header files
Fixed a bug
Final high level design for review
Merge pull request #2 from edeedhu/dev-onf-driver

Commit Zero.
Design TBD: 
1. concurrent server model for threads
2. openflow version negotiation in the of-aware layer
3. connection retries with graceful backoff in the of-aware layer
Modified cc_of_global.h
  * a struct was defined twice. fixed it.
  * introduced the tracking of poll threads.

Added new files
  * a .h and .c for poll thread management

TBD
  * additional comments in the poll thread manager .h/.c files
  * additional #includes in poll thread manager .h file for compiling
Merge pull request #3 from edeedhu/dev-onf-driver

poll thread manager code and some changes to the global structure
