Fix for CONC-608: Replace server error codes

Since Connector/C is not able to retrieve
error strings for server error codes, the following
error codes were replaced:

- ER_NET_PACKET_TOO_LARFE by CR_NET_PACKET_TOO_LARGE
- ER_OUT_OF_RESOURCES by CR_OUT_OF_MEMORY
- ER_NET_WRITE_ERROR by CR_ERR_NET_WRITE (new constant)
- ER_NET_UNCOMPRESS_ERROR by CR_ERR_NET_UNCOMPRESS (new constant)
