devel/lfcbase: update 1.10.2 -> 1.10.3

• Value change of NetHandler::SENDLEN from 1024 to 8192 On FreeBSD based systems, the lower value lead to a poor network performance for large mesages, since subsequent send calls seem to slow down the network throughput. On OSX and Windows/MinGW64 based systems, this effect has not been observed but a sendlen of 8192 seems to be no problem also for these systems
