tang: Add package tang into tree
Tang is lightweight server for binding data to network presence. --- Tang's source: https://github.com/latchset/tang Maintainer: @Tiboris Compile tested: (mips, TL-WR842N, 17.01.4, r3560-79f57e422d) **Tang requires a few other software libraries:** 1. libhttp-parser: 2. xinetd's socket activation 3. jose >= 8: **Compared to tang upstream:** ***Two new files:*** - tangdx : configuration file for xinetd - tangdw : wrapper for tangd service - puts timestamp when service activated, and - redirects stderr to log file in /var/log/ ***Removed systemd requirement and nagios program*** Signed-off-by: Tibor Dudlák <tdudlak@redhat.com>
