Changes in Dad 1.20 since 1.10

• A new function dadMulMsg which allows to wait for information on multiple sockets.
• Another new function dadRepUpdate to overwrite old information with timestamps in a given period of time.
• Two functions dadNextUpdate and dadPrevUpdate which return time information at which the current updated dataflow looses validity.
• dadWUpdate is now documented to set the iTimeEnd flag to TIM_TILLEVER.
• Servers now use 3 files for running. This is the real RZ file, a backup of the state at server startup and a journal file which a server can use to recover from backup. Suppose the RZ file connected to a served dataflow. This means a server crash does no longer mean loss of data!
• Stale unix sockets are detected at startup and automaticly removed.

• A bugfix in dadInit which could not read in the k flag for keytable access, introduced in Version 1.10. Also empty lines are now allowed in dadinit.cnf.
• A bugfix in dadAcceptSelect which crashed the server.
• Removed asserts from the server code to let a server stay alive even if the client sends garbage.
• CAC_GENTABLES can now be used even if the table exists already. A projection is generated if needed.
• Various checks on the servers ddl are performed at startup time to prevent at least some of the possible user errors.
• Fixed a severe bug that crashed the client if CAC_KEYTABLE was used. Thanx to Machiel.
