[PATCH] Command line option for pid+timestamp in OOS-log filename

[elexis]

If you try to reproduce an out-of-sync error, host a game with one instance, join as a client with the second instance of 0ad and actually manage to produce an out of sync error, then both instances of 0ad will write the ooslog to the same file. Thus one file will be overwritten and you can't diff the files.

attachment:t3255_use_timestamp_and_pid_for_oosdump_filename.patch:ticket:3255​ contains a patch that adds the current unix timestamp and process id to the filename and thereby prevents the file from being overwritten.

However since oos dumps are very big (dozens of megabytes) multiple files should only be created if the application was started with a specific command line argument.

Adds the command line switch, updates readme.txt. Add true || to the cit->second != expected check in line 647 of NetTurnManager to trigger an out of sync error, even as the only client on a server.

Changed the name of the option to "oosdump-unique", some beautifying.

Uses std::time(NULL) instead of std::time(0).
