Don't rely on nonstandard bsd_signal() function, instead require that the platform has sigaction(). This is 2001, after all. This may resolve some potential portability problems. Log a message if memory allocation fails, instead of dying silently. Clean up the main dispatch loop. Use <sysexits.h> for exit codes, if it exists. Reformat tftpd.c to match the other files.
