Seed7

The type 'pollData' and several functions were added to the "socket.s7i" library. The makefile "mk_djgpp.mak" was improved to use 'djecho'. The library "duration.s7i" was improved to support the operators +:= and -:= for the type 'duration'. The function 'startProcess' in the library "shell.s7i" was overloaded. The function 'socWrite' in "soc_rtl.c" was improved. The interpreter, compiler, and runtime library (new files "pollib.c", "pollib.h", "pol_sel.c", "pol_unx.c", and "pol_drv.h") were improved to support 'pollData'. The "ftpserv.sd7" example program was improved to work silently.
