d77f6693e4 Make printnum_* functions return boolean status 
With this change, printnum_* functions return true iff they
successfully fetched necessary data from tracee's memory.

printnum_long_int, printpair_int, printpair_int64): Return bool.
* util.c (DEF_PRINTNUM, DEF_PRINTPAIR, printnum_long_int): Likewise.

383386de73 net.c: recvfrom fixes 
This change fixes these three problems (before/after is shown):

On interrupted syscall, flags are not decoded:

    -recvfrom(3, 0x7fff0a41e306, 10, 2, 0, 0) = ? ERESTARTSYS
    +recvfrom(3, 0x7fff0a41e306, 10, MSG_PEEK, 0, 0) = ? ERESTARTSYS

If peer address is unavalable (example: anon sockets from socketpair()),
kernel returns socklen of 0, but we ignore that and show bogus sockaddr data:

    -recvfrom(3, "123456789\0", 10, MSG_PEEK, {sa_family=0x7777 /* AF_??? */, sa_data="wwwwwwwwwwwwww"}, [0]) = 10
    +recvfrom(3, "123456789\0", 10, MSG_PEEK, 0x7ffde6edf760, [0]) = 10

SYS_FUNC(recvfrom) passes address of fromlen, not fromlen, to printsock():

    -               printsock(tcp, tcp->u_arg[4], tcp->u_arg[5]);
    +               printsock(tcp, tcp->u_arg[4], fromlen);
