linux-user: Add strace support for a group of syscalls
This patch implements strace argument printing functionality for following syscalls:
*acct - switch process accounting on or off
int acct(const char *filename)
man page: https://www.man7.org/linux/man-pages/man2/acct.2.html
*fsync, fdatasync - synchronize a file's in-core state with storage device
int fsync(int fd)
int fdatasync(int fd)
man page: https://www.man7.org/linux/man-pages/man2/fsync.2.html
*listen - listen for connections on a socket
int listen(int sockfd, int backlog)
man page: https://www.man7.org/linux/man-pages/man2/listen.2.html
Implementation notes:
Syscall acct() takes string as its only argument and thus a separate
print function "print_acct" is stated in file "strace.list". This
function is defined and implemented in "strace.c" by using an
existing function used to print string arguments: "print_string()".
All the other syscalls have only primitive argument types, so the
rest of the implementation was handled by stating an appropriate
printing format in file "strace.list".
