[v4,1/5] linux-user: Make cpu_env accessible in strace.c

Variable "cpu_env" is used in file "syscall.c" to store
the information about the cpu environment. This variable
is used because values of some syscalls can vary between
cpu architectures. This patch makes the "cpu_env" accessible
in "strace.c" so it can enable aproppriate "-strace" argument
printing for these syscalls. This will be a useful addition
for future "-strace" implementation in QEMU.

Implementation notes:

    Functions "print_syscall()" and "print_syscall_ret()" which
    are stated and defined in "qemu.h" and "strace.c" respectively
    are used to print syscall arguments before and after syscall
    execution. These functions were changed with addition of a
    new argument "void *cpu_env". Strucute "struct syscallname"
    in "strace.c" is used to store the information about syscalls.
    Fields "call" and "result" represent pointers to functions which
    are used to print syscall arguments before and after execution.
    These fields were also changed with addition of a new "void *"
    argumetn.
    Also, all defined "print_*" and "print_syscall_ret*" functions
    in "strace.c" were changed to have the new "void *cpu_env".
    This was done to not cause build errors (even though none of
    these functions use this argument).
