[ Upstream commit 77be4c878c72e411ad22af96b6f81dd45c26450a ]
Indeed musl doesn't define old SIGCLD signal name but only new one SIGCHLD.
SIGCHLD is the new POSIX name for that signal so it doesn't change
anything on other libcs.
This fixes this kind of build error:
usbipd.c: In function ‘set_signal’:
usbipd.c:459:12: error: 'SIGCLD' undeclared (first use in this function)
sigaction(SIGCLD, &act, NULL);
^~~~~~
usbipd.c:459:12: note: each undeclared identifier is reported only once
for each function it appears in
Makefile:407: recipe for target 'usbipd.o' failed
make[3]: *** [usbipd.o] Error 1

This patch removes checking of socket descriptor value in daemons.
It was checked to be less than FD_SETSIZE(1024 usually) but it's not
correct.
To be exact, the maximum value of descriptor comes from
rlimit(RLIMIT_NOFILE).
Following kernel code determines the value :
get_unused_fd_flags() : fs/files.c
__alloc_fd() : fs/files.c
expand_files() : fs/files.c
The defalut (soft limit) is defines as INR_OPEN_CUR(1024) in
include/linux/fs.h which is referenced form INIT_RLIMS in
include/asm-generic/resource.h. The value may be modified with ulimt,
sysctl, security configuration and etc.
With the kernel code above, when socket() system call returns positive
value, the value must be within rlimit(RLIMIT_NOFILE). No extra
checking is needed when socket() returns positive.
Without 'usbip: vhci number of ports extension' patch set, there's no
practical problem because of number of USB port restriction. With the
patch set, the value of socket descriptor can exceed FD_SETSIZE(1024
usually) if the rlimit is changed.

Extract the code from current stub driver backend and a common
interface for both stub driver and vudc. This allows to share most
of the usbipd code for both of them.

Delete a local structure that is only used to be initialized by memset.
A semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>

identifier x,i;

{
... when any
-struct i x;
<+... when != x
- memset(&x,...);

}

and can be moved out of staging.
