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.

Adding names database to port command.
BEFORE) 'unknown' for vendor and product string.
Imported USB devices
====================
Port 00: <Port in Use> at Low Speed(1.5Mbps)
unknown vendor : unknown product (03f0:0224)
3-1 -> usbip://10.0.2.15:3240/5-1
-> remote bus/dev 005/002
AFTER) Most vendor string will be converted.
Imported USB devices
====================
Port 00: <Port in Use> at Low Speed(1.5Mbps)
Hewlett-Packard : unknown product (03f0:0224)
3-1 -> usbip://10.0.2.15:3240/5-1
-> remote bus/dev 005/002

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.

Instead of calling strlen on every iteration of the for loop, just call it
once and cache the result in a temporary local variable which will be used
in the for loop instead.

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,...);

}

At this point, USB/IP userspace code is fully functional
and can be moved out of staging.
