clib_strncat
There are 3 versions of the string functions. For example, for strcpy,
they are
1. strcpy(dst, src) -- the legacy unsafe version
2. strcpy_s(dst, dmax, src) -- C11 safeC version which has an addition argument
named dmax.
3. clib_strcpy(dst,src) -- clib version to enable legacy code that uses strcpy
to make use of strcpy_s without adding the additional argument, dmax, which is
required by the C11 safeC version.
The implementation for the clib version is to artificially provide dmax to
strcpy_s. In this case, it uses 4096 which assumes that if the legacy code
works without blowing up, it is likely to work with the clib version without
problem.
gcc-11 is getting smarter by checking if dmax is within the object's boundary.
When the object is declared as static array, it will flag a warning/error
if dmax is out of bound for the object since the real size of dst can be
determined at compile time.
There is no way to find the real size of dst if the object is dynamically
allocated at compile time. For this reason, we simply can't provide support
for the clib version of the function anymore. If any code is using the clib
version, the choice is to migrate to the safeC version.

Fixes: d96b28ac0917 ("virtio: improve input node performance")
vlib_buffer_t is defined on stack to be used for input feature arc
lookup once per frame call for performance reasons. The definition
is missing the initialization to avoid the assignment of garbage value.

Originally wireguard implementation does memory copy of the whole
packet in encryption and decryption.
This patch removes unnecessary packet copy in wireguard. In addition,
it contains some performance improvement such as prefetching header
and deleting unnecessary lock and unlock for decryption.

There is no reason to enforce vnet rewrite size to be equal to pre_data.
Moreover, since vnet rewrite size is now saved as u8, this limits
pre_data to 192 bytes.

This macro privides a way to tell compiler that it is safe to assume
that specified expression is true so it can optimize code accordingly.
i.e.
CLIB_ASSUME (n < 3);
while (n)
{
/* ... */
}
Will tell compiler that n is never going to be >= 3 so instead of
creating loop it will just unroll loop 2 times.
