Copying Module.symvers is the oldest supported method for building external
kernel modules that depend on another external kernel module. Since support
for that method will be removed from Linux kernel v5.5, use
KBUILD_EXTRA_SYMBOLS instead to specify the external symbols SCST kernel
modules depend on. Support for KBUILD_EXTRA_SYMBOLS was introduced in
upstream kernel v2.6.26 so this patch drops support for kernels before
v2.6.26.

This patch adds support for kernel module namespaces. This patch is essential
when using SCST in combination with kernel version v5.4 or later.

Instead of only checking the mlnx-ofed-kernel-dkms, also check the
mlnx-ofed-kernel-modules package name.

This patch fixes the following Coverity complaint:
7. assignment: Assigning: usn_len = max_len. The value of usn_len is now 252.
CID 326814 (#1 of 1): Out-of-bounds access (OVERRUN)
8. overrun-buffer-arg: Overrunning array virt_dev->usn of 21 bytes by
passing it to a function which accesses it at byte offset 251 using
argument usn_len (which evaluates to 252).
Fixes: ca180efeec ("scst_vdisk: Avoid that vdisk_usn_vpd() can trigger a buffer overflow")

Use lockdep_register_key() and lockdep_unregister_key() instead of
disabling lockdep checking for certain lock objects. See also Linux
kernel commit 108c14858b9e ("locking/lockdep: Add support for dynamic
keys"; kernel version v5.1).

Remove this debug assert because it a write residual can happen, e.g. if the
expected transfer length exceeds the Data Out buffer length. This statement
was hit by the following CDB, submitted by the libiscsi regression tests:
