Create a new macro for static DPCPU data.
On arm64 (and possible other architectures) we are unable to use static
DPCPU data in kernel modules. This is because the compiler will generate
PC-relative accesses, however the runtime-linker expects to be able to
relocate these.
In preparation to fix this create two macros depending on if the data is
global or static.

Move some other SI_SUB_INIT_IF initializations to SI_SUB_TASKQ
Drop the EARLY_AP_STARTUP gtaskqueue code, as gtaskqueues are now
initialized before APs are started.

Add support for LinuxKPI tasklets.
Tasklets are implemented using a taskqueue and a small statemachine on
top. The additional statemachine is required to ensure all LinuxKPI
tasklets get serialized.
Add support for LinuxKPI tasklets.
Tasklets are implemented using a taskqueue and a small statemachine on
top. The additional statemachine is required to ensure all LinuxKPI
tasklets get serialized. FreeBSD taskqueues do not guarantee
serialisation of its tasks, except when there is only one worker
thread configured.
