Identify current CPU. This is necessary to setup
affinity registers and to provide support for

We can map these system calls directly to the FreeBSD counterparts. The
other filesystem related system calls will be sent out for review
separately, as they are a bit more complex to get right.
an if_ixv instance can now set at creation time, and the receive ring
tail pointer is correctly initialized (previously, things still worked
because the receive ring tail pointer was being fixed up as a side
effect of other activity).

I performed the commit on a different system as where I wrote the
change. After pulling in the change from Phabricator, I didn't notice
that a single chunk did not apply.

The random_get() system call works similar to getentropy()/getrandom()
on OpenBSD/Linux. It fills a buffer with random data.
This change introduces a new function, read_random_uio(), that is used
to implement read() on the random devices. We can call into this
function from within the CloudABI compatibility layer.

The first system call is used to set the user TLS address. Right now
this system call is invoked by the C library for both the initial thread
and additional threads unconditionally, but in the future we'll only
call this if the architecture does not support this. On recent x86-64
CPUs we could use the WRFSBASE instruction.
This system call was erroneously placed in sys/compat/cloudabi64, even
though it does not depend on any pointer size dependent datastructure.
Move it to the right place.

Add a routine similar to copyinuio() and freebsd32_copyinuio() that
copies in CloudABI's struct iovecs. These are then translated into
FreeBSD format and placed in a 'struct uio', so we can call into the
kern_*() functions.

Summary:
As discussed with kib@ in response to r285404, don't call into
kern_sigaction() within proc_raise() to reset the signal to the default
action before delivery. We'd better do that during image execution.
Change the code to simply use pksignal(), so we don't waste cycles on
functions like pfind() to look up the currently running process itself.
Test Plan:
This change has also been pushed into the cloudabi branch on GitHub. The
raise() tests still seem to pass.

Call arm_init_secondary before any other PIC-related functions
are called. This is necessary for GICv3 where PIC_INIT_SECONDARY
allocates resources needed for all further operations.
