On a single-CPU system (booting with kernel.smp.maxcpus=1), this
reduces the number of context switches per run from 4 to 2 for the
following performance tests in zircon_benchmarks:

  RoundTrip_BasicChannel_*
  RoundTrip_ChannelPort_*
  RoundTrip_ChannelCall_*
  RoundTrip_Fidl_*

The context switch counts for the other tests are unaffected.

This change will allow some cleanup in follow-on changes: plumbing
such as kWokeThreads can be removed, because it's replaced by using
AutoReschedDisable.

In order to do this I changed the interface to allow the caller to
specify the entirety of argv. I think the benefit in testability is
worth the slight added interface complexity.

Allocate a new usb request if we don't have any matching ones in the
pool.

We now set the device as writable if there are free trbs left on the
transfer ring, rather than if we have usb requests left.

Many of these functions already have the runtime check
"DEBUG_ASSERT(spin_lock_held(&thread_lock))".  Adding a static check
using Clang lock annotations should help detect problems earlier and
should make the code more self-documenting.

The packet will no longer be in the queue when RemoveInterruptPacket()
returns, so "was_in_queue" is more appropriate.

Also, the variable can be declared in a narrower scope.

The median is useful because it's more robust against outliers than
the mean.  (On the other hand, the median is not so robust if the
running times have a multimodal distribution.)

Breaking down the fan-control thermal prototype driver
into 3 parts.

1st layer would be the Mailbox driver which would
provide communication between the two on-board
processors.

2nd layer would be the SCPI driver (System Control and
Power Interface) which would use the mailbox protocol
to set/get system configuration such as frequency/voltage
and thermal parameters.

3rd layer would be the Fan-control driver which uses
the SCPI protocol to get the temperature and controls
the fan via the GPIO protocol based on it.

(TODO): Expose the fan-ctl & SCPI interface as IOCTL's in a later CL

Main changes:
* CamelCase instead of snake_case names, in accordance with our C++
  style guide.
* Use fbl::Vector instead of list_node.
* Use fbl::MakeAutoCall and objects that clean themselves up on
  destruction instead of "goto fail".
* Potential bug fix: check if get_info() return val != ZX_OK, rather
  than previously checking if it was negative.
* Behavior improvement: insert a TestRun into the tests vector for all
  failure modes. Previously we would only do this if we got to
  launchpad_go(). There's no reason for the result to not be saved if
  the failure comes earlier than that.

If the device tree has a memory base and size, the old code would
use the size from the device tree even if the base is different than
the entry than this size will overwrite. Save and use the base address
as well. Overriding a non-zero base address with zero is not currently
supported.

ARM64 post-indexed ldr/str instructions only have a 9 bit signed reach,
unlike the regular non indexed which has a 12 bit reach. Reduce the max
stride to <256 to fix a too-long stride problem that showed up with -O0
builds.

Doesn't seem to hurt x86 builds since pretty much all strides were
calculating to <64 in all cases anyway.

Modify the setter functions for ZX_PROP_NAME to disregard data from
userspace which occurs after the trailing NUL character. Additional data
beyond NUL is garbage from userspace and shouldn't be stored in the
kernel.

Modify the getter functions to completely sanitize passed in memory
before returning it to userspace or other parts of the kernel.

Add additional tests to exercise this code and prevent regressions.
Fixup unittests (added in commit 22efc1d7) which asserts that the
buffers aren't cleared.

Fixes ZX-2048, which appears to have been introduced in commit
