- Remove i2c_channel_t. Now the i2c protocol ops use a uint32_t index
  to specify the i2c channel

- Remove i2c_set_bitrate() from the high level i2c protocol.
  None of our drivers actually implement this, and if they did
  this would be something set by the platform board driver,
  not the client.

- Remove the "actual" parameter from i2c_complete_cb.
  i2c read transfers either return the amount requested or fail,
  so this parameter is not needed.

- Add new protocol ZX_PROTOCOL_I2C_IMPL for i2c drivers to implement
  This is a simpler protocol to implement than the existing ZX_PROTOCOL_I2C protocol

- Convert the aml-i2c and dw-i2c drivers to implement ZX_PROTOCOL_I2C_IMPL
  instead of the higher level ZX_PROTOCOL_I2C protocol

- Move logic for queueing i2c transactions from the i2c drivers
  to the platform bus driver

This reverts commit 1229a100.

A path exists where in the LL_DEBUG case a uart puts happens before the
driver has had a chance to run its early init hook. This add a test to
make sure the driver is initialized before trying to write the string.

Use interrupt 32 as the test vector. Previously 0 was used, which is
counted as an NMI and injected into the guest before it has set up the
IDT.

Also, a slight change to interrupt injection code. Vectors 0-31 are
exceptions and so should by labeled as hardware exceptions when passed
to the guest. However, breakpoint and overflow exceptions should be
software exceptions. Previously all vectors up to the max Intel defined
vector were reported as hardware exceptions (and also considered to be NMIs),
here we lower that to only include vectors below the user defined base (32).

Remove an unnecessary assertion.

100usec is often enough that timer_set() returns before the timer has
run, but it's not always enough, in which case the EXPECT_EQ() would
fail.

Rather than increasing the wait time that we pass to timer_set(), we
can just remove this assertion, which I had originally added just to
make sure that the "while (!timer_ran)" loop works properly.

`fx mkzedboot -i` now creates zedboot keys with minfs partitions in a GPT
with the special installer type GUID and containing a binary for paving a
copy of the system from that key.

When there are many interrupts pending from devices, there may not be
any spare list registers for the timer interrupt. If the timer interrupt
isn't fired on time, Linux's RCU handling becomes unhappy. Therefore
always give preference to timer interrupts.

Under the new rules you cannot bind a path below a path
that has a remote bind point.  So, for example:

create(ns) OK
bind(ns, "/dev/foo", 1) OK
bind(ns, "/dev/bar", 2) OK
bind(ns, "/dev", 3) FAIL
bind(ns, "/tmp", 4) OK
bind(ns, "/tmp/tmp", 5) FAIL

create(ns2) OK
bind(ns2, "/", 6) OK
bind(ns2, "/tmp", 7) FAIL

And when you open something via the namespace you either get a
pure virtual directory (like "/" or "/dev" in the above example)
that you can readdir() and open_at() but cannot otherwise interact
with, or you get a clone of the bound directory ("/dev/foo, "/dev/bar",
or "/tmp" in the example) which you can pass to another process,
do all the usual directory operations on, etc.

In preparation for changing the zx_vmo_read() and write() syscalls,
introduce aliases (zx_vmo_read_old() and write_old()) for the existing
behaviour, migrate zircon callers to the aliases, and mark the original
syscalls as deprecated.

Once the garnet and above layers have been migrated, the original
syscalls will be adjusted to remove the "actual" argument, and the
temporary _old() versions will be deprecated, and then removed.
