Google is working to change its source code to use more inclusive
language. To that end, replace the term "dummy" with inclusive
alternatives.
BUG=b:162781382
BRANCH=None
TEST=make -j buildall
`grep -ir dummy *`
The only results are in "private/nordic_keyboard/sdk8.0.0"
which is not our code.

run_test is called by the "runtest" console command. Console commands
can take arguments, so pass along the arguments to run_test to allow
parameters to be passed to run_test.
The following command was used for automatic replacement:
git grep --name-only 'void run_test(void)' |\
xargs sed -i 's#void run_test(void)#void run_test(int argc, char **argv)##'

This is done via:
* queue_begin(q) gets an iterator to the start of the list
* queue_next(q, &it) updates the iterator to the next element
** Once the iterator reaches the end, ptr will be NULL.
** If the queue was modified between the _begin and _next calls
queue_next will terminate the iterator (set the ptr to NULL).

This change updates the queue_get_write_chunk and
queue_get_read_chunk logic to return an updated queue_chunk.
The new chunk uses a void * for the buffer and replaces length
with count. This more tightly aligns to how the rest of the
queue functions operate. Further, it adds the ability to
offset the write chunk. This is important as it allows wrapping.
For example:
With a queue of 8 units, 1 byte each. Assume H=2, T=5. Previously,
we were only able to ever get the 3 bytes at 5-7. Using the offset
of 3 though, we can now also get the 2 byte write chunk 0-1.

Previously all access to the queue was done by adding or removing units
with no access to the underlying byte array, or ability to notify the
queue that the byte array had been updated. This prevented direct DMA
transfers to and from the underlying byte array.
This change adds a new struct, a queue_chunk, that represents a
contiguous region of the queues byte array. Regions of valid units as
well as free space can be requested. And there are now update functions
to signal to the queue that new units were added or existing units were
read from these chunks. A chunk can be queried and used to initialize
a DMA transfer, as interrupts or polling indicates that the DMA is
working the queue indicies can be updated and the policy activated as
needed.

Previously there was no way to remove multiple units at a time
from the queue, and the queue was wasting an entry to disambiguate
full from empty. There was also no way to get the free entry
count from the queue, only the ability to query if it was above
a required amount. The queue was also storing its constant
compile time configuration as well as its dynamic state in the
same structure. This wasted RAM on configuration information
that doesn't change.
This refactor fixes these issues, making the queue suitable for
use in the new USART stream driver.
