Updating micro kernel functions to follow a consistent naming convention.
Part of that process is the removal of camelCase naming conventions for the
preferred_underscore_method. This specific change maps the macro to the
function naming used by the OS.
Change accomplished with the following script:
#!/bin/bash
echo "Searching for ${1} to replace with ${2}"
echo "Checking C, CPP, H, HPP, and s files..."
find . -type f \( -iname \*.[ch] -o -iname \*.[ch]pp -o -iname \*.s \) \
-not \( -path host/src/genIdt -prune \) \
-not \( -path host/src/gen_tables -prune \) \

Instead of having global command completion handler we can keep the
code more concise by letting bt_hci_cmd_send_sync() give back the
return parameters straight to the caller. This patch extends the
buf->hci.sync variable to not just contain the initial semaphore, but
to have the return parameter bt_buf once the semaphore is given back.
The bt_hci_cmd_send_sync() function receives an extra parameter which
may be NULL if the caller isn't interested in the return parameters.

In certain scenarios we want to keep the buffers around for longer
and avoid the default bt_buf_put() calls from putting them back to the
available buffers queue. This patch adds reference counting for the
buffers, along with a bt_buf_hold() API to increment the reference
count. Now bt_buf_put() will only put the buffer back to the pool if
the reference count hits 0.

Some logs indicate potentially problematic situations but are not
necessarily errors. Since we do want to log these regardless of the
debug setting it's better to have a separate BT_WARN macro for them.

We're already sending 'dummy' buffers to wake up the connection
fibers. The problem is that if we provide a real buffer type it may
have unintended consequences. E.g. with BT_ACL_OUT when bt_buf_put()
is called it may trigger an invalid HCI_Host_Num_Completed_Packets
command.
This patch creates a new BT_DUMMY buffer type to avoid this scenario.
The new type is an alias for BT_CMD since the pool where these buffers
come from is not quota-controlled and synced up with the controller.

Every time we put a BT_ACL_IN buffer back to the pool we should report
this to the controller so it knows it can send us more data. This
patch makes the necessary modifications to the bt_buf_put() function
to trigger the HCI command.
The Host Number of Completed Packets command is special in that it
doesn't need to obey the reported ncmd value and also doesn't generate
any command status/complete events. Because of this we need an
exception for it in the bt_hci_cmd_send() function.

In order to do proper flow control of ACL data to/from the controller
we need to have precise management of the available buffers. Mixing
with the events/commands buffers would make this impossible. This
patch splits the buffer pools into three separate ones:
1. HCI commands/events
2. Incoming ACL data
3. Outgoing ACL data
The total number of available buffers is also increased to match
what's the smallest number supported by current controllers (to avoid
the stack from becoming a bottle neck).

We may soon want to have a _wait() variant of bt_buf_get, so to avoid
the number of 'get' function growing too large consolidate the
existing get() and get_reserve() functions into a single one. The new
consolidated function also takes the type as input parameter so that
we know this from the very start and thereby plan for the split into
multiple buffer pools.

We'll soon want to have dedicated pools for outgoing and incoming ACL
data. To know from which pool to get and put the buffers each buffer
should contain enough information to distinguish the two types. This

types.

has this dependency removed, since the symbol was used for an
incomplete feature that could not be enabled. This change has
no operational impact, as the LITE symbol was never defined

In a handful of timer-related references to LITE are not removed,
as they will be useful in adding a tickless kernel capability.
