encountered in the document and some source files.

This change adds support for the USB Transport Layer as described
in the bluetooth spec. Isochronous endpoints are not yet supported.
Because of limitations in the NuttX bluetooth stack, only one USB
device can be used. This driver will only allow one USB dongle to
use bluetooth.
A Laird USB BT4.2 dongle (from Mouser) was used for testing:
M/N BT851 1.0 1829, FCC ID:SQGBT850
lsusb: 04b4:f901 Cypress Semiconductor Corp. CYW20704A2
The following commands were used to test from the nsh prompt:
bt bnep0 scan start
bt bnep0 scan stop
bt bnep0 scan get
bt bnep0 info
The Linux gatttool was used to connect over wireless.
With the BDAddr found by "bt bnep0 info", start gatttool using:
gatttool -b BDAddr -I
Connect to the device using:
connect
Read the device name using the GAP device name UUID:
char-read-uuid 2a00
Part of the response is:
value: 41 70 61 63 68 65 20 4e 75 74 74 58
which is the string "Apache NuttX"
1. Update all CMakeLists.txt to adapt to new layout
2. Fix cmake build break
3. Update all new file license
4. Fully compatible with current compilation environment(use configure.sh or cmake as you choose)
------------------
How to test
From within nuttx/. Configure:
cmake -B build -DBOARD_CONFIG=sim/nsh -GNinja
cmake -B build -DBOARD_CONFIG=sim:nsh -GNinja
cmake -B build -DBOARD_CONFIG=sabre-6quad/smp -GNinja
cmake -B build -DBOARD_CONFIG=lm3s6965-ek/qemu-flat -GNinja
(or full path in custom board) :
cmake -B build -DBOARD_CONFIG=$PWD/boards/sim/sim/sim/configs/nsh -GNinja
This uses ninja generator (install with sudo apt install ninja-build). To build:
$ cmake --build build
menuconfig:
$ cmake --build build -t menuconfig
--------------------------
2. cmake/build: reformat the cmake style by cmake-format
https://github.com/cheshirekow/cmake_format
$ pip install cmakelang
$ for i in `find -name CMakeLists.txt`;do cmake-format $i -o $i;done
$ for i in `find -name *\.cmake`;do cmake-format $i -o $i;done

USB drivers should not try control devices in the usbhost_disconnected
function. The control endpoint is NULL at this point because the device
has already been disconnected.
Before this change, the hub driver crashed when the child called
usbhost_hubpwr after the parent had already deactivated the control
pipe and set hport->ep0 to NULL.
An off-by-one error caused invalid memory to be accessed when the
last port was used. The first entry, at index 0, was never used.
The USB standard uses 1-based numbering for hub ports. This number
was used to index an array. This change converts the port number to
a zero-based port index when the array is accessed. The zero-based
value in the port field of the usbhost_hubport_s structure is also
converted before printing.
For testing, this bug was exposed on a 4 port hub when port 4 was
used after changing USBHUB_MAX_PORTS to 4 in hub.h. The bug should
also be triggered without changing hub.h if a 7 port hub is
available.
Devices connected to the same USB bus should have unique function addresses.
This was not true for root hubs with multiple ports. After this change,
enumeration is more reliable on the sama5d3-xplained board when both root hub
ports are used.
This change amounts to using one usbhost_devaddr_s object per root hub
instead of one per root hub port. For the majority of boards only one
root hub port is available so no change in behavior should be expected.
Using the interrupt pipe is recommended in the Get_Report
request section of the HID standard. This option has been
added to support some keyboards that refuse to return valid
keys when polled using the Get_Report request. Support for
the Caps Lock key, including LED, has also been added.
Choose a divider value that matches the description provided within
the same header file.
Include stddef.h to fix compiler errors because NULL is not defined.
Make logs print protocol, vid and pid consistently, (decimal hex hex).
since mmap may exist in block_operations, but truncate may not,
moving mmap beforee truncate could make three struct more compatible

- Add mmap into file_operations and remove it from ioctl definitions.
- Add mm_map structure definitions to support future unmapping
- Modify all drivers to initialize the operations struct accordingly

In the past, header file paths were generated by the incdir command
Now they are generated by concatenating environment variables
In this way, when executing makefile, no shell command will be executed,
it will improve the speed of executing makfile
