New SITL AP_Periph board modelled on the ChibiOS PPPGW boards (eg
Pixhawk6X-PPPGW), with the PPP networking backend, scripting, and a
ROMFS-embedded copy of the pppgw_webui.lua web interface from
Tools/AP_Periph/Web. Intended for end-to-end PPP testing between two
ArduPilot SITL processes and for exercising the PPPGW web server in
SITL.
The hwdef:
- enables AP_PERIPH_NETWORKING_ENABLED, AP_NETWORKING_BACKEND_PPP and
AP_NETWORKING_CAN_MCAST_ENABLED;
- points NET_PPP_PORT at serial 1 so the periph can be wired to the
plane SITL via --serial1=tcpclient:127.0.0.1:<port>;
- enables AP_SCRIPTING + AP_FILESYSTEM_ROMFS + AP_PARAM_DYNAMIC, and
embeds Tools/AP_Periph/Web/ via ROMFS_DIRECTORY;
- disables Lua bindings whose backing libraries AP_Periph does not link
(AP_Vehicle/AC_Fence/AP_Button/AP_Camera/AP_Mount/AP_OpticalFlow/
AP_VisualOdom/AP_Frsky_Telem/AP_Arming/RC_Channel). ChibiOS periph
builds handle this via defaults_periph.h; SITL periph has no
equivalent so we list the gates inline.
ROMFS support for SITL hwdefs (the ROMFS / ROMFS_WILDCARD /
ROMFS_DIRECTORY keywords) is added to sitl_hwdef.py, modelled on the
ChibiOS hwdef parser. Files are published via env_vars['ROMFS_FILES']
and picked up by the existing waf embed_ROMFS_files step in boards.py.
A new sitl_periph_PPP-specific defaults file
(Tools/autotest/default_params/periph-ppp.parm) holds runtime overrides
that should always apply to this build: NET_PPP_BAUD=921600 (saner
than the 12.5Mbaud real-hardware default for the loopback-TCP
transport), and SCR_ENABLE=1 so the web interface script comes up at
boot.

e.g.
./Tools/scripts/param_check_all.py:180:40: B008 Do not perform function calls in argument defaults. The call is performed only once at function definition time. All calls to your function will reuse the result of that definition-time function call. If this is intended, assign the function call to a module-level variable and use that variable as a default value.
