For the general case, pragma once is better replacement for of include
guards. One line instead of three, less scopes to close in the end of
the file, no chance to having the outdated names in the define symbol.
Remove unnecessary includes, reorder them in blocks separated by a blank
line
- Corresponding header file (if exists)
- System headers
- Other ArduPilot library headers
- "Local" headers (from the same library)
Now that SITL is compiled only when it's needed (i.e. using the SITL
board), there's no need to ifdef its files based on the
CONFIG_HAL_BOARD. So remove them.
This commit changes the way libraries headers are included in source files:
- If the header is in the same directory the source belongs to, so the
notation '#include ""' is used with the path relative to the directory
containing the source.
- If the header is outside the directory containing the source, then we use
the notation '#include <>' with the path relative to libraries folder.
Some of the advantages of such approach:
- Only one search path for libraries headers.
- OSs like Windows may have a better lookup time.
