source file into account. This allows quoted includes to stand out more when
the location of the source file actually is relevant.
- Use include guards to avoid the problem of double inclusion. The header file
`foo/bar.h` should use the include guard identifier `BITCOIN_FOO_BAR_H`, e.g.
```c++
#ifndef BITCOIN_FOO_BAR_H
#define BITCOIN_FOO_BAR_H
...
#endif // BITCOIN_FOO_BAR_H
