Building the docs (e.g. with `ninja doc`) failed with GCC (e.g. GCC 7.3
under Fedora 27) with some missing declaration errors.
Example:
../Rx/v2/examples/doxygen/main.cpp:7:13: error: no previous
declaration for ‘std::__cxx11::string get_pid()’
[-Werror=missing-declarations]
Thus, this change adds a shared declaration for `get_pid()` that is
included by all users/the file where it's defined such that
accidental deviation in the signature are immediately noticed (as
compile error).
Similarly, the visibility of the example `less()` is changed to static
as it's only locally used.
With those changes the doc target succeeds again.
