/**
PN_HANDLE is a trick to define a unique identifier by using the address of a static variable.
You MUST NOT use it in a .h file, since it must be defined uniquely in one compilation unit.
Your .h file can provide access to the handle (if needed) via a function. For example:
/// my_thing.h
pn_handle_t get_my_thing(void);
/// my_thing.c
PN_HANDLE(MY_THING);
pn_handle_t get_my_thing(void) { return MY_THING; }
Note that the name "MY_THING" is not exported and is not required to be
unique except in the .c file. The linker will guarantee that the *address* of
MY_THING, as returned by get_my_thing() *is* unique across the entire linked
executable.
