[ULOGD PATCH 2/5] Factorize definition of some macros.

[Eric Leblond <eric@inl.fr>]

Some macros were defined several time. This was the case of GET_VALUE,
pp_is_valid. This patch puts the definition in ulogd.h and fixes the
definition of pp_is_valid which was wrong (causing segfault by acessing to
fields at NULL).
