[trivial PATCH 01/22] [libradius.h] eliminate build warnings

[Wang Tinggong]

hi, this is a series of trivial patch for eliminating build warnings.

this series doesn't solve warning "discards qualifiers from XXX type" , caused
by assignments between CONST and non-CONST, such operation is deprecated by C99.

if this make noises, plz forgive me.

thanks!
Tinggong
