[libvirt] [snmp PATCH 10/20] src: Fix includes in header files

[Michal Privoznik]

A header file should include another header file if and only if
an there exists a symbol that requires the inclusion. For
instance, if a header file declares the following function:

  int function(virDomainPtr dom);

then it is okay to have the header file include libvirt.h.
Unfortunately, some of our header files have needless includes.
