[libvirt] [libvirt-php 2/3] Fixed some compilation warnings

[Lyre]

Eliminated some compliation warings;
Fixed "differ in signedness" warnings, It may need to be reviewed.

* src/libvirt.c: Added header "standard/info.h"; Added return statement
  for libvirt_virConnectAuthCallback(); Fixed "differ in signedness"
  by change or casting those variables to unsigned.
