"""core/glib: poprawne sumy + wirtualna nazwa glib2.

Stan wyjsciowy: 3 zrodla, ale 4 wpisy sha256sums (wszystkie SKIP) - nadmiarowy
wpis + brak jakiejkolwiek weryfikacji pobieranych zrodel.

Zmiany:
  1. sha256sums = 3 oficjalne sumy w kolejnosci source (glib/GI z
     download.gnome.org *.sha256sum, patch policzony lokalnie),
  2. provides: [glib2] - konwencja Arch/NuTyX; w repo pakiet nazywa sie `glib`
     (103 receptury), a czesc receptur (np. libgsystemservice) wola `glib2`,
  3. pkgrel 1 -> 2.
