Fix warnings

Warnings came up using MinGW 4.4:
* botan.cpp: integer constant is too large for 'long' type
* dnssd_clientlib.c, dnssd_clientstub.c: ignoring #pragma warning
* hostutils.cpp: comparison between signed and unsigned integer expressions
* qmakebuildins.cpp: 'QString windowsErrorCode()' defined but not used
