QAbstractSocket: fix setReadBufferSize from readyRead slot.

In a slot connected to readyRead, if the app detects that the
buffer size is too small and increases it, it expects that
readyRead() will be emitted again.

setReadBufferSize() doesn't re-enable the socket notifier when
calling from within readyRead, and readyRead itself was missing
the code to do it.

Minor optimization

Querying the "extra" fallback fonts (which are hard-coded names, actually)
for family only makes sense for scripts that cover more than just a single WS;
these currently are Common (<-Inherited) and Han.

apply WinRT store certification linker flags

Those flags are required to pass the Windows Store App Certification
process. Otherwise apps are not allowed to be published.

The SAFESEH option is only required for x86.

According to documentation APPCONTAINER only talks about the
executable, but when running through the certification, the Qt modules
are reported to be errornous as well.
