Merge remote-tracking branch 'sweil/mingw' into staging
# By Sebastian Ottlik
# Via Stefan Weil
* sweil/mingw:
util: call socket_set_fast_reuse instead of setting SO_REUSEADDR
slirp: call socket_set_fast_reuse instead of setting SO_REUSEADDR
net: call socket_set_fast_reuse instead of setting SO_REUSEADDR
gdbstub: call socket_set_fast_reuse instead of setting SO_REUSEADDR
util: add socket_set_fast_reuse function which will replace setting SO_REUSEADDR
