From: Taimoor Mirza <tmi...@codesourcery.com>
port redirection code uses SO_REUSEADDR socket option before binding to
host port. Behavior of SO_REUSEADDR is different on Windows and Linux.
Relaunching QEMU with same host and guest port redirection values on Linux
throws error but on Windows it does not throw any error.
Problem is discussed in
http://lists.gnu.org/archive/html/qemu-devel/2013-04/msg03089.html

Changes in v3:
- Removed extra commit
Changes in v2:
- Changed #ifdef to #ifndef as SO_REUSEADDR should not be set in case of
Windows.
