Windows: manually check if we can bind on the configured port/ports
Windows allows the coexistence of three types of sockets on the same
transport-layer service port, for example, 127.0.0.1:8080, [::1]:8080
and [::ffff:0.0.0.0]:8080

Go don't properly handles this, so we use a ugly hack

Fixes #350

Use new methods in the io and os packages instead of ioutil ones
ioutil is deprecated in Go 1.16 and SFTPGo is an application, not
a library, we have no reason to keep compatibility with old Go
versions.

Go 1.16 fix some cifs related issues too.

fix a potential race condition for pre-login and ext auth
hooks

doing something like this:

err = provider.updateUser(u)
...
return provider.userExists(username)

could be racy if another update happen before

provider.userExists(username)

also pass a pointer to updateUser so if the user is modified inside
"validateUser" we can just return the modified user without do a new
query
