Doc: Update Microsoft's Documentation Links

The documentation links on `msdn.microsoft.com` now redirect to
`docs.microsoft.com`.

While the redirection works, our script to catch broken links on
dev-snapshots builds of the documentation doesn't handle redirection
correctly, reporting it as broken.

Both to appease the broken-links script and to avoid an unneccesary
redirection, the links were modified to point to the equivalent address
in the new domain.

Furthermore, the link to the `Winsock 2 Socket Handle` was moved to be
an `\externalpage` link, as it was used in two different places.

Additionally, the `\externalpage` link titled `Dirext X SDK` was removed
as it was not used in any part of the documentation.
