libupnp 1.6 is starting to get really old and caused bugs recently with the new winpthread rework for contribs. Bumping to 1.8 provides is good enough for now as it provides a lot of fixes and removes the need for some patches applied upstream a while ago.
Removed contrib patches:
- 0001-Do-not-try[...] -> Fixed upstream by 386b7ed7
- dont_use_down_intf.patch -> Fixed upstream by 1f2e3b88
- fix_infinite_loop.patch -> Fixed upstream by 4367cbfa
- libpthread.patch -> Fixed locally in rules.mak
- missing_win32.patch -> Fixed upstream by 02bb90c5
Edited patches (mostly to fit the new sources):
- miniserver.patch
- upnp-no-debugfile.patch
- libupnp-win32.patch (Partially fixed upstream)
- libupnp-win64.patch (Partially fixed upstream by 421d5d28)
- windows-version-inet.patch
- libupnp-win32-exports.patch
- libupnp-pthread-w32-checks.patch
- use-unicode.patch
