[libvirt] [PATCHv2 1/3] build: update gnulib for pipe on mingw

[Eric Blake]

* .gnulib: Update to latest.
* bootstrap.conf (gnulib_modules): Import pipe-posix for mingw.
* src/remote/remote_driver.c (pipe) [WIN32]: Drop dead macro.
* daemon/event.c (pipe) [WIN32]: Drop dead function.
---

v2: also fix daemon, and add two more patches that allow
./autobuild.sh to once again pass a mingw cross-build.
