[PATCH v2 0/3] windows: allow building without NO_UNIX_SOCKETS

Eventhough NO_UNIX_SOCKETS was specifically added to support Windows, it might not be necessary in the future, because Windows added support for Unix Sockets in late 2017.

The implementation of Unix Sockets, uses an internal NTFS mechanism and is therefore not visible at the filesystem layer, like it is in UNIX, but seems to be good enough to allow to build and run the `git credential-cache` and its daemon; additional testing to confirm trace2 (builds and doesn't fail any tests) is functional will be needed.

V2 reuses the same third patch from V1, and applies all suggested feedback on patches 1 and 2 and should apply cleanly as a reroll of cb/unix-sockets-with-windows.

Carlo Marcelo Arenas Belón (3):
  t0301: fixes for windows compatibility
  credential-cache: check for windows specific errors
  git-compat-util: include declaration for unix sockets
