* configure.ac: Add PATHSEP_C and PATHSEP_S. For W32 let all

directories default to c:/gnupg.  Require libassuan 0.6.9.

* gpg-agent.c (main) [W32]: Now that Mutexes work we can remove
the pth_init kludge.
(main): Add new options --[no-]use-standard-socket.
(check_for_running_agent): Check whether it is running on the
standard socket.

* sysutils.h [W32]: Define sleep.
* util.h: Add prototype for mkdtemp.

* call-agent.c (start_agent): Before starting a pipe server start
to connect to a server on the standard socket.  Use PATHSEP
* call-dirmngr.c (start_dirmngr): Use PATHSEP.

* import.c: Include unistd.h for dup and close.
