libxl is leaking self pipes to child processes. These can be seen when
running with env var _LIBXL_DEBUG_EXEC_FDS=1:
libxl: debug: libxl_aoutils.c:593:libxl__async_exec_start: forking to execute: /etc/xen/scripts/vif-bridge online
[Detaching after fork from child process 5099]
libxl: execing /etc/xen/scripts/vif-bridge: fd 4 is open to pipe:[46805] with flags 0
libxl: execing /etc/xen/scripts/vif-bridge: fd 13 is open to pipe:[46807] with flags 0
libxl: execing /etc/xen/scripts/vif-bridge: fd 14 is open to pipe:[46807] with flags 0
libxl: execing /etc/xen/scripts/vif-bridge: fd 19 is open to pipe:[48570] with flags 0
libxl: execing /etc/xen/scripts/vif-bridge: fd 20 is open to pipe:[48570] with flags 0
(fd 3 is also open, but the check only starts at 4 for some reason.)
For xl, this is the poller created by libxl_ctx_alloc, the poller
created by do_domain_create -> libxl__ao_create, and the self pipe for
libxl__sigchld_needed. Set CLOEXEC on the FDs so they are not leaked
into children.

Switch all usages of xs_daemon_open*() and xs_domain_open() to use
xs_open() instead. While at it switch xs_daemon_close() users to
xs_close().

Carve out all libxenlight related sources and move them to
tools/libs/light in order to use the generic library build environment.
The closely related sources for libxl-save-helper and the libxl test
environment are being moved, too.
