[FreeBSD and OpenBSD contributors clarified that O_CLOEXEC has been
supported for ~ 2 years on both, so for the moment we're assuming
that every platform with kqueue also has working O_CLOEXEC. Please reopen
the bug, with a tested patch that uses _dbus_fd_set_close_on_exec() instead,
if this assumption turns out to be false. -smcv]

There are memory blocks leak when doing bus-test, both dispatch-sha1 and
dispatch test cases complain memory blocks leak.
This patch also fix fd leaks.

Similar to the previous commit, almost every use of DBusWatch can just
have the main loop call dbus_watch_handle.
The one exception is the bus activation code; it's had a comment
explaining why it's wrong since 2003. We should fix that one day, but for
now, just migrate it to a new _dbus_loop_add_watch_full which preserves
the second-layer callback.

This should mean we don't get invalid fds in the main loop.
The BSD (kqueue) and Windows code paths are untested, but follow the same
patterns as the tested Linux/generic Unix versions.
DBusTransportSocket was already OK (it called free_watches() before
_dbus_close_socket, and that did the remove, invalidate, unref dance).

num_fds is the number of elements of dirs currently in use. This bug
meant that encountering a previously un-watched directory would cause j
to increment forever, and so dirs[j] would eventually segfault.
(I've checked the corresponding code for inotify, and it's correct. I
wonder if some of the duplication could be eliminated.)
Thanks to Pablo Martà Gamboa <pmarti@warp.es> for reporting this issue!

It's not expected to have to manually SIGHUP the bus after installing
a new .service file. Since our directory monitoring is already set
up to queue a full reload which includes service activation, simply
monitor the servicedirs too.

Substantially based on a patch by Matthias Clasen <mclasen@redhat.com>
kqueue implementation by Joe Marcus Clarke <marcus@freebsd.org>
Previously, when we detected a configuration change (which included
the set of config directories to monitor for changes), we would
simply drop all watches, then readd them.
The problem with this is that it introduced a race condition where
we might not be watching one of the config directories for changes.
Rather than dropping and readding, change the OS-dependent monitoring
API to simply take a new set of directories to monitor. Implicit
in this is that the OS-specific layer needs to keep track of the
previously monitored set.

* dbus/dbus-sysdeps.c (_dbus_set_errno_to_zero)
(_dbus_get_is_errno_nonzero, _dbus_get_is_errno_eintr)
(_dbus_strerror_from_errno): family of functions to abstract
errno, though these are somewhat bogus (really we should make our
socket wrappers not use errno probably - the issue is that any
usage of errno that isn't socket-related probably is not
cross-platform, so should either be in a unix-only file that can
use errno directly, or is a bug - these general errno wrappers
hide issues of this nature in non-socket code, while
socket-specific API changes would not since sockets are allowed
cross-platform)

while the other modules ignore the parameter. This allows us to
avoid platform conditionals
