QNX has an arbitrary limit to the number of file descriptors
which may be passed in a message, which is smaller than the
current default. This patch therefore changes the default from
a hardcoded constant to a macro, which is determined at configure
time by looking at the host operating system.
[This reduces the limit from 4096 (session)/1024 (system) to 128 fds
per message on QNX, and 1024 fds per message on other operating systems.
I think the reduced session bus limit on other OSs is a reasonable change
too, given that the default hard/soft ulimits in Linux are only 4096/1024
fds per process. -smcv]

This causes the test to fail. The assumption implicitly being made was
"if pid 1 is systemd, then every caller of _dbus_init_system_log() is a
systemd service" which is not valid for the regression test.

If DBUS_DISABLE_ASSERTS was turned on, and a buggy program called
dbus_connection_get_data() with a slot number less than zero (eg,
before even allocating the data slot), random memory would be
accessed and a random value returned. Anything less than zero
is not a valid slot number and should be rejected by libdbus.

This function is called by _dbus_read_credentials_socket() to fetch client credentials.
Because Wine is used to check cross compiled dbus for windows, in calls to GetExtendedTcpTable()
we use table class TCP_TABLE_OWNER_PID_ALL instead of TCP_TABLE_OWNER_PID_CONNECTIONS.
This class is the only one which is available since wine 1.5.3.

Call unregister_and_free_path_recurse instead of find_subtree. Delete subtree
removal logic since it has been refactored into unregister_subtree and
attempt_child_removal.
This fixes sd_booted() to actually mean "have systemd init", which we need for
_dbus_init_system_log() to decide whether systemd journal is being used.

Windows also has numeric process IDs that fit in an unsigned long, so
there's no reason this has to be Unix-specific.

CMake provides a standardized way to cross compile packages by
using -DCMAKE_TOOLCHAIN_FILE at configure time.
Also recent distributions like opensuse provides up to date native mingw
binary packages and cross compile packages which reduces the cross
compile setup to package installation and setup of a cross tool chain file
as documented at http://www.vtk.org/Wiki/CMake_Cross_Compiling.
