In either case of wlf_handle_touch_up()/wlf_handle_touch_down(), the
UINT16 flags are set to fixed values, so there is little reason for
checking presence of specific flag in them again. The conditional is
always true no less, so just call freerdp_input_send_mouse_event().
Moreover, the flags submitted to the remote are wrong. The code should
send BUTTON1/DOWN/MOVE on wlf_handle_touch_down(), so the remote would
pick not only the button down event, but also the coordinate update,
else the remote would receive a mouse click at the wrong coordinates.
The wlf_handle_touch_motion() should update the pointer location too,
make it send plain MOVE event.

The wlf_handle_touch_down() implements fallback to mouse event submission
in case RDPEI is not available. This fallback is currently never reached,
because the WINPR_ASSERT(rdpei); triggers before the fallback conditional
is reached.
Move the WINPR_ASSERT(rdpei); after the RDPEI availability check to permit
the fallback to do its job.

Covscan report contains various memory leak defects which were marked
as important. I have spent some time analyzing them and although they
were marked as important, most of them are in error cases, so probably
nothing serious. Let's fix most of them anyway. The rest are false
positives, or too complicated to fix, or already fixed in master, or
simply I am unsure about them.

For the negative scrolling direction, RDP uses the two's complement,
instead of the positive wheel value with the negative flag.
xfreerdp currently uses the positive wheel value in addition to the
negative flag, which results in a wrong wheel value on the server side
(136 instead of 120).
Fix this, by using the correct wheel rotation value, which is in the
two's complement.
the discrete axis event gives changes in steps just like the
xfreerdp version uses. This way scrolling can be implemented
consistent with the behaviour of xfreerdp
* client: Fix exit codes for /help and similar option
Currently, non-zero exit code is returned for /version, /buildconfig, /help,
/monitor-list, /kbd-list and /kbd-lang-list command-line options for several
clients. This is against conventions because 0 is usually returned in
such cases. Also, there is potentially another problem that the returned
codes overflow on UNIX systems (where the exit code is a number between 0
and 255). Let's fix the clients to return 0 in the mentioned cases to honor
conventions and 1 for the command-line parsing errors (or -1 for clients
who already use that value).

* Refactored freerdp_client_settings_command_line_status_print_ex
Now returns 0 if help or version information was requested.
* Do not eliminate original error status.

This fixes the following defects reported by covscan tool:
- client/Wayland/wlf_input.c:251: overrun-local: Overrunning array "contacts" of 10 32-byte elements at element index 10 (byte offset 351) using index "i" (which evaluates to 10).
- client/Wayland/wlf_input.c:308: overrun-local: Overrunning array "contacts" of 10 32-byte elements at element index 10 (byte offset 351) using index "i" (which evaluates to 10).
- client/Wayland/wlf_input.c:360: overrun-local: Overrunning array "contacts" of 10 32-byte elements at element index 10 (byte offset 351) using index "i" (which evaluates to 10).
- client/Wayland/wlf_input.c:251: error[arrayIndexOutOfBounds]: Array 'contacts[10]' accessed at index 10, which is out of bounds.
- client/Wayland/wlf_input.c:308: error[arrayIndexOutOfBounds]: Array 'contacts[10]' accessed at index 10, which is out of bounds.
- client/Wayland/wlf_input.c:360: error[arrayIndexOutOfBounds]: Array 'contacts[10]' accessed at index 10, which is out of bounds.
- client/Wayland/wlf_input.c:246: uninit_use_in_call: Using uninitialized value "y" when calling "wlf_scale_coordinates".
- client/Wayland/wlf_input.c:246: uninit_use_in_call: Using uninitialized value "x" when calling "wlf_scale_coordinates".
The maximal number of touches can be higher then 10, see:
https://wayland.freedesktop.org/libinput/doc/latest/touchpads.html
Let's increse the MAX_CONTACTS count and add checks to prevent usage of
uninitialized values.
