g_cfg->xorg_params, g_cfg->vnc_params and g_cfg->rdp_params don't have
auto_free enabled, so removing an item from one of those lists won't free
its contents.
It's better not to change those lists, as they represent the actual
config file and could be reused. Instead, omit the 0th parameter (the
executable path) from copying to xserver_params.

In RHEL and its clones, /usr/bin/Xorg is set suid-root. To execute
Xorg with user privileges, /etc/pam.d/xserver needs be edited [1],
or suid bit of Xorg binary needs to be dropped.
In order to keep Xorg and /etc/pam.d/xserver untouched, preparing
non-suid version of Xorg as /usr/bin/Xorg.non-suid for example is
the simplest solution. However, Xorg.non-suid cannot be executed
since it is hardcoded to execute Xorg in sesman.
This change makes more flexible to execute Xorg with non-standard
name or not in PATH environment variable.

tm_mon in `struct tm` uses 0 for January.
`struct session_data` and `struct SCP_DISCONNECTED_SESSION` don't specify
how dates are stored. But considering the code in sestest and sesadmin,
all date components are stored as displayed.
The session match logic had two versions - one for the
SESMAN_SESSION_TYPE_XRDP and SESMAN_SESSION_TYPE_XORG sessions and one
for every other type. The only difference was, that different display
sizes where ignored when searching for sessions to reconnect if the
policy does not have the SESMAN_CFG_SESS_POLICY_D flag set and the type
is SESMAN_SESSION_TYPE_XRDP or SESMAN_SESSION_TYPE_XORG.
The reason was that xvnc cannot resize and the others can do. This two
versions where not necessary because we set the
SESMAN_CFG_SESS_POLICY_D flag every time we have a xvnc session a few
lines above. So the two branches for the different types can be reduced
to one.
