These Coverity warnings all relate to the user of g_setenv() where the
return result isn't checked.
An additional void function g_setenv_log() is provided which logs
failures to set environment variables, and returns no status. This is
used in all the places where g_setenv_is currently called.
Add an option to allow XAUTHORITY to be moved away from $HOME.
This is modelled on the lightm 'user-authority-in-system-dir' option,
and also current GDM default behaviour.
The top level socket directory is now called XRDP_SOCKET_ROOT_PATH.
Below that are user-specific directories referred to with the
XRDP_SOCKET_PATH macro - this name is hard-coded into xorgxrdp and
the audio modules as an environment variable.
XRDP_SOCKET_PATH now looks like $XRDP_SOCKET_ROOT_PATH/<uid>
XRDP_SOCKET_PATH is only writeable by the user, and readable by the user
and the xrdp process.
env.c : The value of XRDP_SESSION in the environment is now set to the
PID of the sesexec process, which ties up the session with the
output of "xrdp-sesadmin -c=list".
Later versions of xrdp-sesadmin can use this value to get
information about the current process.
