This lead to to PAM session modules not being properly initialized, with a potential consequence of incorrect configurations or elevation of privileges, aka a pam_limits.so bypass (bsc#1029912).

(bsc#1014524) - Avoid use of hard-coded sesman port. (bsc#1060644) - Backport upstream commit 5575197, sesman should stop setting LANG and let initialization scripts take care of it (bsc#1023988). - Backport upstream patches for 32bpp support (bsc#1022098). - Fixed a regression connecting from Windows 10.
