We shouldn't assume that xrdp daemon is running under root privilege.
In many cases, root privilege is not really needed for xrdp daemon.
xrdp may fail to load certificate/privkey due to lack of permissions
when running under user privilege. Checking existence of files is not
enough and xrdp should output user-friendly log in such case.

The UK/GB keyboard doesn't work properly connecting to xrdp with xorgxrdp.
It does work when connecting to xrdp with x11vnc, however.
This is because the layout is not declared in xrdp_keyboard.ini. It needs
to be called "gb" not "uk". (There are other layouts that have
km-nnnn.ini files that aren't declared in xrdp_keyboard.ini, so they might
have the same bug, but I haven't tested that. This is analagous to the
commits for the "ch" and "pl" layouts.)
Test case:
1. Use a PC with the UK/GB keyboard layout.
2. Create /etc/xrdp/startwm.sh as follows:
#!/bin/sh
export LANG=en_GB.UTF-8
export MDM_LANG=en_GB.UTF-8
export XTERM_LOCALE=en_GB.UTF-8
xterm
exit 0
3. Connect using rdesktop to localhost (from a session where the same
environment variables are defined).
4. Test layout-specific keys such as:
\ (backslash)
| (bar)
# (numbersign)
~ (asciitilde)
£ (sterling: Shift-3)
€ (EuroSign: AltGr-4)
These keys should produce the appropriate symbol but they don't. With
the change in this commit the keys produce the correct symbol.
As some clinents (AFAIK Windows 10) always send domain name, the backend
module is not selected properly. This causes the default usage with
Windows 10 fails with 'xrdp_wm_log_msg: Section "XXX" not configured'.
painter and librfxcodec are enabled by default. --disable-* options
disables them.
Before:
--disable-painter Use included painter library (default: yes)
--disable-rfxcodec Use included librfxcodec library (default: yes)
After:
--disable-painter Do not use included painter library (default: no)
--disable-rfxcodec Do not use included librfxcodec library (default:
no)

which is used to store login name. The login name shall be the string
that would be returned by the getlogin() function [1]. Some applications
only refers LOGNAME environment variable and don't fallback to other
variables such as USER.

Use XRDP_SOCKET_PATH in file_loc.h
Don't define any non-socket paths in file_loc.h, they should come from
the makefiles.
Define all paths unconditionally, they should not be defined elsewhere.
Pass XRDP_SOCKET_PATH as environment variable to the backends.
xrdp_chansrv_%8.8x_main_term and xrdp_chansrv_%8.8x_thread_done are both
wait objects, not sockets. They are created and cleaned up in chansrv.c
Wait objects are pairs of file descriptors on POSIX. They are closed
automatically when the process exits.
On Windows, wait objects are handles that are closed by CloseHandle().
Those handles should also be closed on the process exit.
In any case, there is no way for a parent process to clean up file
handles of the child process.
