The old unix-* session types are deprecated and will always
lead to a warning message "Unrecognized session type".

Internally there are only three session types: agent, proxy
and shadow, all the others are mapped to one of those three.

These keystrokes where the same as their viewport_scroll variants and made

This reverts commit 16cd2bbe.

It turned out that I had missed some of the Booleans being actually
tristate variables. I think I can fix this (they do not need to be
tristate) but I revert this for now to get back to a working state
(there are reports about non-working fullscreen mode and reconnect
problems).

drop "== False", "== 0", "== True" and "== 0" for nxagentOptions and Traps

In rootless mode skip processing user geometry stuff since the values will we
overwritten later anyway.

If nxagent is started in fullscreen mode take care the saved size
(that is applied on exit of the fullscreen mode) will be configured
correctly. Also respect a user provided -geometry option (had been
ignored here previously).

Fixes ArcticaProject/nx-libs#449

There's no need to reduce the size to 75% in rootless mode. We always
want to have the full size then.

... by using some short named variables and the min() macro.

No change in behaviour.

Minor fix: The loop always started at index 3, comparing against the
value at index 2. So the resolution at index 1 (320x240) was never
taken into account for anything.

This solves weird window (menu) placement and drawing behaviour on right/lowest
25% of the screen.

This fixes an assertion being triggered on reconnect:

assertion=assertion@entry=0x7f2f0bba6510 "(dpy->flags & XlibDisplayPrivSync) != 0", file=file@entry=0x7f2f0bba62fc "XlibInt.c", line=line@entry=895,

If X2go runs in auto keyboard mode it will pass keyboard=null/null to
the agent and set the keyboard afterwards with setxkbmap. This patch
lets nxagent handle that situation internally (null/null will be
interpreted as clone) and disables X2go's mechanism (by creating a dir
that effectively blocks it; see x2gosetkeyboard)

This is only activated if the agent is run as "x2goagent".

This avoids some roundtrips.

Add possibility to pass more than model and layout via the keyboard parameter.

Specifying -keyboard clone (or keyboard=clone in options) will clone
XKB keyboard from the remote x server. This way many keyboard problems
will hopefully never return...

Should be the default but is not (yet) for compatibility reasons.

Fixes ArcticaProject/nx-libs#373

(except the "do autoconf if no keyboard is provided" feature.)

It may not fully fix the issue mentioned below but it does for the
-keyboard commandline option at least.

we have changed that to base some time ago.

It will now create better working config files.
