these can be used to determine the PID and name of an X11 client,
e.g. in debugging.

One question remains: why are we using "bool" instead of "Bool" here?

has been used as integer sometimes (technically correct, but not nice)

    Bug #7186: Fix an excessive request size limitation that broke big-requests.

    MAXBUFSIZE appears to be a leftover of some previous time.  Instead, just
    use maxBigRequestSize when bigreqs are available (limiting buffers to ~16MB).
    When bigreqs are not available, needed won't be larger than the maximum
    size of a non-bigreqs request (256kB).

Call checkX2goAgent much earlier (in ddxProcessArgument) and adapt NXAGENTWINDOWNAMELENGTH to its result.

Same as in nxcomp's option handling. We really only need it for ","
(%2C) and "=" (%3D), currently, but it can handle all encoded
characters.

new name is more descriptive

We do not need two versions in the code

Attributes GH PR #721: https://github.com/ArcticaProject/nx-libs/pull/721

Windowsize was wrong when run with nxagent :<someDisplay>.

Basically three changes:
- reference sizeHints and wmHints correctly (no &)
- do not use uninitialized wmHints
- set wmHints Xutf8SetWMProperties() call instead of separate call
