Since quite some time, the linkable libraries are stored in the .libs/
subdirectories.  Adjust libvncserver-config to account for that when
running without installing.

We cannot write access the frame buffer, and we do not have a sensible
cursor anyway, so better disable the cursor (which would have to be drawn
for clients that do not support CursorShapeUpdates).

Just like its siblings from other projects, SDLvncviewer now supports

        mode. -threads is now strongly discouraged.  Read PORT= in url.
        User can set nolisten for Xvfb in -create mode.  clean up
        wait_for_client() to some degree.

The JPEG library is not necessarily installed everywhere, and sometimes
it is outright undesirable to compile with JPEG support, e.g. when the
server is not very fast.  So fix the compilation for that case.

Highlite:
 * use qualityLevel/zlib_buffer. No new variable is needed.
 * Change coding style to recursive fashion.
 * Change meaning of qualityLevel== 9 for easy calc zywrle_level:
     old:zywrle_level== 1
     new:disable ZYWRLE(same as ZRLE)
   so, we should not use this value for compatible reason.
 * Color mode handling isn't complete.
   I provided and checked 16 bit colors(RGB555,RGB565) and
   some color mode of 32 bit colors for little endian mode.
   we must make and check 24 bit colors and big endian mode.

For some reason, I swapped buttons 2 and 3 on Dec 7, 2005, in commit
"translate keys based on unicode (much more reliable than sym)".
I do not remember why, nor what I smoked, but this was wrong.

There was a long standing TODO to make the counting of the supported
encodings dynamic.  It never triggered, until ZYWRLE was added.

Since we separated the packages LibVNCServer and x11vnc, there is
a configure switch --with-x11vnc, without which x11vnc is not built.

However, even _with_ this switch, it is not built, because the Makefile
would not recurse into the x11vnc/ subdirectory.  Fix that.

When swapping the values for the colour table to little-endian (because
they are 16-bit values), we need to cast "unsigned char" to "unsigned
short"; otherwise, Microsoft's compiler would keep complaining.

The variable tightQualityLevel is used for ZYWRLE compression, too,
so if libjpeg is not present, but libz is, we still need to have
that struct member.

ZYWRLE used a static buffer, which does not work too well if you have
more than one client in a threaded server.  Instead, we have the data
in the client structure now.

While adjusting the coding style, three stupid mistakes happened.  The
quality is _not_ just 1, 2, 3, but really 1, 3, 2.  And the macros
ZYWRLE_PACK_COEFF() and ZYWRLE_UNPACK_COEFF() expand to more than one
statement, which means that we need curly brackets around them when they
are in an if clause.
