The flag handling (both compiler options and include paths) are a mess at
the moment.  There is no point in forcing "-O2 -g" when these are already
the defaults, and if someone changes the defaults, chances are good they
don't want you clobbering their choices.

The -Wall flag should be handled in configure and thrown into CFLAGS once
rather than every Makefile.am.  Plus, this way we can control which
compilers the flag actually gets used with.

Finally, the INCLUDES variable is for -I paths, not AM_CFLAGS.  Nor should
it contain -I. as this is already in the default includes setup.

Newer autoconf fails if _cv_ is not in the cache var name.

Newer automakes error out due to per-file CFLAGS being used unless the
macro AM_PROG_CC_C_O is set in configure.ac.

[jes: The macro AM_PROG_CC_C_O has been around since 1999, so it should
 be safe.]

prepare_x11vnc_dist.sh: set version to 0.9.7

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.

Thanks to Guillaume Rousse, we now use libtool to build shared libraries.

 SSL Java viewer work thru proxy.  -sslGenCA, etc key/cert management utils for x11vnc.  FBPM "support".
