As pointed by Coverity, it is possible to dereference the NULL pointer in
the function 'browseForFile'.
This should have been reported by the compiler ("possible use of
uninitialised variable") but the assignation of a default value to the
variable 'lPtr' hides this, but as the default value is not a good one then
the code could crash.
This patch removes the default value, so we may have some info from the
compiler and handles the case smoothly.
It also fixes a potential memory leak pointed also by Coverity in the
case where the string returned by WMGetFilePanelFileName would be a 0
length non-null string.

The functions that create the different configuration panels were taking
the screen structure as argument, but it turns out that none of them
actually need it.
We just remove the argument to make code simpler and easier to maintain.

The WINGs toolkit dispatch events on widgets using callbacks, which means
having a fixed argument list for the handling function.
It is then correct to not use all the arguments, so this patch adds the
appropriate stuff to avoid a false report from compiler.

memset is the last function call in wmalloc, just before it returns the
newly allocated memory. Therefore it is not needed to call it again
after wmalloc call. Although I would prefer to switch wmalloc to a
calloc-based wcalloc function, the compatibility of WINGs for old apps
should be kept.
Initialized variables that are conditionally set. In particular, this
construct is dangerous:
void *p;
if (something) p = couldReturnNull();
if (!p) p = fallbackFunction();

are affected. Fixes for old code too.
- Double buffering in WMList. All widgets or apps using WMList and
having user drawing porcedures in place will inherit this double
buffering automatically too.
- New functions in WINGs: WMGetColorAlpha(), WMIsAAFont()
- Misc code cleanups in WINGs and src/dialog.c
WMDrawString() and WMDrawImageString() now take WMColor instead of GC as
arguments. WMDrawImageString() receives 2 colors (text & background).
This is to allow easy extension for Xft/Xrender and hide X low level details
- Added alpha channel to WMColor. 2 new functions also:
WMCreateRGBAColor() and WMSetColorAlpha()
- Miscelaneous code cleanups in wtext.c
- Removed obsoleted acconfig.h and implemented its functionality using
AC_DEFINE and AC_DEFINE_UNQUOTED as autoconf 2.5x recommends.
This will definitely enforce the need to use autoconf 2.5x
- Separated the font caches for normal fonts and fontsets in WINGs (they can
have the same names and collide in the cache giving unwanted results)
- Updated the years in the copyright notices
- Also tested the backward compatibility ability of the WINGs proplist code
which seems to work quite well.
Starting with this moment, Window Maker no longer needs libPropList and is
now using the better and much more robust proplist code from WINGs. Also the
WINGs based proplist code is actively maintained while the old libPropList
code is practically dead and flawed by the fact that it borrowed concepts
from the UserDefaults which conflicted with the retain/release mechanism,
making some problems that libPropList had, practically unsolvable without a
complete redesign (which can be found in the more robust WINGs code).
