A macro can be a source of problems, because the compiler has no type on
the arguments to make checks. Using an inline function allows to do those
checks, meaning clearer error messages, it provides clear info in case of
name collision, it is easier to maintain (no need for the hacky '\' for
multi-lines) and the scope of visibility can be controlled more easily (no
need for #undef).
The macro store_modifier had to face a slight change because its 2nd
parameter is used as a reference, which is now clearly visible in the
prototype of the function.

The definition in the local header was not correct; it works because gcc is
tolerant to this kind of errors but other compilers are not. The
declaration was creating a local variable in each file that call header,
and because it is not static gcc's linker will merge them. Other compilers
will at best complain for duplicate symbol, and at worst silently duplicate
the variable so it will not work as expected.
The variable is now moved to the existing structure meant for global
variables, so now the code is really clear about using a global variable
instead of a static/local one.
Took opportunity to add some missing 'static' attributes to some variables.

This patch is adding the core code needed to run the workspace pager.
Currently when called, a new frame presenting mini workspace images
are displayed at the bottom of the screen above other windows.
When clicking on one of the miniatures, the workspace is switched and
the frame is closed.
Drawbacks: a screenshot of the workspace is used for the miniatures.
This screenshot is taken only when a workspace switched event occurs.
First, it means that the workspace switching process can be longer than
usual. Secondly, updated minitatures can only be available when the
workspace is "opened" (cause windows have to be mapped to be able to
be copied).
So when wmaker is (re)started or when for example a window is moved to
another workspace the corresponding miniature is NOT updated.
(I did not find a clean and easy way to do so, feel free to share if
you have some ideas)
This path is adding the functions and variables needed for workspace pager preferences.
An option to enable/disable the workspace pager, and one to set a default background image.
There are a few cases in which nested functions are an helpful way to write
code, as this is explained in 'script/nested-func-to-macro.sh'. However,
some compiler do not support them (like clang), so this patch proposes an
elegant solution, where developers can get the benefit of them, but for
users they are automatically converted to C macro if needed.
The advantage of this solution is that we keep the code simple, there is no
hack in the source (like #ifdef and code duplication), yet still having the
full advantages.
The translation is done according to what have been detected by configure
(see the WM_PROG_CC_NESTEDFUNC macro) so that user has nothing to do.

Using a variable to store the return value that will be used later is not a
good idea, because it forces to track everywhere in the function when
needing to work on the function.

returns False (meaning the event was not treated), whose root cause was

As pointed by Germán Arias, some windows in GNUstep did not have a title
bar because they declare themselves with the NET_WM type MENU.
A closer look at the spec shows that this type is meant for stuff like tear
off menus, and thus like for toolbar it is not expected that the
application does not want a titlebar, as opposite to DROPDOWN_MENU,
POPUP_MENU and COMBO.

As Coverity pointed, when building the command line to execute the current
code just assumed that it would fit in the large buffer. If user were to
provide a line too long, this would crash.
Factually this is probably not possible at current time because the command
given to the function was actually already limited to the MAXLINE size when
it was read, but this may not be guaranteed in future evolution.
Better safe than sorry, so the patch implement a size check when appending
strings, using a more efficient method (strcat re-parse the destination
string from the beginning to find its end every time).
