Fixed a memory leak in cfgfile_write_rom()
Fixed a conditional jump depending on an unitialized value in sdlgfx.c::graphics_setup()
puae 2.5.1
puae 2.5.1
Made sysdeps.h available using NO_MACHDEP macro for tools sources that have no machdep link. Further enhanced xcalloc, xmalloc, xrealloc and xfree for the beginning of the war against memory leaks.
Updated gencomp, gencpu and gengenblitter to use the new memory macros from sysdeps.h
Updated almost all locations using the old or direct memory management to use the new macros from sysdeps.h
Fixed a possible "free(NULL)".
Fixed a signedness issue
Removed explicit cast to (void*) from xfree macro. It is not needed right now.

However, this macro is overkill now and will be edited / replaced after the current hunt for memory leaks.
Removed obsolete prototypes and implementations of the old xmalloc, xcalloc and xfree functions.
Fixed gui-gtk to no longer crash. The widget type creation used a deprecated method and thus the wrong types.
Added libSDL_ttf and libSDL_image for non-MacOS builds using SDL UI.
Removed SDL framework include paths for non-MacOS builds.
Added missing includes and prototypes.
Added missing prototypes and functions for the gfx-x implementation. Fixed a possible crash
related to gfx-x in both src/drawing.c (security check) and src/gfx-x11/xwin.c (missing
assignement).
Fixed include order.
commented out the block using uaekey_make_default_kbr(), a function that is nowhere defined.
Added DX_Blit(), a function prototyped in picasso96.h but only used (as far as I can see) in xwin.c.
