* arch/z80/src/Makefile.sdccw: Renamed makefiles with extensions zdiil,
zdiiw, sdccl, and sdccw for the ZDS-II vs SDCC compilers and for the
POSIX vs Windows native builds.
* nuttx/drivers/mtd/ftl.c: Fix for the flash translation layer. Short
unaligned writes were buggy. From Petteri Aimonen.
* nuttx/libc/math/lib_round*.c: Add rounding functions to the math
library. Contributed by Petteri Aimonen.
* include/cxx/cstdlib: Add stroul(). From Petteri Aimonen.
* arch/*/include/limits.h: Change signed minimum values from, for example,
(-128) to (-127 - 1) to avoid overflows under certain conditions. From
Peterri Aimonen.
* graphics/nxtk/nxtk_subwindowmove.c: Previously it was very difficult to
do e.g. "scroll by dx, dy". When given the full window area, nxtk_subwindowmove
would clip the offset always to 0,0. It makes more sense for it to clip the
source area and not modify the offset. From Petteri Aimonen.
* graphics/nxtk/nxtk_getwindow.c: Clipping would change the offset of returned
data, and caller has no way to know what the new offset would be. This messes
up font drawing when the text is partially out of window, e.g. when scrolling.
Also from Petteri Aimonen.
* include/stdbool.h: Can now be disabled for C++ files if CONFIG_C99_BOOL8 is
defined. CONFIG_C99_BOOL8 indicates (1) that the sizeof(_Bool) is one in both
C and C++, and (2) the the C compiler is C99 and supports the _Bool intrinsic
type. Requested by Freddie Chopin.
* include/stdlib/lib_rand.c: Various additional changes so that the integer
value zero can be returned. Requested by Freddie Chopin.
