Thomas Wolff 44d90834fb fix/enhance Unicode table generation scripts
Scripts do not try to acquire Unicode data by best-effort magic anymore.
Options supported:
-h for help
-i to copy Unicode data from /usr/share/unicode/ucd first
-u to download Unicode data from unicode.org first
If (despite of -i or -u if given) the necessary Unicode files are not
available locally, table generation is skipped, but no error code is
returned, so not to obstruct the build process if called from a Makefile.

These tables provide character width properties for use by the
wcwidth/wcswidth functions. They are generated from Unicode.

Pat Pannuto e02866a1b4 Add missing headers to fix implicit function defns
A few files were missing headers for memset/malloc, likely missed
because the files don't directly call the functions, rather they
come in via macros in libc/include/sys/reent.h:

    #define _REENT_CHECK(var, what, type, size, init) do { \
      struct _reent *_r = (var); \
      if (_r->what == NULL) { \
        _r->what = (type)malloc(size); \

    #define _REENT_CHECK_ASCTIME_BUF(var) \
      _REENT_CHECK(var, _asctime_buf, char *, _REENT_ASCTIME_SIZE, \
        memset((var)->_asctime_buf, 0, _REENT_ASCTIME_SIZE))

Without these fixes, implicit function signatures are provided,
which gcc warns could cause aliasing issues down the line:

    ../../../../../../../newlib-2.5.0/newlib/libc/time/asctime.c:62:3: warning: type of 'memset' does not match original declaration [-Wlto-type-mismatch]

    /Volumes/code/external/newlib-cygwin/newlib/libc/include/malloc.h:37:13: note: code may be misoptimized unless -fno-strict-aliasing is used

Including the proper headers elminates the implicit function
signatures and these warnings.
