Improve handling of color palettes.

This commit adds new functions to streamline palette access:

  FT_Palette_Set: Set a user-defined palette.
  FT_Palette_Get: Get palette and palette index.
  FT_Palette_Get_Foreground_Color: Get foreground color.

Fixes issue #1134.

* include/freetype/internal/tttypes.h (TT_FaceRec): Change type of
`palette_index` to `FT_Int`.  Negative values now represent user-defined
palettes.

* src/base/ftcolor.c (FT_Palette_Set, FT_Palette_Get,
FT_Palette_Get_Foreground_Color): New functions.

* include/freetype/ftcolor.h: Updated.

-
-  - TrueType interpreter version 38  (aka Infinality)  that was  first
-  introduced about 10 years ago  in FreeType 2.4.11  is now deprecated
-  and slated  to be removed in the next version.  TrueType interpreter
-  version 40  has been  FreeType default version  for  6 years now and
-  provides an excelent alternative.  This is the last FreeType version

-CHANGES BETWEEN 2.12.0 and 2.12.1
-
-  I. IMPORTANT BUG FIXES
-
-  - Loading CFF fonts sometimes made FreeType crash (bug introduced in
-    version 2.12.0)
-
-  - Loading  a fully  hinted  TrueType glyph  a  second time  (without
-    caching) sometimes yielded different rendering results if TrueType
-    hinting was active (bug introduced in version 2.12.0).
-
-  - The generation of the pkg-config file `freetype2.pc` was broken if
-    the build was done with cmake (bug introduced in version 2.12.0).
-
-
-  II. MISCELLANEOUS
-
-  - New option `--with-librsvg` for  the `configure` script for better
-    FreeType demo support.
-
-  - The  meson  build  no  longer enforces  both  static  and  dynamic
-    versions of the library by default.
-
-  - The internal  zlib library was  updated to version  1.2.12.  Note,
-    however, that  FreeType is *not* affected  by CVE-2018-25032 since
-    it only does decompression.

-  - Support for non-desktop Universal Windows Platform.

-   * @description:
-   *   A macro that returns true whenever a face object contains an 'sbix'
-   *   OpenType table *and* outline glyphs.
-   *
-   *   Currently, FreeType only supports bitmap glyphs in PNG format for this

-   *   Apple-specific formats not part of the OpenType specification).
-   *
-   * @note:
-   *   For backward compatibility, a font with an 'sbix' table is treated as
-   *   a bitmap-only face.  Using @FT_Open_Face with
-   *   @FT_PARAM_TAG_IGNORE_SBIX, an application can switch off 'sbix'
-   *   handling so that the face is treated as an ordinary outline font with
-   *   scalable outlines.
