Khaled Hosny bff8fa97e1 Enable HarfBuzz by default 
HarfBuzz integration should be functional now, so to give it more wider
testing it is made now a required dependency on non-Windows non-Mac OSs.
By default text layout is now done by HarfBuzz but ICU LayoutEngine is
kept as a fallback and can be enabled with SAL_USE_ICULE env variable.

After 4.1.x is branched, ICU LayoutEngine should be removed completely.

README 

These are configuration files for various features as detected by configure.

Include only those files you need (in order to reduce rebuilds when a setting changes).

Settings here are only C/C++ #define directives, so they apply only to C/C++ source,
not to Makefiles.



Adding a new setting:
=====================

- do AC_DEFINE(HAVE_FOO) in configure.ac when a setting should be set
- choose the proper config_host/config_XXX.h file to use
    - if it is a global setting (such as availability of a compiler feature),
        use config_host/config_global.h
    - otherwise check if there is a matching config_host/config_XXX.h file
    - if none matches, add a new one:
        - add config_host/config_XXX.h.in here, with just #ifndef include guard
        - add AC_CONFIG_HEADERS([config_host/config_XXX.h]) next to the others
            in configure.ac
- add #define HAVE_FOO 0 to the config_host/config_XXX.h , possibly with a comment
  (do not use #undef HAVE_FOO, unless the setting has more values than on/off)
- add #include <config_XXX.h> before any #if HAVE_FOO in a source file
- make sure you use #if HAVE_FOO for on/off settings, do not use #ifdef
