There are quite a few configuration macros in the project. As discussed in the #2520 issue there are a few awkward constructs. Main changes: * Renamed all CONFIG_DISABLE_<name>_BUILTIN macro to JERRY_BUILTIN_<name> format. * The special JERRY_BUILTINS macro specifies the basic config for all es5.1 builtins. * Renamed all CONFIG_DISABLE_ES2015_<name> to JERRY_ES2015_<name> format. * The special JERRY_ES2015 macro specifies the basic config for all es2015 builtins. * Renamed UNICODE_CASE_CONVERSION to JERRY_UNICODE_CASE_CONVERSION. * Renamed ENABLE_REGEXP_STRICT_MODE to JERRY_REGEXP_STRICT_MODE. * All options (in this change) can have a value of 0 or 1. * Renamed ENABLE_REGEXP_STRICT_MODE to JERRY_REGEXP_STRICT_MODE. JERRY_REGEXP_STRICT_MODE is set to 0 by default. * Reworked CONFIG_ECMA_NUMBER_TYPE macro to JERRY_NUMBER_TYPE_FLOAT64 name and now it uses the value 1 for 64 bit floating point numbers and 0 for 32 bit floating point number. By default the 64-bit floating point number mode is enabled. * All new JERRY_ defines can be used wit the `#if ENABLED (JERRY_...)` construct to test if the feature is enabled or not. * Added/replaced a few config.h includes to correctly propagate the macro values. * Added sanity checks for each macro to avoid incorrectly set values. * Updated profile documentation. * The CMake feature names are not updated at this point.
