Fixes two bugs in the index calculations that affect the result
of the `String.startsWith` function:
- Fixes the implementation of ECMA-262 v6, 21.1.3.18, step 14:
"If searchLength+start is greater than len, return false".
- Fixes the return value of the helper function
`ecma_builtin_helper_string_find_index`. If it is called with a
starting search position, the returned index should be
not less than that.
These changes fix the following test cases in the test262 suite:
- built-ins/String/prototype/startsWith/return-true-if-searchstring-is-empty.js
- built-ins/String/prototype/startsWith/searchstring-found-with-position.js

This patch removes the ecma_property_descriptor_t structure bitfields and substitutes it with an uint16_t flag field
to reduce the cost of the transformation from/into the ecma_property_flags_t.
Also the is_throw last arguments is embedded to the property descriptor structure during the property defining process to reduce the number of arguments of the function.

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.

Since the project is now hosted at the JS Foundation we can move to unified copyright notices for the project.
Starting with this commit all future contributions to the project should only carry the following copyright notice (except for third-party code which requires copyright information to be preserved):
"Copyright JS Foundation and other contributors, http://js.foundation" (without the quotes)
This avoids cluttering the codebase with contributor-specific copyright notices which have a higher maintenance overhead and tend to get outdated quickly. Also dropping the year from the copyright notices helps to avoid yearly code changes just to update the copyright notices.
Note that each contributor still retains full copyright ownership of his/her contributions and the respective authorship is tracked very accurately via Git.

Fixed doc comments issues:
* Fixed mistyped param doc comments (`/**<` is OK, `/** <` is not).
* Put special characters (e.g., pipe, backslash, etc.) in quotes, as they can
confuse doxygen and it will print lots of various warnings. For the sake of
completeness and consistent style, also quote some special characters in
re-bytecode.h
* Added missing `@{`s, removed extra `@}`s.
* Turned `/*` comments to `/**<` doc comments.
Ensured same style for doc groups everywhere:
* Where `\addtogroup`, `@{`, and `@}` doxygen commands are used, the order to be
followed is: license, `#ifndef` guards (in headers), includes, `\addtogroup`
and `@{`, main code content, `@}`, `#endif` guards (in headers).
* Multiple `\addtogroup`s or multiple `@}`s should be in the same doc comment.
* First `\addtogroup` should be on the very first line of a doc comment, i.e.,
`/** \addtogroup`.
