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.

ECMA_GET_POINTER is removed from:
- property list iteration
- lexical environment chain iteration
- prototype chain iteration
For all these iteration the compressed pointer can be used to get the elements and only decompressed them if it is necessary.
- Properly guard ecma property hashmap routines
- Remove the redundant NULL pointer check from ecma_create_property
- Remove ecma_gc_get_object_next since it became unnecessary
- Substitute ECMA_{GET,SET}_POINTER with ECMA_{GET,SET}_NON_NULL pointer when we can assume the pointer is not NULL
- Remove ecma_get_object_prototype and ecma_get_lex_env_outer_reference helper function the reduce the number of NULL pointer checks during decompressing the pointers
- Remove ecma_get_named_accessor_property_{getter,setter} helper functions for also reduce the number of NULL pointer check/decompressions
- Remove ECMA_PROPERTY_SEARCH_DEPTH_LIMIT since in ES5 there is no way to create circular prototype chain, and the ES2015 setPrototypeOf method can resolve this error so this check during the property lookup can be eliminated.

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.

It is superfluous to maintain multiple globals when the whole
reason of context is to keep them in a single place. It also
simplifies initialization and external context creation a bit.
Also removed unused lcache header includes.

This fixes some conversion errors one gets when compiling with
LLVM/clang. Most of them are caused when a bit-specific type (i.e.
`uint16_t`) is implicitly cast to an `enum` of smaller value range.
The fix is just an explicit casting of those types to the desired target
type.

There are some leftover global functions in the code that are not
referenced at all anymore. These functions are removed by this
patch.
There are also some global functions that are only used in their
own modules. These functions are made static by this patch.

`JERRY_UNREACHABLE`s often signal code structure that could be
improved: they can usually either be rewritten to `JERRY_ASSERT`s
or eliminated by restructuring loops, `if`s or `#if`s. Roughly,
the only valid occurences are in default cases of `switch`es. And
even they can often be merged into non-default cases.
Moreover, it is dangerous to write meaningful code after
`JERRY_UNREACHABLE` because it pretends as if there was a way to
recover from an impossible situation.
This patch rewrites/eliminates `JERRY_UNREACHABLE`s where possible
and removes misleading code from after them.

In general, public headers should not have compiler-specific
constructs but both the core and the port headers have attributes,
which are non-standard. It's better to factor out such constructs
to a common place (a new header) and hide them behind macros, which
can then be defined on a per-compiler basis.
This patch moves the existing definitions of function attributes and
likely/unlikely builtins to the new header. At the same time, it
unifies the names of these attribute defines and where they are
used. Moreover, it touches on jerry-main and removes the uses of
`__attribute__((unused))` entirely and replaces them with the
elsewhere used `(void) ...` pattern.

Unlike normal snapshots, no part of a static snapshot is loaded into
the RAM when executed from ROM. Static snapshots rely heavily on
external magic strings.
JerryScript-DCO-1.0-Signed-off-by: Zoltan Herczeg zherczeg.u-szeged@partner.samsung.com
Direct strings are a new type of direct ecma-values (no memory allocation
is needed for encoding them) in JerryScript. Currently magic strings,
external magic strings and uint values are encoded as direct strings.
The constant pool of JerryScript byte-code is changed to hold ecma-values
rather than cpointers to support direct strings.

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.
