The file `main-unix.c` contained a lot of recurring patterns in the
command line option handling parts. This patch removes these code
clones with the introduction of two helper functions. The goal of
the patch is to have a smaller and maintainable `jerry` tool (mostly
source-wise).

Until now, it was not possible to query the engine whether its
build configuration contained debugging support. This commit adds
the `JERRY_FEATURE_DEBUGGER` label to `jerry_feature_t` and extends
`jerry_is_feature_enabled` to support the new feature flag.
Additionally, the command line tool `jerry` was enhanced to report
a warning when invoked with `--start-debug-server` but linked to a
non-debuggable engine.

Add a notification for JerryScript API users that the jerry-api.h
will be removed in the future and should use the jerryscript.h
header instead.
Also update the examples in the docs and the targets where
the jerry-api.h is used.

The debugger supports setting breakpoints, execution control (step, next, continue)
and getting backtrace. The communication is WebSocket-based, so a browser can
communicate with JerryScript without any intermediate application.

This function can be used to save literals into a specific file in a list or C format.
These literals are valid identifiers, and doesn't match to any magic-string.
The '--save-literals-list-format FILE' and '--save-literals-c-format FILE'
options are used to save into the given file, when the snapshot-save is enabled.
The saved literals are sorted by size and lexicographically.
The C-format is useful for jerry_register_magic_strings() to generate the array
of external magic 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the codebase with contributor-specific copyright notices which have a higher maintenance overhead and tend to get outdated quickly.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.

This patch improves the command line tool in two ways:
* The tool can be instructed to read and execute a script from
stdin by invoking it as `jerry -`.
* The tool can be instructed to suppress its prompt when in repl
mode by invoking it as `jerry --no-prompt`.

* Print location on parser errors.
* Do not print messages on parse error if FEATURE_ERROR_MESSAGES is not set.
* Minor style fixes

Previously, jerry-core was built with various build identification
info (build date, git commit hash, git branch name), which was both
available from string constants of the library and also exposed by
jerry-main via the `--version` command line option. As of late,
jerry-core identifies itself only with API version number macros,
but sometimes it could be helpful to get access to the git commit
hash as well, even if that info does not become part of the API.
This patch moves the git commit hash retrieval logic from the build
scripts of jerry-core to jerry-main, and changes `--version` handler
to print the hash as well.
Resolves#1295

OS X build regularly reports some 39 warnings falling in 3 major
categories:
* "static function '...' is used in an inline function with
external linkage [-Wstatic-in-inline]": Some semantics around
`inline` have changed between C89 and C99, and gcc and clang seem
to disagree on how strict they should be about them. Solution
chosen is to use `-Wnostatic-in-inline` command line option for
clang.
* "implicit conversion turns floating-point number into integer:
'double' to 'bool' [-Wfloat-conversion]": `if (fmod (..., ...))`
was used at different places, which is not nice anyway, thus the
return value is compared explicitly against `ECMA_NUMBER_ZERO`.
* "format string is not a string literal [-Wformat-nonliteral]":
Console and log port I/O functions have a printf-like interface,
and the default implementations actually pass both format string
and the remaining arguments to a vfprintf. However, clang is
strict about the format string parameter of vfprintf and expects
a literal there. By annotating the port I/O functions with
`__attribute__ ((format (printf, ..., ...)))`, clang will check
the format string being a literal string earlier, when the port
functions are called, and will not complain within them when
vfprintf is called.
(Actually, this has revealed an incorrect format string, which
has been fixed as well.)
(There were also some single conversion errors not listed above.)
The patch was tested on OS X (where all warnings disappeared), but
it should help clang compilation on other OS's as well.

- REPL mode also prints each error messages, not only each return values.
- If read_file fails, execution stops right away.

This patch:
* Ensures that all calls to `jerry_port_log` in jerry-core happen
via macros defined in jrt.h. Also, it unifies the names of those
macros: as `JERRY_ERROR_MSG` and `JERRY_WARNING_MSG` gave a good
pattern that was well aligned with the naming scheme of the log
level enum, `JERRY_DLOG` and `JERRY_DDLOG` were rewritten to
`JERRY_DEBUG_MSG` and `JERRY_TRACE_MSG`.
* Ensures that all debug logging code parts of jerry-core (i.e.,
memory statistics, JS byte-code dumps, and RegExp byte-code
dumps) are guarded by macros: `JMEM_STATS`,
`PARSER_DUMP_BYTE_CODE`, and `REGEXP_DUMP_BYTE_CODE`, which in
turn are controled by cmake build system feature flags
`FEATURE_MEM_STATS`, `FEATURE_PARSER_DUMP`, and
`FEATURE_REGEXP_DUMP`.
* Ensures that all debug logging functionalities can be controled
during run time (provided that they were enabled during build
time): the engine has `JERRY_INIT_MEM_STATS[_SEPARATE]`,
`JERRY_INIT_SHOW_OPCODES`, `JERRY_INIT_SHOW_REGEXP_OPCODES` init
flags, and the default unix/linux command line app has
corresponding command line switches.`
* Drops `FEATURE_LOG`, `JERRY_ENABLE_LOG`, and
`JERRY_INIT_ENABLE_LOG`, as their name was misleadingly general,
even though they mostly controled the regexp engine only. The
above-mentioned `*REGEXP*` things mostly act as their
replacements.
* Updates build, test, and measurement tool scripts, and
documentation.

We removed that implementation where the build directory isn't set up to build with exactly one
configuration of the project but potentially several variants: the same build directory
can/must be used for debug and release builds, for full or compact profile versions, etc.
So we reworked the CMakeLists, and now one build dir deal with exactly one configuration
of the project's libraries and tools.
