The cache stores only real properties now, because storing NULLs has
little benefit according to tests. Since only real properties are
stored now, there is no need to create real references to objects
and property names, which reduces the keeping of dead objects after
garbage collection.

- The free_flags variable is removed from the vm_loop

- The VM_OC_POP opcode has no result, so the break is changed to continue.
- The VM_OC_PUSH_NUMBER can use ecma_make_integer_value.

Jerry (the command line tool) has been supporting the execution of
multiple script files for long. However, until now, it simply
concatenated all sources into a single source buffer and
parsed/executed them as one unit. Other JS execution tools (e.g.,
jsc, v8) load and execute separate files as separate units -- but
still in the same execution environment. The most significant
effect of this approach is that the `"use strict;"` directive (or
the absence of it) at the beginning of each JS script file takes
effect as expected (i.e., as if the script was executed alone).
Contrarily, the concatenation-based approach forces the strictness
of the first script on all the rest (i.e., if the first script
starts with `"use strict";` the rest is also executed in a strict
environment even if they did not contain the directive, and vice
versa).
This patch makes the jerry command line tool to load/parse/run one
unit at a time.
Side effects:
- As there is no need for separate file read routines that load one
file (a snapshot) or concat multiple (JS sources) anymore, those
routines got merged.
- Both previous read routines used multiple stdio functions
(`fseek`, `ftell`, and `rewind`). This has been simplified to
rely on `fread` only to find out the length of the input.
- This simplification made the above mentioned functions
superfluous in jerry-libc.
- As some error messages had to be touched in this patch, several
more have been beautified to make them more consistent.
- One small change was needed in `jerry_parse` in jerry-core to
allow subsequent parsing of multiple sources (without that, an
assertion was triggered).

Recent changes eliminate the need for `jerry_port_putchar`. As port
API discussions don't make it likely that it will ever be needed
again, this patch removes its declaration from jerry-port.h and its
implementations from the port(s).
The related code in jerry-libc is not needed either: whatever `putc`
(and `puts`) can do, `printf` can do as well.

The internals have surprisingly large number of unused functions at
surprising places. This patch cleans them out to make maintenance
easier and to prevent dead code having effect on future decisions.
The patch intentionally does not try to clean up public API but
focuses on internal modules only that are/should not be reachable
from "outside".
However, unit tests do access private API, thus tests of literal
storage had to be adjusted.

Replaced `gettimeofday`-related code with `jerry_port_get_current_time`
and `jerry_port_get_time_zone` function calls. Moved old code to
default port implementation.
Removed `ENABLE_DATE_SYS_CALLS` as date syscalls should "just work".
Fix DST adjustments: even if `gettimeofday` returns meaningful data in
`tz_dsttime`, the value is just a flag (or, according to some sources,
a tri-state value: >0 if DST applies, ==0 if DST does not apply, <0 if
unknown). Hitherto, the field was simply added to/subtracted from a
time value in milliseconds. To use it approximately correctly, the
field's value should be multiplied by "millisecs/hour".

* Moved the error codes to jerry-port.h and declared port function
`jerry_port_fatal`.
* Moved "exit or abort on fail" functionality to the newly added
jerry-port-default-fatal.c.
* This implied that a default port-specific API had to be introduced:
functions `jerry_port_default_set_abort_on_fail` and
`jerry_port_default_is_abort_on_fail` declared in jerry-port-default.h
control the fatal exit behaviour.
* For the sake of clarity, renamed jerry-port.c to
jerry-port-default-io.c.
* Adapted CMakeLists to deal with port implementations consisting of
more then one source file and exposing headers. This also required
the renaming of `EXTERNAL_PORT_FILE` cmake option to
`EXTERNAL_PORT_DIR`.
* Adapted main sources to use the default port header for the
abort-on-fail functionality, as that is not part of the core jerry
API anymore.
* Added default port implementation to the static source code checker
tools.
