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.

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).

* 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.

In case of literals and in main, snapshot saving is incorrectly
named dumping. Elsewhere in the code, 'dump' functions output debug
data (even literals have a `lit_dump_literals` debug function). To
help distinction and to align terminologies, snapshot saving
functions of literals and command line options of main are also
re-named 'save'.

E.g.,
* `ssize_t` was used where `lit_utf8_size_t` or `jerry_api_size_t`
would have been correct,
* `lit_utf8_size_t` was used where `ecma_length_t` would have been
correct.
Note, the patch also includes internal and public API changes:
* `ecma_string_to_utf8_string` does not return negative value if
output buffer is not large enough to contain the string; the
buffer is expected to be large enough. (`ecma_string_get_size`
can be used to retrieve the required size.)
* `jerry_api_string_to_char_buffer` adapts the same logic (and
`jerry_api_get_string_size` can be used to determine the
required size of the buffer).
