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.

Introducing the `assert.h` public header with the `assert(x)` macro
and already making use of it in jerry-libc sources. These newly
introduced ISO C-conforming features replace the non-conforming
`LIBC_ASSERT` and `LIBC_NDEBUG` at no cost, and they also have the
benefit that we can expose `assert` in a public header and make it
useful to jerry-libc users.

Now, parser correctly finishes parse procedure if syntax of source code is incorrect (syntax correctness is indicated using return value):
- parser-internal memory management is performed using jsp_mm_alloc / jsp_mm_free;
- upon detection of incorrect syntax, all parser-allocated memory regions are deallocated using jsp_mm_free_all and parse finishes with corresponding return value.

Added declaration and implementations of `void abort (void)` to
jerry-libc. As the linux implementation relies on the `getpid`
syscall - which has no arguments - `syscall_0` implementations
have been added as well.
`libc_fatal` has been adapted to use the new `abort` function
instead of `exit`. This also made the definition of
`LIBC_FATAL_ERROR_EXIT_CODE` unnecessary.
Finally, the syscall fatal error message was fixed.
