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).
