This patch unifies the recursion limit checking for RegExp, function call and JSON as well.
Until now the limit was only a counter which was increased/decreased at certain points.
This counter has been substituted with a numeric limit which allows to restrict the stack usage.
This patch fixes#2963 and resolves the closed#2258 issue.

The current module implementation resolves module paths relative to the
current working directory, but paths should be resolved relative to the
currently evaluated module/source.
This requires a change in the jerry_port_normalize_path port API
function, so that it also takes the current module path as an argument.
On the engine side, we now also create a module object for the main
script, so that we can properly identify the base path for other
modules.

This PR is a general cleanup for garbage collection and memory
allocation code paths.
Changes:
* Removed an unnecesary local variable from 'ecma_gc_mark'.
* Refactored 'ecma_gc_run' to have an implicit list head during
iteration, which results in one less condition in the loops,
and changed the loops to use compressed pointers to reduce the
overall amount of compression/decompression.
* Renamed 'jmem_free_unused_memory_severity_t' to 'jmem_pressure_t',
and added additional values.
* Removed 'jmem_free_unused_memory_callback', instead
'ecma_free_unused_memory' is now called directly.
* Reworked 'ecma_free_unused_memory' to handle all code paths related
to 'jmem_pressure_t', and moved all relevant code paths into this
function. This simplifies the code paths in other places.
* Reworked 'jmem_heap_gc_and_alloc_block' to be more streamlined.
* Changed mem-stats to not report unused pool chunks as allocated
memory.
* Created an allocator internal API for allocating/freeing memory blocks
that are not reported as used memory in mem-stats.
* Removed iteration statistics for the jerry allocator from mem-stats,
as they don't provide any actually useful information.

When using ES6 modules it was not possible to identify which module
an error originates from.
This PR changes the error message to also include the file path using
the file:line:column format, and updates the source context printing for
unhandled exceptions to use the correct file.

This patch slightly reworks the container objects internal objects allocation.
This rework allows the same lifetime of the objects without the manual allocation/deallocation of the internal object.

VM_RECURSION_LIMIT only prevented the recursion of interpreted codeblocks but
native/builtin function calls can also create stack overflow due to the too deep recursion.

Provide contributors with a checklist to ensure quality PRs and to
avoid common pitfalls. The items in the checklist are mostly beyond
the capabilities of automated checker tools and more like reminders
of best practices. Still, they can save lot of valuable reviewer
time (hopefully).
