Removed 'jerry_parse_and_save_literals' and introduced
'jerry_get_literals_from_snapshot' instead which works
on snapshot buffers rather than source code. Added literal
saving feature to snapshot merge in the snapshot command
line tool. Also added missing 'jerry_cleanup()' calls to the
snapshot tool. Improved the console messages of the snapshot
tool.

Under the cover of the debugger transport layer, allocation on the
engine's heap has been made available to the public. As there are
actually no restrictions on what the allocated memory can be used
for, the memory management functions better fit in the core part
of the API.

Closes #1805

There was quite some confusion about terminology around instances
and contexts. All the docs mentioned external contexts but
functions and types were referring to instances, and the relation
between these two concepts were not clear. This commit keeps
(external) context as the only surviving concept.

- Moved global context's `JMEM_HEAP_SIZE` to jcontext.h as external
  context's heap size is declared there, too.
- Moved the assert on `jmem_heap_t` vs `JMEM_HEAP_SIZE` to jcontext.c,
  as both entities are declared in the corresponding header.
- Removed superfluous checks on `JMEM_HEAP_SIZE` as it is not a
  publicly configurable macro (opposed to `CONFIG_MEM_HEAP_AREA_SIZE`).
- Ensured that all definitions of and references to `jmem_heap_t`,
  `JERRY_HEAP_CONTEXT`, `JERRY_HEAP_SIZE`, and `JERRY_HEAP_AREA_SIZE`
  are guarded by `#ifndef JERRY_SYSTEM_ALLOCATOR`, as they are
  meaningless if the system allocator is used.

The commit also contains some stylistic changes in jcontext.h

It is superfluous to maintain multiple globals when the whole
reason of context is to keep them in a single place. It also
simplifies initialization and external context creation a bit.

Also removed unused lcache header includes.

The `[jerry|ecma]_char_ptr_t` types are some old legacy that are
used quite inconsistently. Their `[jerry|ecma]_char_t *` variants
are used a lot more often, so it's better to stick to one form
throughout the code base.

This will help to keep the debugger documentation up to date.
(Note: only compilation & linking is possible as execution would
require a connecting debugger client, which is not supported for
unit/doctests.)

Rationale:
- There is no port under targets/ that would use it. All of them
  turn it off when building.
- That's no surprise, as jerry-libc supports no barebone MCUs but
  posix targets with syscalls only. Actually, that's Linux only,
  because macOS builds have turned off the use of jerry-libc a
  while ago.
- And there is no point in maintaining a highly restricted set of
  libc functions: as soon as someone wants to use JerryScript in a
  scenario that needs more functions than jerry-main, they have to
  choose a different libc (most problably the compiler's default
  one).

I think that we should not keep supporting an otherwise unused
library for the purposes of jerry-main on arm/x86/x64-linux  only.

This fixes some conversion errors one gets when compiling with
LLVM/clang. Most of them are caused when a bit-specific type (i.e.
`uint16_t`) is implicitly cast to an `enum` of smaller value range.

The fix is just an explicit casting of those types to the desired target
type.

The patch also ensures that all components access only the public
headers of other components (except for unit tests, which are
allowed to use private headers, too).

This helps to avoid the use of non-public headers and
protocol-internal constants in external code (e.g., in jerry-port
and jerry-ext).

The patch also cleans up the necessary includes in jerry-core public
headers, and the include order in jerry-port/default public headers.

`FILE_PATTERNS` is a space-separated list, in contrary to what is
suggested by its documentation. The pattern `*.h, *.c` does not
match header files but files with `.h,` extension only. Rewriting
the current comma-separated pattern makes Doxygen actually process
header files. However, it also reveals several hitherto hidden
issues (mostly missing documentation) in the code. This patch fixes
some of these documentation problems (and lists the files with
outstanding issues in a 'backlog').
