Unlike normal snapshots, no part of a static snapshot is loaded into
the RAM when executed from ROM. Static snapshots rely heavily on
external magic strings.

In some use cases, you want to reliably copy jerry strings to buffer, even if it doesn't fit target buffer, but is acceptable to lose some bytes. In those cases, the documentation will now suggest using the substring function as an alternative instead.

Aborts are similar to exceptions except they are not caught by catch
and finally blocks. Callbacks should honor aborts as well and return
them without processing them. Aborts are never thrown by JavaScript
code.
In the future certain events such as out-of-memory condition may
also throw aborts.

The #2043 introduced a bit of error in the API
docs as there was missing backticks.

Added two new api functions:
* jerry_parse_and_save_function_snapshot
* jerry_load_function_snapshot_at
The jerry_parse_and_save_function_snapshot function allows
creating snapshots from snapshot arguments and body source.
The jerry_load_function_snapshot_at function enables loading
back functions from a given snapshot as a JS function object.

This patch adds an extension to snapshots which allows storing
multiple position independent primary functions in a single
snapshot data. A new application called jerry-snapshot is
added to the project to manage snapshots. Currently the only
option is merging snapshots.

Markdown files in the docs/ directory can now be annotated to turn
fenced C code blocks into unit tests. The recognized syntax is:

```c

The commit also fixes the issues revealed during the initial
annotation.

`jerry_has_property ()` and `jerry_has_own_property ()` are inconsistent
in that they squash their return value into a `bool` when in fact it is
a `jerry_value_t`, thereby giving the wrong impression that a property
is there when it isn't and encouraging the leaking of `jerry_value_t`s
by disguising them as `bool`s.

This approach has the benefit that it does not require any *a priori*
initialization, and that each context pointer is identified by the way
in which it was created. Additionally, retrieving the context pointer
now requires that the entity responsible for creating/destroying it
(the manager) be given. Since managers are stored in global static
const structures, they should not normally be visible across source
files, and thus there should be no danger that a context item will be
retrieved by the wrong manager and thus cast into the wrong data type.
Since the items are stored in a linked list, their number will be
limited to exactly as many as are needed for a given context, with the
caveat that storing too many on a context will cause slow retrieval.
Thanks @mhdawson for the idea!

Based on feedback I got from people who tried using the new API, it was not immediately clear how to properly use it.
Hopefully these doc additions make it more clear how to use it and why it is designed the way it is.
Also fixed some mistakes in the example and provided more comments to explain the intent of the code.

This modification makes it possible to initialize a context in such a
way that a `void *` pointer is stored inside the context and is made
available via a new `jerry_get_user_context()` API.
The pointer is initialized via a new `jerry_init_with_user_context()`
API, which calls the existing `jerry_init()`, after which it sets the
value of the new `user_context` element in the `jerry_context_t`
structure using the context allocation callback provided as the second
parameter to the new `jerry_init_with_user_context()` API. The location
of the cleanup function responsible for deallocating the pointer created
by the context allocation callback is provided as the third parameter.
This location is stored in the context along with the pointer itself.
When a context is discarded via `jerry_cleanup()`, the user context
cleanup function is called to dispose of the pointer stored within the
context.
The semantics behind the API are such that it is now possible to choose
for each context an agent which manages arbitrary user data keyed to the
given context. The agent must be chosen at context instantiation time
and cannot be changed afterwards, remaining in effect for the lifetime
of the context.

This function can be used to save literals into a specific file in a list or C format.
These literals are valid identifiers, and doesn't match to any magic-string.
The '--save-literals-list-format FILE' and '--save-literals-c-format FILE'
options are used to save into the given file, when the snapshot-save is enabled.
The saved literals are sorted by size and lexicographically.
The C-format is useful for jerry_register_magic_strings() to generate the array
of external magic strings.
