move module related tests from test/box/ to test/module/.

closes #171

Change:
    box.space.name:insert() to box.space.name:insert{}
    box.space.name:replace() to box.space.name:replace{}
    box.space.name:delete() to box.space.name:delete{}
    box.space.name:auto_increment() to box.space.name:auto_increment{}
    box.space.name:select() to box.space.name:select{}
    box.space.name:update() now requires an explicit key and ops
    table.

Remove ellipsis from wrappers which don't strictly need it.
Remove backward-compatible next_equal/next/prev_equal/next/prev
iteration functions.
Cleanup hot_standby.test

Introduce constants for ids. Update tests.

    1. Unified blurb for every site page
    2. remove tnt-html.xsl.cmake tnt-html-chunk.xsl.cmake in favor of
    --stringparam and -param flags of xsltproc and saxon
    3. Create flags for input/output in static.py script for OOS build

All layouts are in doc/www-data.in/_layout and are written in Jinja1
(django-like templates). All texts are in doc/www-data.in/_texts

Text files contains YAML files with chunks of markdown strings:
```
$module:
    $uno: |
        some text in markdown
    $dos: |
        it may be multiline
    $tres: |
        # header 1
        ```
        may have some embedded code
        ```
        e.t.c
    ...
```
where `$module` is name of layout file, `$uno`, `$dos`, `$tres`... are
name of parts (template parts `{{ $module.$part }}`)
Site still stores files in `doc/www-data` for copying on server.
Also it integrates documentation (only on stable/master branches) into site (still templlates)
Usage of new `extra/static.py`:
```bash
$ cmake . -DENABLE-DOC=TRUE
$ make
$ cd /doc/www-data.in/
$ ../../extra/static.py site `# build site`
$ ../../extra/static.py docs `# embed docs`
```

 ### documentation building

Add `html-saxon-chunk` and `html-chunk` targets for building chunked
html documentation.

`make` in `doc/user` now builds `html-saxon` and `html-saxon-chunk`
targets

> remove script/ directory and move it's content to extra/

-related distributions due to libbfd crash

Fedora includes debug package by default and will
trigger an error if sees the duplicate.

binutils-devel for build.

Removed html files and added rtf files which uses in the DMG package, also enable readme section at an installer

before starting another one.

Still some issues with Lua console to fix, but transfer
big/sql.test to the new data dictionary at least.

Fix a bug found in the process that when altering an index
from unique to non unique the index is not rebuilt.

Remove 'lua ' prefix from schema_erase/schema_fill classes.

Store the information about spaces in a pre-recreated
system space.

https://blueprints.launchpad.net/tarantool/+spec/space-ddl

Remove space configuration from confetti.
Use transaction and space triggers to run post-DML
actions to perform DDL changes.

Implement a Lua FFI binding to disable tests.

Temporarily disable space-loading code in tarancheck
and tarantar (this breaks them).

Mostly all tests are broken.
Memcached is disabled (non-functional).

Rewrite --init-storage to dump a compiled-in blob
instead of firing off the entire save snapshot machinery.

This should simplify bootstrap in presence of system
spaces:
there's going to be no need to implement the
code which creates system, they will be created
simply by recovery from a snapshot.

@todo: manage instances in /etc/tarantool

The patch which removes the CPack-generated spec
and adds a proper spec for client, server and library
was done by Dmitry Simonenko.

Hand-port the patch to the master, since it's gone too
far away from the origin and merging it ends up in a mess.

- write the docs
- remove unnecessary introduction of Perl
- properly implement, document and test box.fiber.wrap()
- rename box.find, explore alternatives (none)
- rewrite box.unpack('R') to reuse code and do
what's expected of it.

* Rewrite box.net.box:
	- connection process is in internal fiber, so
	  connector can reconnect lost connections
* Add box.fiber.wrap function that runs new detached fiber
* Add some tests
