It fixes the following errors during tarantool installation from
packages on debian / ubuntu:

```
Unpacking tarantool (1.9.1.23.gacbd91c-1) ...
dpkg: error processing archive /var/cache/apt/archives/tarantool_1.9.1.23.gacbd91c-1_amd64.deb (--unpack):
 trying to overwrite '/lib/systemd/system/tarantool.service', which is also in package tarantool-common 1.9.1.23.gacbd91c-1
```

The problem is that tarantool.service file was shipped with
tarantool-common and tarantool packages both. It is the regression after
8925b862.

The way to avoid installing / enabling the service file within tarantool
package is to pass `--name` option to dh_systemd_enable, but do not pass
the service file name. In that case dh_systemd_enable does not found the
service file and does not enforce existence of the file.

Hope there is less hacky way to do so, but I don't found one at the
moment.

It is necessary for build on Ubuntu Bionic.

Since #1265 tarantool is fully compatible with lua5.1.
Install /usr/bin/tarantool as /usr/bin/lua alternative.

Closes #2730

Remove libbfd from dependencies and use libunwind for stack traces.

Closes #2103

LuaRocks requires openssl and curl in order to download
manifest from rocks.tarantool.org.

Fixes #2612

Usage:

    tarantoolctl rocks install ROCK - install a rock
    tarantoolctl rocks remove ROCK - remove a rock
    tarantoolctl rocks show ROCK - show information about an installed rock
    tarantoolctl rocks search PATTERN - search repository for rocks
    tarantoolctl rocks list - list all installed rocks

There are no other commands, options, configuration files. Our official
repository (http://rocks.tarantool.org) works out of the box. All rocks
are installed to ${PWD}/.rocks directory to support separate rocks trees
per project, as proposed by #2067. Rockspec can use "tarantool >= 1.7.x"
inside dependencies = {} block to depend on a specific Tarantool version.

LuaRocks has been slightly hacked to support custom configuration
via site_config.lua. There are no other changes in the upstream code.
It is not a fork and it isn't going to be a fork. All formats, layouts
and rockspecs are 100% compatible with the upstream LuaRocks 2017-07-10.

This feature intentionally doesn't have CMake option to disable it,
because it should be provided on all available platforms out of the box.

Other changes:

 * Add ${PWD}/.rocks to default package.path/package.cpath
 * Hack tarantoolctl to display subcommands in --help.
   Currently command line arguments handling are not perfect, but
   it can be fixed only by a new argparse implementation.

Closes #2067

dh_systemd_enable called BEFORE dh_install, which installs file(s)
(tarantool.service), required for dh_systemd_enable. A quick workaround
is to symlink tarantool.service into debian/ directory.

Issue appeared only in cdbs comming with Debian 9.

+ Fix inconsistent debian/changelog and debian/control.

Inpspired by tarantool/curl module by Vasiliy Soshnikov.
Reviewed and refactored by Roman Tsisyk.

Closes #2083

Set LimitNOFILE to 65535 to provide the best Vinyl experience
out of the box.

Closes #2465

Force tarantool-common upgrade to support systemd notifications.

+ Add missing "s" suffix to TimeoutStartSec= option.

See #1923

This patch removes following source files regeneration:
  1. keywordhash.h
  2. opcodes.[hc]
  3. parse.[hc]
  4. sqlite3.h
adding them to the source tree.

To re-generate them (p.p. 1-3) one must pass
-DSQL_MAINTAINER_MODE=ON option to cmake. Files will be
copied to source tree automatically iif actual difference will
be detected.

As far we don't need such platform variety - remove sqlite3.h
re-generation at all.
Remove TCL script responsible for generation and template header
as well.

Compilation of auxilary SQL tools was also moved under this option:
  1. Lemon parser
  2. mkkeywordhash
since they redundant in non-maintainer mode.

Finally it removes dependency on TCL from all Tarantool package
variants.

Remove sqliteConfig.h, we don't use it.

SQLite uses TCL shell to generate common headers.
Add dependency in Travis to TCL shell for linux targets.
OSX comes with TCL pre-installed - no need to add dependency.

	* .travis.mk (deps_linux): Add tcl.

sql: Add dependency to TCL in packages.

As far as SQLite sources depend on TCLsh we need to
add dependency to TCL in package info.

	* debian/control: Add dependency on TCL.
	* rpm/tarantool.spec: Ditto.
	* snapcraft.yaml: Ditto.

sql: Avoid multiline string to satisfy older cmake

RHEL uses some old cmake which doesn't work with long string
which span over few lines w/ '\' terminator. Make it single line.

	* src/box/CMakeLists.txt (set_source_files_properties): Use
	single line instead of vreaks w/ '\'.
