* In RPM/DEB we introduce new utility - tarantool_ctl (extra/dist/dist.lua)
* /var/pid -> /var/run
* Fix extra/dist/dist.lua
* /extra/dist/tarantool.init and /extra/dist/tarantool.service now
  are regenerated by cmake (paths to `dist.lua`)
* Systemd service (Uses sysv-init script)
* RPM Supports both systemd and init (by using '--with systemd' in
  rpmbuild flags)

This patch adds a new implementation of UUID library.
New library generates RFC4122 compatible random-based (version 4)
UUIDs using data from /dev/(u)random. The uuidgen(2) syscall is also
supported on BSD system. `struct tt_uuid` redefined from RFC4122.
Complimentary functions rewrotten to remove dependecy on e2fs libuuid.
Lua bindings refactored to use new library and support all features.

Closes #317

* Move building of modules into Lua (in rpmspec)
* Remove tarantool.cfg and init.d/tarantool_box from SCL spec (bug in cmake28-epel-6-x86_64)
* Merge two specs (for EL and other RPM linuxes)
* Add Fedora's Mock specifications

  * extra/rpm/tarantool-scl.rpm.spec - SCL spec for 1.5
  * extra/rpm/tarantool-el.rpm.spec.in - Enetrprise Linux 5/6 Specification
  * extra/rpm/tarantool.rpm.spec.in - Specification for other Linuxs
- Build (tarantool-el.rpm.spec and tarantool.rpm.spec) with `--define 'scl 15'`for SCL build.
- Preserve old spec (for compatibility)
- Add dependencies into Specifications, two specs for Mock.
- Create configuration files for Mock builds for EL-{5,6}-{i386,x86_64}

  Working with Mock:
    cmake .
    make new_rpm{_el,}_src
    mock -r <config> --init
    mock -r <config> --rebuild <path_to_srpm>

Bring source package and revision control ignore files up to
date with the state of the master branch.

Change cmake minimum required version to 2.8.

Use copy_directory for Sophia and LuaJIT, this should
fix stupid errors when rebuilding after a pull.
Exclude src/trivia/config.h from source install.

* Remove a bogus message at the start of FindLibUUID.cmake.
* Move cluster_add_node to cluster.
* Extract UUID API into a (potentially) platform-independnent header
  tt_uuid.
* Add error codes for error messages used in UUID generation,
  triggers and consistency checks.
* Cleanup.

Update mans, docs.

A lot of resources still need to be updated (build scripts, etc).

CMake is shipped with broken PosgreSQL script in most distros.
I had to copy this script and patch it to properly support
new versions of PostgreSQL.

 * Install *.lua modules into ${DATADIR}/tarantool/1.5
    and *.so modules into ${LIBDIR}/tarantool/1.5
 * Fix default package.path and package.cpath
 * Install Lua headers to ${INCLUDE_DIR}/tarantool/1.5
 * Install config.h to ${INCLUDE_DIR}/tarantool/1.5
 * Add a new package - tarantool-dev (server development headers)
 * Use RPM Macroses in rpm.spec
 * Fix tarball generation for Debian
 * Use GNUInstallDirs.cmake to setup directories

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