Add provisioning for user type.
Support user type in alter.
Do not return roles in user_by_name().
Make it possible to grant privileges on roles ('execute').

Add a owner for a user, use owner privileges to check
whether or not it's possible to drop a user.

Rebuild empty.snap, it can be used as bootstrap.snap to
fill the schema from scratch.

Update bootstrap.snap with an index on _user[2] (second
field in _user).

t chec  # On branch stable

* 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>

  Merging commits

* New brewspec, that gives ability to build latest stable
  (for latest master you need to pass '--devel' flag)
* All dependencies are inside this spec
* We can now test Tarantool (you need to pass '--with-tests'
  flag to 'brew')
* We can build Tarantool with -DCMAKE_BUILD_TYPE=Debug (default is
  'Release')
* Fix for name of pypi module - ('python-daemon', not 'daemon')
* Fix README for MacOSX

doc/{branch}/... -> doc/...
Master/Stable -> One-page/Multi-page

Update mans, docs.

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

 * 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

Add new system spaces _user and _priv to store users,
their passwords and their privileges.
Implement an authentication request in iproto protocol

Add a system space _func to store presistent information
about Lua functions. A function is now a subject
to ownership and privilege control.

Use MySQL-style sha1-double-hashing authentication by default.

Implement new Lua functions:

box.session.su()
box.session.uid()
box.schema.user.create()
box.schema.user.drop()
box.schema.user.grant()
box.schema.user.revoke()
box.schema.func.create()
box.schema.func.drop()

Store space creator in space definition.

What this patch doesn't implement:

- privilege checks in replication
- authentication of replication slaves
- exhaustive test coverage
