Added build + test jobs in GitLab-CI and build + test + deploy jobs on
Travis-CI for Fedora 31.

Updated testing dependencies in the RPM spec to follow the new Python 2
package naming scheme that was introduced in Fedora 31: it uses
python2-' prefix rather then 'python-'.

Fedora 31 does not provide python2-gevent and python2-greenlet packages,
so they were pushed to https://packagecloud.io/packpack/backports
repository. This repository is enabled in our build image
(packpack/packpack:fedora-31) by default. Those dependencies are build-time,
so nothing was changed for a user. The source RPM packages were gathered
from https://rpms.remirepo.net/rpmphp/

Added build + test jobs in GitLab-CI and build + test + deploy jobs on
Travis-CI for CentOS 8.

Updated testing dependencies in the RPM spec to follow the new Python 2
package naming scheme that was introduced in CentOS 8: it uses
'python2-' prefix rather then 'python-'.

CentOS 8 does not provide python2-gevent and python2-greenlet packages,
so they were pushed to https://packagecloud.io/packpack/backports
repository. This repository is enabled in our build image
(packpack/packpack:el-8) by default. Those dependencies are build-time,
so nothing was changed for a user. The source RPM packages were gathered
from https://cbs.centos.org

.

Disabled app-tap/pwd.test.lua on CentOS 8 due to systemd-nss issue,
which was not worked around properly. Filed #4592 to resolved it in the
future.

Eliminated libunwind runtime dependency (and libunwind-devel build
dependency) on CentOS 8, because the base system does not provide it.
fiber.info() backtraces and printing of a backtrace after a crash will
not be available on this system. Hopefully we'll fix it in the future,
filed #4611 on this.

Closes #4543

After we started using bundled version of libyaml by default (see commit
47b91e90), we can remove it from
building dependencies for RPM and DEB packages.

Hold libcurl-7.65.3. This version is not affected by the following
issues:

* #4180 ('httpc: redirects are broken with libcurl-7.30 and older');
* #4389 ('libcurl memory leak');
* #4397 ('HTTPS seem to be unstable').

After this patch libcurl will be statically linked when
ENABLE_BUNDLED_LIBCURL option is set. This option is set by default.

Closes #4318

@TarantoolBot document
Title: Tarantool dependency list was changed

* Added build dependencies: autoconf, automake, libtool, zlib-devel
  (zlib1g-dev on Debian).
* Added runtime dependencies: zlib (zlib1g on Debian).
* Removed build dependencies: libcurl-devel (libcurl4-openssl-dev on
  Debian).
* Removed runtime dependencies: curl.

The reason is that now we use compiled-in libcurl: so we don't depend on
a system libcurl, but inherit its dependencies.

After we fixed bundled libyaml to correctly print 4-byte Unicode
characters, it is no longer compatible with the upstream version, so
enable building with bundled libyaml for every platform.
This way the tests will pass.

Follow-up #4090

Added --force flag to travis-ci jobs not to stop on failed tests.
Due to any found failed test breaks the testing it masks the other
fails and in the following ways it's not good:
- flaky test masks real problem
- release testing needs overall result to fix it fast
- parallel testing may produce flaky test

Close: #4131

This reverts commit c2de45c4.

Not needed anymore as the DDL bug it was supposed to work around has
been finally fixed.

Follow-up #3420

Until the bug in #3420 is fixed

The -j -1 used to legacy consistent mode. Reducing the number of jobs
to one by switching to -j 1, uses same part of the code as in parallel
mode. The code in parallel mode kills hung tests.

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.

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/ '\'.

Sophia was an experimental storage engine in 1.6.x.
Please use 'vinyl' engine in Tarantool 1.7 instead.
