Fix a bug in show fiber output (it's used
to not print out carriage return, and that
drove the test tool mad).

Use CMake to:
- Compile tarantool_silverbox, tarantool_feeder.
- enable ./test-run testing out-of-source
- implement Debug/Release configurations
- add ENABLE_BACKTRACE ENABLE_TRACE and HAVE_BFD switches
- support auto-generated targets

Add 'reload configuration' to the list of administrative
commands of tarantool command line client.

Colored client prompt didn't work well with
readline history feature. Remove the lame
implementation of prompt color.

Change double quotes to single quotes for string
constants. In ANSI SQL double quotes are used
to quote identifiers, not constants. I used
double quotes initially since they are allowed
in MySQL.

Rename check_config to check-config.
Update option help message.

Test runner: extend test coverage. Allow non-positive
numbers in the grammar.

Add basic support for UPDATE SQL statement.
Simplify code.

Implement and test a basic DELETE sql command.

Test-runner: fix a typo in a help message (test-run.py)

Do not try to start gdb if do not know how to do it.

Implement test-runner options that allows to put vardir in /dev/shm.

Test runner: use spaces to align test results.

Implement a basic SQL parser.

Implement SQL statements: INSERT, UPDATE, DELETE,
PING.

Add a test case that tests INSERT/SELECT/DELETE.

Other changes:

Remove support for result-prefix from admin.py
Rename admin.py to tarantool (tarantool client).
Add readline support to tarantool client.
Make sql.g and sql.py independent from yapps
Add gdb support to ./test-run
Disable all optimizations when compiling with DEBUG.
Fix a few bugs discovered by trial and error in silverbox
protocol description.
Add automatic reconnection in case of server disconnect
to test connections. This is used to automatically
reconnect to the server after server restart or reinstall.
Implement soft and hard (with and without removal of vardir)
server restart.
Make show.test results independent from other tests (data I/O
skews statistics, and there is no way to reset it without
restarting the server).
Add  TCP_NODELAY to fiber sockets.
