"qsort implementation fails to sort arrays greater 4GB"

Bug#712447 "Valgrind reports use of not initialized memory
after 'reload configuration'

Bug#695689 "'save snapshot' does not report error when it occurs"

Bug#686411 "Possible data loss when renaming a snapshot"

Document the coding style in use. Quote Linux Kernel
coding style as the basis. Add Tarantool-specific
extensions.

Add a pre-recorded snapshot to the test coverage,
one that contains 500 records. Verify that we can start
from it.

Rename a test file to avoid shell escapes, align
a comment, modify ./test-run defaults to follow
the new build layout.

Generalize CMake build scripts to be able to
easily add new modules (such as box or feeder).
Move prscfg.{h,c} (confetti general library and
header) from third_party/confetti/ to cfg/ to
simplify the build.
Update configuration file templates and parsing
code to use the new confetti.
Rename cfg/tarantool_cfg.h to cfg/warning.h,
to be able to reuse it in warning.c.
Update tests.

Note: tarantool_feeder is now built in mod/feeder;
tarantool_silverbox is built in mod/silverbox.
Modify .gitignore accordingly.

Addition of required configuration file options broke backward compatibility
(https://bugs.launchpad.net/bugs/708685)

Use the new version of confetti that allows to determine whether array element
is initialized.

Specify the type of op_code parameter of UPDATE
operation.

Test runner: improve cleanup when installing a new server
(remove more old stuff).
Do not leave around a .reject file if there are valgrind
errors only (it's useless).

Update help messages, add comments, add more checks,
fix minor bugs.

A post-push fix for Bug#712456, use namespace_count
instead of nelem(namespace) to find out the number
of pre-allocated namespaces, 'namespace' is a pointer
after all.

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.
