@todo: Deal with this:

/build/buildd/binutils-2.20.1/builddir-single/bfd/../../bfd/plugin.c:127:
warning: Using 'dlopen' in statically linked applications requires

libltbox.a(tarantool.c.o): In function `main':

Implement
https://blueprints.launchpad.net/tarantool/+spec/consistent-header-guards

Audit all header files in tarantool code base for consistent use
of header guards:
- consistent naming scheme, following doc/coding-style.txt
- header guard goes before the copyright
- each header is self-sufficient.
- add copyright headers where they were missing.

Remove __packed__, __unused__, __noinline__ and __regparm2__ from util.h,
since the name __unused__ conflicted with a parameter name in
third_party/valgrind/valrgind.h, which led to a dependency in inclusion
order between util.h and this header. The define names were not standard, I
couldn't come up with some meaningful and standard names, and they were only
saving some typing, while not providing any extra functionality.

Rename 'silverbox' to 'box', across the board.
Delete the remnants of the old build system
(scripts/rules.mk and scripts/config-def.mk).

Do not touch client/perl for now, since it's maintained
elsewhere.

Add the simplest CPack configuration for
'make package' and 'make package_source'
targets.
Add an empty snapshot to revision control
to use in 'make package' and thus
spare the user from the need to do
--init-storage.
Modify args.test to accept a bare
(no git version) version number, and thus
ensure the user from a yet another call before
he/she can start work/play around.

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.

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

	chkconfig -> check_config
	mod_reloadconfig -> mod_reload_config

	* Enable statistic collection.
	* Add counter of expire rate.

	add chkconfig
	add 'reload configuration' command for admin console

[box] [client] [perl] Fix _validate_params() not to clobber a param. Fix update/splice for compatiblity with older perls.
