paramaters use floating point representation.

lua.result was somehow missed in the last commit, add now

https://blueprints.launchpad.net/tarantool/+spec/namespace-to-space

Rename 'namespace' to 'space' everywhere:
in configuration, in implementation, in documentation.

Now that confetti supports it, use boolean for true/false
yes/no config options.
Update the manual accordingly.

Remove auto-generation of tarantool_box_cfg.cfg.
This was intended as a sample configuration
file, but it is no longer syntactically correct,
and thus can not be used.
Besides, there are now semantical rules on top
of the syntax restrictions (e.g. you can't define
memcached_expire on a replica), which also
make the auto-generated config incorrect.

Remove it to not mislead first-time users into
trying it out.

Test enviroment:
  - start/stop server routine was updated.
Tests:
  - fix double start srvers.

* valgrind suppresions update

* core signal handling sigaction -> libev
* suppresion file updated

* test-suite valgrind support

Rename hot_standby back to local_hot_standby. Let's
not break compatibility without a strong need.

Merge replication_source_ipaddr and replication_source_port
to a single variable, replication_source, to be able to
provide a list of sources in future.

Update comments in the configuration file.
Remove custom proc title for replication, use custom_proc_title of
the main process.
Renames.

Blueprint 'Make memcached protocol an alternative, not a replacement':

Blueprint was implemented. Memcached now can work
in presence of RELOAD CONFIGURATION statement, even if it
changes a replica to master or a master to replica.

'memcached' configuration file option was removed.
Instead, two new optinos were added:
- memcached_port - optional, default 0, if set, specifies
which port speaks memcached protocol.
- memcached_expire, boolean, which defines whether or not
we run expire on memcached namespace. If not set,
we simply support the protocol, but ignore TTL and never
expire the keys.

Original memcached test was ported to tarantool testing environment.
cas test was disabled, because tarantool has a non-critical bug (in
concurrent environment cas operation can return 'SERVER_ERROR' instead of
'EXISTS')

Replicator was updated:
 - bind replicator poer strategy was changed.
 - terminate child routine for spawner process during exit was added.
 - handle EPIPE error was added to client handler process.
 - remote_hot_standby was deleted.
 - local_hot_standby was renamed to hot_standby.
 - sender_send_sock function was fixed.
 - I/O event processing in replicator fibers was updated.

Fiber:
 - fiber_io_* functions now public.

Update *.cfg files to newer confetti and comments
in the templates.

Code review: reformat comments.
Add comments to fiber.h.
Use tnt_FiberCancelException solely to cancel fibers.
Fix alignment of fiber_server.
Use newer confetti.

Reverse the try/finally wrapping of some fiber functions
as unnecessary.

Implement
https://blueprints.launchpad.net/tarantool/+spec/feeder-in-core

- replicator was implemented;
- 'box_replication' tests was added top test suite;
- feeder module was removedl;
- tarantool's core file was of UTILITY and STORAGE defines;
- fiber name length was upped to 32 characters;
- .gitignore file was updated.

Explain how to configure a namespace.
Tweak some error messages on the way.

Implement slave-to-master and vise versa propagation through
'configuration reload' admin command.

Update comments in the configuration templates
(spelling errors).

Update auto generated (by confetti) cfg/prscfg.c.

Port tarantool to ObjectiveC.
Implement basic TNTException class and
 TNTFiberException and TNTBoxException subclasses.
Replace longjmp/setjmp with ObjectiveC exceptions.

mod/box: Restructurize request processing in the following way:

	try
		begin
		dispatch
		commit
	catch
		abort

where any error during request processing generate an exception.

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.

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.

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
