2. delete setopt and delimiter contractions

2. delete setopt and delimiter contractions

Store the information about spaces in a pre-recreated
system space.

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

Remove space configuration from confetti.
Use transaction and space triggers to run post-DML
actions to perform DDL changes.

Implement a Lua FFI binding to disable tests.

Temporarily disable space-loading code in tarancheck
and tarantar (this breaks them).

Mostly all tests are broken.
Memcached is disabled (non-functional).

Integrate libyaml instead of internal yaml formaters.

changelog:
* fixed i64 convertion bug
* refactored bindings to new admin .info() scheme
* moved lua plugin api to separate file
* moved lua fiber api to separate file
* slab binding refactored
* added fiber lua bindings
* rewriten admin reply handler
* proper yaml end-of-document formater
* proper server error formater
* fixed bug with leftover data on stack on exception error
* added support of i64 types to lyyaml
* removed couple of box.show_ bindings
* console client fixes to support new scheme

This push has a yet broken test's.

2. Make support of multiline delimiters

Little refactoring +xlog, +snap, snapshot->snap

Thanks for Anatol Pomozov

* 	Implementing LUA printer (https://blueprints.launchpad.net/tarantool/+spec/tc-lua-printer)
* 	Moving xlog printer code into tc_print_xlog.{c,h}, leaving basic printing code in tc_print.{c,h}.
* 	Fix TC bug (https://bugs.launchpad.net/tarantool/+bug/1185746), Added support for snap print formatters.
* 	Added temporary workaround for option (-B or --bin), that allow you to print STR instead of INT and INT64 in lua formatter.
	Works in "keys" and UPDATE (ASSIGN or INSERT).
*	Fix of stdin: add custom function for pipe instead of stdin (very slow with readline)
*	Fix for realloc problems
	1) 	if size is 0, then behaviour is undefined
	2) 	in C99 if realloc returns NULL, and size is not zero (errno == ENOMEM) input buffer of memory is needed to be freed manually.
		Whitepaper of POSIX standart:
		http://pubs.opengroup.org/onlinepubs/9699919799/functions/realloc.html
*	Add support of -D (--delim) argument, that sets delimiter on start of tarantool client.
	Also, if you "cat" .snap or .xlog files in LUA format it prints delim in end of every coomand.
