Move memcached to src/
Make iproto.m dependend on box/*, not vice versa.
Remove box_ prefixes from test suite names.
Initialize networking outside of box/.

This makes Box a step closer to being just a storage
layer for Tarantool.

Still some ugly deps since box/ continues to manage
local hot standby and memcached expire (todo: move it out).

(https://blueprints.launchpad.net/tarantool/+spec/lua-builtin-size-of-subtree)

next_equal and prev_equal for lua box.index was added.

Spelling fixes in the error message file.

Add more information to the error when key cardinality
doesn't match index cardinality in exact match.

Avoid server start/stop in box_big/hash.test (ugly,
but until we have named/dynamic spaces, which are already in the
pipeline, we should not make our test procedure slower).

Rename multipart-pk.test to tree_pk_multipar.test:
consistently use underscores, not dashes, in file
names.

(Unrelated) Recycle more error codes.

Make keyValue an inline function to save a few CPU cycles.

Avoid creation of an extra table in box.lua just to find out
variable list array cardinality.

Revert changes to box.update():
a) they break backward compatibility

This reason alone should be sufficient. There must be no changes
which break backward compatibility in a stable release, unless
it's a fix for a crashing/security bug.

box.update() changes got to be done in a separate task,
and should not break backward compatibility.

Leave update_ol for now, to test multi-part primary key updates,
even though the function itself is quite heavy, hardly something
we can recommend while running Lua procedures in production.

This reverts commit 8dc70aac.

Multipart primary key implementation was added. DELETE and UPDATE commands was
updated for multipart key supporting.

A fix and a test case for Bu#929654 "
Regression with secondary HASH indexes"

Secodnary HASH indexes where skipped by build_indexes()
when starting from a snapshot.

Add a way to reserve space for as many values as necessary
and enable HASH indexes in build_indexes().

Add a test.

Simplify index_tree_el_compare
Make iterators usable regardless of index type.
Add coverage.

Add more tests.

In iterators over tree indexes, check
that key type matches field type.
Add tests for non-unique multipart keys.

Update output of the python test library
to not print extra trailing '\0' at the
end of error message. Update test results.

Eliminate server start/stop/deploy cycle for blueprint
'tree-primary-key' tests. Move the tests to box_big suite.

Add coverage.

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

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

Fix a bug when Lua transaction was rolled back
twice when Lua procedure was invoked from CALL.

Change the way arguments to and from CALL
statement in the binary protocol are passed:
we used to pass everything from the wire as a single
binary blob. Now every field of the received
tuple is passed in as a separate string argument.

Everything passed back from Lua is converted to a tuple. This
makes CALL response similar to one of SELECT.

Improve box.pack() to convert its argument to integer when
necessary. Add an argument count check to box.pack().
Additionally, now box.pack() can be used to pack
operations of 'UPDATE'.

Use tarantool_lua_tostring() in iov_add_ret():
this function is now used to convert return values to
the binary protocol in box_lua.m. This is necessary
if we try to send boolean or nil over the
binary wire, since Lua C API lua_tostring()
does not convert them.

Add box.lua - a system Lua script
compiled into Tarantool and containing a bunch
of Lua code preloaded at startup.

Populate box.lua with implementation
of basic Lua functions:
box.select(), box.update(), box.replace(),
box.insert() (currently an alias for box.replace()),
box.delete(). They are all wrappers around box.process().

Move box_lua_init() to the beginning of mod_init(),
since Lua in future can be used in recover().

Fix a wrong assumption about the contents
of Lua stack in iov_add_multret().

Update sql.g Python SQL grammar to allow
an empty argumeent list for procedure in CALL
statement.

Add initial documentation on Lua procedures.

Add more Lua tests.

Unrelated: rename INSERT to REPLACE, and UPDATE_FIELDS to
UPDATE.
Remove SELECT_LIMIT, which is not used any more.

the tarantool logger process was changed from tee to cat.

Allow disjunctions in SELECT WHERE clause and LIMIT
clause in SELECT, to be able to cover the problem
reported in Bug#729758.

Fix a bug with prepare_gdb arguments (remove an extra
space in -e option).

Add a simple test for Bug#729758.

The following bugs were reported in the process:

Bug#729789 "Zero limit is treated the same as no limit"
Bug#730593 "Bad data if incomplete tuple"
Bug#730613 "SELECT with a disjunction on multiple keys returns
matching tuples twice"

Implement a number of simple fixes to compile on FreeBSD:
- work correctly with a GCC version that doesn't have
  -Wno-unused-result
- compile even if not GNU libc
- tee doesn't have '--append' option on FreeBSD, use
  the short version ('-a').
- fix a typo in log_io.c, ENOENT, not ENONET.

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"

Implement
https://blueprints.launchpad.net/tarantool/+spec/tarantool-test-runner.

This commit adds an implementation of test running framework
(test-run.py), and a simplistic interactive client for
the administartive console of tarantool (admin.py).

A prototype of the first test suite is added in
directory test/box.

"run" is a convenience symlink to test-run.py.

This commit also adds "make test" goal to the
top-level makefile.
