Encapsulate trigger management, as well as undo managemnt
specific to memtx in the engine. Fix a potential memory leak
in MemtxEngine::rollbackStatement(), with wrong reference counting
for rolled back tuple.

Always generate redo record, even in wal_off=true mode, this
simplifies txn_commit().

*) fixed several comments and minor bugs
*) after CR fixes

Update comments, rename matras_extents_count() to matras_extent_count().

Provide access to iproto sync via session.sync() binding.

The value is valid only at start of a Lua call before the first yield,
after which it may be replaced with a sync from another request
running on the same session.

+ Check Lua types for uint/decode for msgpack(ffi)/json/yaml tests

Include all neede variables to tarantool.h

tarantool.h is an external header (perhaps), so not available with
plain #include ""

Tell matras table that you're about to change a location
before actually changing it.

This patch adds `src/module.h` header file with definition of all public
API functions suitable to use in Lua/C modules for Tarantool. This header
is automatically generated from src/*.h by CMake (`make generate_module_api`)
by extracting code blocks between /** \cond public */ /* \endcond public */
Doxygen-style comments.

Definitions of functions in module.h are frozen and must not be changed by
future commits/releases. A new test case `app/module_api` is added to check
compilation, linkage and loading of Lua modules and functionality of
provided API functions.

Other changes:

 * Convert mysql and pg to use module.h and prepare to convert to .c
 * Fix includes in say.h, coeio.h
 * Rename luaL_pushnumber64 to luaL_pushuint64 and
          luaL_pushinumber64 to luaL_pushint64
 * Add LUA_API macros to public luaL_* functions (actually adds extern "C")
