Move mod/box/ src/box. Fix broken packages.
Rename tarantool_cpack.cmake to cpack.cmake.

Bug#1046260 CentOS builds: "no debugging symbols found"
Do not strip the binary in rpmbuild.

See http://public.kitware.com/Bug/view.php?id=7435

Fix a race condition between build of bundled luajit and build of
tarantool_lua_info.h.

(Failure to build tarantool_lua_info.m on Debian SID).

Lua tests don't pass though.

gcc interpretation of -fno-inline has changed between 4.6.1 and 4.6.3.

Use -Wno-bitwise-op-parentheses only if the compiler has them.

Do not use bundled libobjc on Darwin.
Refactor cmake scritps: introduce os.cmake, arch.cmake,
compiler.cmake, libobjc.cmake, luajit.cmake.

Remove the hack with building libobjc/luajit as a
dependency on cfg.

Do not specify -ggdb when compiling with clang.

Add -fno-objc-legacy-dispatch and -fobjc-nonfragile-abi
when compiling with CLang on Linux.

Remove -fgnu-runtime when compiling with gcc on Mac.

Many minor cleanups.

"Compilation with extrnal LuaJIT broke with addition of FFI"
is fixed, don't try to compile with external LuaJIT.

This reverts commit 8dc70aac.

(https://blueprints.launchpad.net/tarantool/+spec/compile-with-external-luajit)

modes are added.

Move the cmake check for ObjectiveC compiler to an own
file. Tweak the output a bit.
