This patch embeds a parser for binary data dumped via the memory
profiler to Tarantool binary.

It is a set of the following Lua modules:
* utils/bufread.lua: read binary data from a file.
* utils/symtab.lua: symbol table decode functions
* memprof/parse.lua: decode the memory profiler event stream
* memprof/humanize.lua: display decoded data in human readable format
* memprof.lua: Lua script and module to display data

It launch with the following command:
$ tarantool -e 'require("memprof")(arg[1])' - filename.bin

Closed #5490
