Up to this patch any space had two additional methods
that were methods of ephemeral spaces. In this patch
these methods deleted from vtab and from now on
ephemeral spaces are spaces with special vtab.
Part of #3375.

These patches allow us use ephemeral spaces in Lua. Ephemeral spaces are
special spaces that in most cases work in the same way as usual spaces
(for users), but they do not touch transactions and are local to one Lua
session. The are deleted by GC when there is no references to them. They
can be created and deleted but cannot be altered. Till now they were
used to process some sql queries.

3. I do not think we should track any ephemeral space things in statistics.
Same about rmean in other places.

8. Looks like most of this functions are almost complete
duplicates of ones from index.c. Please, remove duplication.
And move the functions into index.c.

9. Please, reduce the test size. It is really huge and full of
redundancy:
* you do not need to create/drop space to test each statement;
* you do not need to fill each space with 10 records to test only one of them;
* it is not necessary to the same functionality with a set of almost
identical tests like three insertions below.

10. Unused function.
General recommendation: please, try to make .result file be at most 1000 lines.

1. You can pass format as a Lua table into space_new_ephemeral
and encode it inside. It is strange to pass binary data into
Lua function, that does not work with network or disk.

6. It is strange, that space_new_ephemeral returns space *, but
space_delete_ephemeral takes Lua table. Please, make space_delete_ephemeral
taking space * as well.

7. After drop any DML/DQL method should throw an error that the
space is deleted. You can do it via a separate metatable for example.
For example, like this:
dropped_mt = {
__index = function() error('The space is dropped and can not be used') end
}
setmetatable(space, dropped_mt)

9. 'narg' is rather about argument count. Lets better use 'idx' like
in Lua sources. Same about functions below.
10. Kostja asked to describe parameters for Lua C function in the
same way as for internal C functions. So lets describe it somehow
like this:
@param L Lua stack to get space from.
@param idx Index by which to get the space from @a L.
Same about comments of other functions.

16. Not luaL_error. You should rethrow the tarantool error to Lua. See
luaT_error. Same about errors below.

18. This function is almost completely the same as lbox_space_frommap.
Please, remove code duplication.

1. Do you really need this space_id filling? As I understand,
ephemeral space id is always 0, so it was nullified already
in memset above.
2. Please, extract request initialization into separate
functions, that will be called from box_insert and box_ephemeral_insert.
Same for other functions.

3. Insert returns the tuple too, so here temp_result leaks, it is not?
I am not sure, just a question.
4. Lets make this API similar to other box methods: result is mandatory
non-NULL argument.
All the same comments for other functions.

8. Lets better get the pk the same way as in non-ephemeral space:
via index_find_unique. When we will add alter, there are non-unique
indexes too.
9. Lets extract all these DML routines into _impl() functions
and call them from ephemeral and real DML. There are too many code
duplication.

initialization from ephemeral space. It should be NULL or

1. Please, do not make index_def depend on space.
Instead of passing struct space to ephemeral_index_def use
directly field_def * array and field_count parameters.
2. Can you find a way how to do not duplicate this code
from alter.cc index_def_new_from_tuple?

5. Wrong alignment. Rather this:
struct key_part_def *part_def =
(struct key_part_def *) malloc(sizeof(*part_def) * part_count);
6. You can use region here and do not free it now, but later using
region_truncate. It reduces count of malloc-free oscillation.

11. It will not work, when we will allow multiple indexes. You should not
delete and nullify all indexes when a one is deleted.

14. Same as earlier - do not override Tarantool error with Lua one.
Use luaT_error. I will not mention it anymore, so, please, found and
fix other places.

17. It is enough to just print the entire 'i'. Just write it alone on
the line. And it is not necessary to output the entire 'i' on each
'create_index'. Print just the attributes you have specified in the
options.

18. Please, do not use 'uint' and 'str' - they are deprecated.

2. You should not check more than 1 thing to test an error. When
a function can return NULL both on success and on error, you should
move the result into out parameter and return int: 0 on success, -1
on error.

5. Please, see what arguments OutOfMemory takes:
size_t amount, const char *allocator,
const char *object
You should specify here "region_alloc" instead of "region", and
"region_defs" instead of "new slab".
