[PATCH 00/13] sql: support -2^63 .. 2^64-1 integer type

[Stanislav Zudin <szudin@tarantool.org>]

The patch enables support of big integers in the range [2^63, 2^64-1].
Conversion functions use return value to inform about value
they return - signed integer in the range [-2^63,2^63-1] or 
unsigned integer in the range [2^63, 2^64 -1].
The changes affect sql processing, VDBE, arithmetic functions and
aggregate functions.
