Commit Message

Limit exponent range in number parsing.

Reported by XmiliaH.

(cherry-picked from commit e56048753)

When parsing exponent powers greater than (1 << 16) * 10 == (65536 *
10), the exponent values are cut without handling any values greater.
This patch fixes the behaviour, but restricts the power maximum value by
`STRSCAN_MAXEXP` (1 << 20).

Sergey Kaplun:
* added the description and the test for the problem

Part of tarantool/tarantool#9145
