[tarantool-patches] [PATCH v2 0/7] sql: store regular identifiers in case-normal form

[Kirill Shcherbatov <kshcherbatov@tarantool.org>]

Perform SQL name normalization: cast name to the upper-case
(via Unicode Character Folding). Casing is locale-dependent
and context-sensitive. The result may be longer or shorter
than the original. For example, ß is converted to SS.
The result is similar to SQL UPPER function.

Performed extensive code refactoring to pass parser instance in
routines that use sql_normalize_name function. This makes
possible to raise an error in case of normalizing failure.

Changes in version 2:
	- Setup parser error externally
