[Tarantool-patches] [PATCH v1 0/8] Rework standard function

[Mergen Imeev via Tarantool-patches <tarantool-patches@dev.tarantool.org>]

functions work according to ANSI rules, if it is possible. However, the ANSI
specific syntax for these functions will be presented later.

  sql: refactor ABS() funcion
  sql: refactor CHAR_LENGTH() function
  sql: refactor UPPER() and LOWER() functions
  sql: refactor NULLIF() function
  sql: rework TRIM() function
  sql: rework POSITION() function
