pip/libs/main/text/pistring.cpp
peri4 caa7880cc4 get rid of piForeach 
apply some code analyzer recommendations
ICU flag now check if libicu exists
prepare for more accurate growth of containers (limited PoT, then constantly increase size)

//! String is a sequence of \a PIChar. Real memory size of string is symbols count * 2.
//! String can be constucted from many types of data and can be converted
//! to many types. There are many operators and handly functions to use
//! string as you wish.

//! Строка состоит из последовательности \a PIChar. Реальный объем памяти,

//! создана из множества типов и преобразована в несколько типов.
//! Имеет множество методов для манипуляций.
