mdz_wchar description

mdz_wchar is dynamically-sized contiguous string, containing C wchar_t characters.

Capacity - how many "wide"-characters memory is reserved for.
Size - how many "wide"-characters are actually used in a string, excluding terminating 0.
Length - actual length of string in symbols, excluding terminating 0. "surrogate pairs" count as 1 symbol.
"reserve/AndReserve" functions allocate/reallocate memory dynamically using malloc()/realloc().
"attach" functionality allows attaching contiguous block of memory to string, for using string functions on it.

UTF-16 "surrogate pairs" are supported and checked.
Unicode "combining characters" are not specially-distinguished and counted as distinct symbols.
Endianness of bytes in "wide"-character - is always endianness of platform.
Size of wchar_t in bytes - is compiler-dependend. At the moment, library supports only wchar_t with size of 2 bytes.
