mt_codepage implements code pages 874/932/936/949/950/1250-1258 from
Microsoft's bestfit<cp>.txt sources (script/gen_codepage_tables.py,
SHA-256 pinned). Win32Crt's MultiByteToWideChar/WideCharToMultiByte/
IsDBCSLeadByteEx and net/text_codec use it, so the Android API 24 build
no longer depends on iconv. port.codepage checks every table against
its source file.
