Spelling corrections for src directory

Spelling corrections as found by codespell and in #561.

Some reported problems were already fixed, others are fixed here, with some exceptions (a,o.):
- "referenceby" in defgen.cpp as this is in the output and I cannot oversee the consequences (looks like none, but ...)
- "HANGEUL_CHARSET" left as is as in some MS documentation is written: 'HANGUL_CHARSET: Also spelled "Hangeul". Specifies the Hangul Korean character set.' (https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-wmf/0d0b32ac-a836-4bd2-a112-b6000a1b4fc9).
