Typos visible in the code, and the documentation generated from it

[eero-t]

Running spell checker on the code, shows quite a few spelling issues:

$ codespell --ignore-words-list pEvents  --skip third_party | cut -d: -f3- | sort | uniq -c | sort -nr
     20  Freqency ==> Frequency
     20  configurating ==> configuring
      6  unkown ==> unknown
      4  Heterogenous ==> Heterogeneous
      4  enqueing ==> enqueuing
      4  arugment ==> argument
      3  discription ==> description
      3  compatability ==> compatibility
      2  typicall ==> typically, typical
      2  temporaly ==> temporary, temporarily, temporally
      2  Supportted ==> Supported
      2  pysical ==> physical
      2  programing ==> programming
      2  non-existant ==> non-existent
      2  Minumum ==> Minimum
      2  iamge ==> image
      2  guarentee ==> guarantee
      2  gaurantee ==> guarantee
      2  garanteed ==> guaranteed
      2  extention ==> extension
      2  explictly ==> explicitly
      2  enusre ==> ensure
      2  contols ==> controls
      2  arrary ==> array
      2  Aligment ==> Alignment
      1  substitues ==> substitutes
      1  retreive ==> retrieve
      1  retreived ==> retrieved
      1  reenabled ==> re-enabled
      1  Pluse ==> Pulse, Plus
      1  overide ==> override
      1  Implemeneted ==> Implemented
      1  genrate ==> generate
      1  exeuction ==> execution
      1  defintion ==> definition
      1  decending ==> descending
      1  ablity ==> ability

After these are fixed, I would suggest adding CI test that does similar codespell run.

PS. I did above in Fedora, but codespell is available on all major distros, e.g: https://packages.ubuntu.com/source/noble/codespell
