Jia Tan ee2f483500 Tests: Minor cleanups to OSS-Fuzz files.
Most of these fixes are small typos and tweaks. A few were caused by bad
advice from me. Here is the summary of what is changed:

- Author line edits

- Small comment changes/additions

- Using the return value in the error messages in the fuzz targets'
  coder initialization code

- Removed fuzz_encode_stream.options. This set a max length, which may
  prevent some worthwhile code paths from being properly exercised.

- Removed the max_len option from fuzz_decode_stream.options for the
  same reason as fuzz_encode_stream. The alone decoder fuzz target still
  has this restriction.

- Altered the dictionary contents for fuzz_lzma.dict. Instead of keeping
  the properties static and varying the dictionary size, the properties
  are varied and the dictionary size is kept small. The dictionary size
  doesn't have much impact on the code paths but the properties do.

Closes: https://github.com/tukaani-project/xz/pull/73

Maksym Vatsyk 483bb90eec Tests: Add fuzz_encode_stream ossfuzz target.
This fuzz target handles .xz stream encoding. The first byte of input
is used to dynamically set the preset level in order to increase the
fuzz coverage of complex critical code paths.

Maksym Vatsyk 7ca8c9869d Tests: Add fuzz_decode_alone OSS-Fuzz target
This fuzz target that handles LZMA alone decoding. A new fuzz
dictionary .dict was also created with common LZMA header values to
help speed up the discovery of valid headers.
