[libFuzzer] Improve FuzzedDataProvider helper.

Authored by Dor1s on Jun 14 2019, 11:13 AM.



The following changes are made based on the feedback from Tim King:

  • Removed default template parameters, to have less assumptions.
  • Implemented ConsumeBytesWithTerminator method.
  • Made PickValueInArray method work with initializer_list argument.
  • Got rid of data_type type alias, that was redundant.
  • Refactored ConsumeBytes logic into a private method for better code reuse.
  • Replaced implementation defined unsigned to signed conversion.
  • Fixed ConsumeRandomLengthString to always call shrink_to_fit.
  • Clarified and fixed some commments.
  • Applied clang-format to both the library and the unittest source.

Tested on Linux, Mac, Windows.

Trying rebase, re-running the tests, and committing again.
