* switch to another fuzzer repo aimed to be merged upstream
* update email addresses
checked with arvid, he approved adding his address
* [libtorrent] improve building
- use ninja
- don't build tests
- respect CXXFLAGS when building boost
- less verbose output when downloading
* create initial corpus zip files from git
this makes it much easier to add and remove
both fuzzers and corpus upstream and make
sure they work well.
