* [vcpkg ci:osx] Remove brew install
* add instructions for creating a new vagrant box

* [mecab jxrlib] fix ports for CI
mecab needed to use an actual ref that wasn't master,
and jxrlib needed a patch for xcode 12 CLTs.
Additionally, this fixes the mecab version to be a date, the date of the last commit,
since `1.0` is not the correct version (mecab doesn't have released versions)

This mostly means fixing errors on implicit-function-declaration,
and removing some Werrors

* argtable2
* arrow
* hyperscan
* mcpp
* minizip
* mosquitto
* stormlib
* [many ports] even more Xcode 12 CLT fixes
