* [vcpkg ci:osx] Remove brew install

* add instructions for creating a new vagrant box

* fix the vagrant scripts for the new box

* finish fixing the setup

* [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)

* [many ports] fix compile with Xcode 12 CLTs

This mostly means fixing errors on implicit-function-declaration,
and removing some Werrors
* alac-decoder
* apr
* argtable2
* arrow
* hyperscan
* mcpp
* minizip
* mosquitto
* stormlib

* [many ports] even more Xcode 12 CLT fixes

* [jxrlib darknet] fix the last ports! (hopefully)

* CRs, plus minor wip changes to osx scripts

* [vcpkg/scripts/pkgconfig] rewrite pkgconfig check for libraries.

* [vcpkg/scripts/pkgconfig] fix more details.

* [vcpkg/scripts/pkgconfig] update to latest test version

* Revert "ws change to check functionallity of script for testing."

This reverts commit 26269e9e776009230777d9390465715f2ebac465.
