This PR splits the GUI source files from the core source files. The immediate goal is to allow the CLI to require only a minimum number of dynamic libraries. The long term goal is to create an architectural boundary around the core module, in preparation of libkdbx.
* Fix broken build when using system zxcvbn
Fixup of zxcvbn include statement added in 5513ff5. A zxcvbn/ directory
prefix breaks building with system zxcvbn. Remove this prefix to align
this include statement with ones present in other files. Add zxcvbn
libraries as dependency to CliTest.
* Move src/zxcvbn/ to src/thirdparty/zxcvbn
* Allow for multiple vendor ID's to be checked at once. This allows for the use of one tracking index, streamlining KPXC code.
* Remove support for libusb 0.x on Linux
* Better handling of USB errors during initial key query. Output warnings to console.
