* [vcpkg] Add "Homepage" field to the CONTROL files.

* [many ports] Updates 2019.05.08

* Undo changes for failure ports grpc libjpeg-turbo curl cartographer

* [guetzli] Patch to handle breaking changes in butteraugli

* breakpad: Enable building the libbreakpad_client library

That's the library that allows creating and uploading .dmp files
when a program crashes.

Use the same flags and setup as for libbreakpad, just note that
this commit changes the installation folder for headers which
was previously incorrect:
The libbreakpad headers were installed in include/google_breakpad,
but the correct path is include/breakpad/google_breakpad,
and client headers go into include/breakpad/client/windows.

* [breakpad] Install headers one directory higher

* [breakpad] Switch to only build static libraries. Disable libbreakpad_client on non-windows due to additional work required.
