* Update WPILib to allow OpenCV 4 support
The existing version only supported OpenCV 3, OpenCV 4 support has been added recently
* Update wpilib port to allow opencv4
Was only compatible with opencv3, and would fail to build with 4.
Also had to update to include eigen, since we now depend on that as well

Use https://ftp.pcre.org/pub/pcre/ instead
* [pcre] Fix typo in Description of CONTROL file
Before this change, `lhs == rhs` missed the check for
`lhs.size() == rhs.size()`, and then did a `memcmp` on the buffers up to
`lhs.size()`. This means that, if `lhs.size() < rhs.size()`, it would
allow two unequal strings to compare equal if, up to `lhs.size()` they
are the same; and if `lhs.size() > rhs.size()`, then it would read out
of bounds.
