Now that VCS repos are provided in the source array, it becomes too
complicated to have automatic updating pkgver as was the case with
the old VCS PKGBUILDs (there can be multiple repos of different types
in the source array, the VCS repo may not be the package primary
source, etc).

Instead provide an optional way for a PKGBUILD to update the pkgver
value through the specifing of a pkgver() function that returns the
new version string. This is run after all source files are downloaded
so can access the VCS repo if needed.
