perl: move CPAN loader wrappers to another namespace

avar · gitster · commit 28654678cff4 · 2018-03-05T10:52:28.000-08:00
Move the Git::Error and Git::Mail::Address wrappers to the Git::LoadCPAN::Loader::* namespace, e.g. Git::LoadCPAN::Error. That module will then either load Error from CPAN (if installed on the OS), or use Git::FromCPAN::Error. When I added the Error wrapper in 20d2a30 ("Makefile: replace perl/Makefile.PL with simple make rules", 2017-12-10) I didn't think about how confusing it would be to have these modules sitting in the same tree as our normal modules. Let's put these all into Git::{Load,From}CPAN::* to clearly distinguish them from the rest. This also makes things a bit less confusing since there was already a Git::Error namespace ever since 8b9150e ("Git.pm: Handle failed commands' output", 2006-06-24).
