[gentoo-dev] [PATCH] bzr.eclass: Drop bzr_bootstrap and bzr_src_prepare.

[Ulrich Müller]

No ebuild in the Gentoo repository uses the bzr_bootstrap
functionality. Therefore drop the function along with bzr_src_prepare
(which would not have worked in EAPI 6 anyway, due to missing call to
eapply_user). After this change, inheriting eutils is not needed any
more.

Drop support for EAPIs 0 and 1 for further simplification.
---

This is to be applied on top of the patch posted earlier today.

We could go for bzr-r1.eclass instead. However, the functionality
associated with EBZR_PATCHES and EBZR_BOOTSTRAP is not used in the
tree, and overall the eclass is little used. Therefore I think that
applying these changes in-place is acceptable here.
