There's no need to maintain an old version. Removed all patches as they are all upstream. Import new ones from Arch, Debian, and OpenEmbedded. Signed-off-by: Rosen Penev <rosenp@gmail.com>

Subject: [PATCH] Fix libc++ compatibility by renaming atomic_init API
|
|
|
|
db5 does not build because it is redefining a C++11 standard
|
|
library identifier, atomic_init(). Therefore prefix all
|
|
its internal defines with '__db_', to avoid collisions.
|
|
|
|
Upstream-Status: Inappropriate [as far as open source community is concerned, upstream is dead]
