* Unbreak OTA on crappy shells
Very, very old ash versions abort on set -o failures (as mandated by
POSIX, granted). This makes it impossible to reliably catch failures in
a single step.
So do it from the Lua side instead.
Should fix#5844
* Launch the zsync wrapper through bash on Cervantes
* Also remove the temporary files when doing a full retry
* Bump base
Pickup the required zsync2/FBInk updates
(https://github.com/koreader/koreader-base/pull/1038)
* Actually does what it says on the tin for Abort
i.e., cleanup temporary files
* On zsync delta failure, offer to retry OTA update with a full download
Fix#4429
* Bring the "this may take a while" popup back up before full DL
Don't rebuild the local tarball for a full dl, we're ignoring it anyway
;)
