Bolt db crashes when wallet database size is getting close to 250mb. At that point, it's unable to open wallet because the allocated app memory cannot handle that. The crash usually starts from when the wallet is fetching headers and the wallet db rises to the size which the app's allocated memory cannot handle.

this issues was faced during dcrandroid and dcrios days planetdecred/dcrandroid#222

issue was later moved to dcrlibwallet
planetdecred/dcrlibwallet#39

the wallet database interface was exposed to allow the client choose the db driver to be used
decred/dcrwallet#1282

a fix was patched on dcrios by using badgerdb instead of bolt db
https://github.com/planetdecred/dcrios/pull/742/files

we can also do a check for when the user's disk space is low, to prevent that error from badger
planetdecred/dcrandroid#607
