Merge #11041: Add LookupBlockIndex

Browse Source 
92fabcd44 Add LookupBlockIndex function (João Barbosa)
43a32b739 Add missing cs_lock in CreateWalletFromFile (João Barbosa)
f814a3e8f Fix cs_main lock in LoadExternalBlockFile (João Barbosa)
c651df8b3 Lock cs_main while loading block index in AppInitMain (João Barbosa)
02de6a6bc Assert cs_main is held when accessing mapBlockIndex (João Barbosa)

Pull request description:

  Replace all `mapBlockIndex` lookups with the new `LookupBlockIndex()`. In some cases it avoids a second lookup.
