Merge #11041: Add LookupBlockIndex
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. Tree-SHA512: ca31118f028a19721f2191d86f2dd398144d04df345694575a64aeb293be2f85785201480c3c578a0ec99690516205708558c0fd4168b09313378fd4e60a8412
