Can you provide me the detail data dictionary of level db and block data? #12975

<!-- This issue tracker is only for technical issues related to Bitcoin Core. This is not a issue ,just a apply! Thanks. <!-- Describe the issue -->

      I want to  get all transactions of all addresses, but bitcoind client is not  support this issue!

So I need to parse all the /blocks/blk????.dat 、/blocks/rev????.dat 、/blocks/index/????.ldb、 /chainstate/???.ldb, but I can't get all data structure from Bitcoin official website！

1、when parse /blocks/index/????.ldb files，where the key startwith 'b', the value always startwith '88' the offical description is : 'b' + 32-byte block hash -> block index record. Each record stores: * The block header * The height. * The number of transactions. * To what extent this block is validated. * In which file, and where in that file, the block data is stored. * In which file, and where in that file, the undo data is stored.

but the source file chain.h is: <pre><code> inline void SerializationOp(Stream& s, Operation ser_action, int nType, int nVersion) { if (!(nType & SER_GETHASH)) READWRITE(VARINT(nVersion)); READWRITE(VARINT(nHeight)); READWRITE(VARINT(nStatus)); READWRITE(VARINT(nTx)); if (nStatus & (BLOCK_HAVE_DATA | BLOCK_HAVE_UNDO)) READWRITE(VARINT(nFile)); if (nStatus & BLOCK_HAVE_DATA) READWRITE(VARINT(nDataPos)); if (nStatus & BLOCK_HAVE_UNDO) READWRITE(VARINT(nUndoPos));

    // block header
    READWRITE(this->nVersion);
    READWRITE(hashPrev);
    READWRITE(hashMerkleRoot);
    READWRITE(nTime);
    READWRITE(nBits);
    READWRITE(nNonce);
}

</pre></code> The front field is nVersion, but it is match with the index file(/blocks/index/????.ldb) Also I can not understand the code meaning if (!(nType & SER_GETHASH)) READWRITE(VARINT(nVersion));

2、when i parse blk01116.dat （but the blk00000.dat file is normal!） Substring the hex data:

<!--- What behavior did you expect? -->

I want to know the detail of local block info。

Thanks！！！！
