RPCs in blockchain.cpp were returning misleading or incorrect error
codes (for example getblock() returning RPC_INTERNAL_ERROR when the
block had been pruned). This commit fixes those error codes:
- RPC_INTERNAL_ERROR should not be returned for application-level
errors, only for genuine internal errors such as corrupted data.
- RPC_METHOD_NOT_FOUND should not be returned in response to a
JSON request for an existing method.
Those error codes have been replaced with RPC_MISC_ERROR or
RPC_INVALID_PARAMETER as appropriate.
"startingpriority" and "currentpriority" are no longer returned in the JSON information about a mempool entry. This affects getmempoolancestors, getmempooldescendants, getmempooolentry, and getrawmempool.
In spite of the name FindLatestBefore used std::lower_bound to try
to find the earliest block with a nTime greater or equal to the
the requested value. But lower_bound uses bisection and requires
the input to be ordered with respect to the comparison operation.
Block times are not well ordered.
I don't know what lower_bound is permitted to do when the data
is not sufficiently ordered, but it's probably not good.
(I could construct an implementation which would infinite loop...)
To resolve the issue this commit introduces a maximum-so-far to the
block indexes and searches that.
For clarity the function is renamed to reflect what it actually does.
An issue that remains is that there is no grace period in importmulti:
If a address is created at time T and a send is immediately broadcast
and included by a miner with a slow clock there may not yet have been
any block with at least time T.
The normal rescan has a grace period of 7200 seconds, but importmulti
does not.

The meaning is clear from the context, and we're inconsistent here.
Also save typing when using named arguments.
- `bitcoinaddress` -> `address`
- `bitcoinprivkey` -> `privkey`
- `bitcoinpubkey` -> `pubkey`
There were discrepancies between usage of "block chain" and "blockchain", I've changed them to the latter. The reason for this was that Wikipedia when describing this data structure writes "A blockchain — *originally block chain*", so it seemed the more appropriate term.

waitfornewblock waits until a new block is received, or the timeout expires, then
returns the current block height/hash.
waitforblock waits for a specific blockhash, or until the timeout expires, then
returns the current block height/hash. If the target blockhash is the current
tip, it will return immediately.
waitforblockheight waits until the tip has reached a certain height or higher,
then returns the current height and hash.
waitforblockheight is used to avoid polling in the rpc tests.
The key (transaction id for the following outputs) should be serialized
to the HashWriter.
This is a problem as it means different transactions in the same
position with the same outputs will potentially result in the same hash.
Fixes primary concern of #7758.
Add a method Cursor() to CCoinsView that returns a cursor which can be
used to iterate over the whole UTXO set.
- rpc: Change gettxoutsetinfo to use new Cursor method
- txdb: Remove GetStats method - Now that GetStats is implemented in
terms of Cursor, remove it.
We can't change "softforks", but it seems far more logical to use tags
in an object rather than using an "id" field in an array.
For example, to get the csv status before, you need to iterate the
array to find the entry with 'id' field equal to "csv":
jq '.bip9_softforks | map(select(.id == "csv"))[] | .status'
Now:
jq '.bip9_softforks.csv.status'
There is no issue with fork names being incompatible with JSON tags,
since we're selecting them ourselves.

Split out methods to every module, apart from 'help' and 'stop' which
are implemented in rpcserver.cpp itself.
- This makes it easier to add or remove RPC commands - no longer everything that includes
rpcserver.h has to be rebuilt when there's a change there.
- Cleans up `rpc/server.h` by getting rid of the huge cluttered list of function definitions.
- Removes most of the bitcoin-specific code from rpcserver.cpp and .h.
Continues #7307 for the non-wallet.
