This allows us to use function/variable/class attributes to specify locking
requisites, allowing problems to be detected during static analysis.
This works perfectly with newer Clang versions (tested with 3.3-3.7). For older
versions (tested 3.2), it compiles fine but spews lots of false-positives.
New, undocumented-on-purpose -mocktime=timestamp command-line
argument to startup with mocktime set. Needed because
time-related blockchain sanity checks are done on startup, before a
test has a chance to make a setmocktime RPC call.
And changed the setmocktime RPC call so calling it will not result in
currently connected peers being disconnected due to inactivity timeouts.
Prevents stomping on debug logs in datadirs that are locked by other
instances and lost parameter interaction messages that can get wiped by
ShrinkDebugFile().
The log is now opened explicitly and all emitted messages are buffered
until this open occurs. The version message and log cut have also been
moved to the earliest possible sensible location.
Simplify and make the code in AppInit2 more clear.
This provides a straightforward flow, gets rid of .count() (which makes
it possible to override an earlier provided proxy option to nothing), as
well as comments the different cases.
Instead of only checking height to decide whether to disable script checks,
actually check whether a block is an ancestor of a checkpoint, up to which
headers have been validated. This means that we don't have to prevent
accepting a side branch anymore - it will be safe, just less fast to
do.
We still need to prevent being fed a multitude of low-difficulty headers
filling up our memory. The mechanism for that is unchanged for now: once
a checkpoint is reached with headers, no headers chain branching off before
that point are allowed anymore.
Accept strings containing decimal values, in addition to bare values.
Useful from JSON-RPC implementations where it's not possible to have
direct control over the text of numbers (e.g. where numbers are always
doubles), and it's still desired to send an exact value.
This would allow users to post JSON content with numbers encoded like
`{"value": "0.00000001"}` instead of `{"value": 0.00000001}` which some
php/python encoders wrap into 1e-8, or worse.
Since unspendable outputs can't be spent, there is no threshold at which it would be uneconomic to spend them.
This primarily targets transaction outputs with `OP_RETURN`.

Changes:
- cherry-picked on top of bitcoin:master
- added RPC test for fundrawtransaction
I've never liked the chain-specific exception to having to set a
password. It gives issues with #6388 which makes it valid to
set no password in every case (as it enables random cookie authentication).
This pull removes the flag, so that all chains are regarded the same.
It also removes the username==password test, which doesn't provide any
substantial extra security.
