7d4b5cb gitian: Bump cache dir for 0.11 (Cory Fields)

Change `read_string` to fail when not the entire input has been
consumed. This avoids unexpected, even dangerous behavior (fixes #6223).

The new JSON parser adapted in #6121 also solves this problem so in
master this is a temporary fix, but should be backported to older releases.

Also adds tests for the new behavior.

Until secp256k1 is used for verification there is no reason for Bitcoin
Core's secp256k1 to link against gmp, even if available. Pass a flag to
configure to override the bignum implementation.

This fixes a crash at runtime on ppc64 reported by @gmaxwell.

Previously due to an off-by-one error the wallet ignored
nLockTime-by-height transactions that would be valid in the next block
even though they are accepted into the mempool. The transactions
wouldn't show up until confirmed, nor would they be included in the
unconfirmed balance. Similar to the mempool behavior fix in 665bdd3,
the wallet code was calling IsFinalTx() directly without taking into
account the fact that doing so tells you if the transaction could have
been mined in the *current* block, rather than the next block.

To fix this we strip IsFinalTx() of non-consensus-critical
functionality, removing the default arguments, and add CheckFinalTx() to
check if a transaction will be final in the next block.

8273793 Eliminate compiler warning due to unused variable (Suhas Daftuar)

- in OpenNetworkConnection we have a FindNode call, which gets a const
  char*, wheras we only have defined a FindNode for std::string

Add information about further notable changes:

- Big endian support
- Memory usage optimization
- Disable wallet transaction broadcast
- Stream isolation for Tor

ee9a2e4 Fix walletbackup.py after directory restructuring (Suhas Daftuar)

Remove possibility to send json encoded parameters to `/rest/getutxos/` to avoid possible DoS scenarios.

The JSON output option is untouched.
