665bdd3b Fix off-by-one errors in use of IsFinalTx() (Peter Todd)

Update English .ts file from source as well as pull changes from transifex
to current translation.

f3005c82 [Qt] harmonize strings used when exporting in addressbookpage (Philip Kaufmann)

Previously CreateNewBlock() didn't take into account the fact that
IsFinalTx() without any arguments tests if the transaction is considered
final in the *current* block, when both those functions really needed to
know if the transaction would be final in the *next* block.

Additionally the UI had a similar misunderstanding.

Also adds some basic tests to check that CreateNewBlock() is in fact
mining nLockTime-using transactions correctly.

Thanks to Wladimir J. van der Laan for rebase.

Unit test fixes for AssertLockHeld / -DDEBUG_LOCKORDER

Unit tests would fail if compiled with -DDEBUG_LOCKORDER (AssertLockHeld()
would fail; AssertLockHeld() relies on the DEBUG_LOCKORDER code to keep
track of locks held).

Fixed by LOCK'ing the wallet mutex in the unit tests that manipulate the
wallet.

After the tinyformat switch sprintf() family functions support passing
actual std::string objects.

Remove unnecessary c_str calls (236 of them) in logging and formatting.

Switch to tinyformat-based formatting.

Tinyformat is a typesafe drop-in replacement for C99 printf functions:

4e57e238 enable full GCC Stack-smashing protection for all OSes (Philip Kaufmann)

This avoids a dependency on libssp-0.dll when built with
-fstack-protector-all.

- rebuilt some ui file layout to remove unreal values from the files
- remove an unneeded attribute from an ui file
- add / remove some spaces in files

- change our hardening options to use -fstack-protector-all even for
  Windows builds, as we recently switched to a newer compiler suite
- also removes an obsolete workaround for GCC 4.5
  (https://bugs.launchpad.net/ubuntu/+source/gcc-4.5/+bug/691722), which
  required to first set -fno-stack-protector, before -fstack-protector-all
