Document that CPubKey.IsValid() is consensus critical
Require OSX 10.6, 64-bit

Drop support for 32-bit or pre-10.6 Macs.

Also, some of the OSX build docs hadn't been updated since the
autotools change.
Remove CWalletTx::vfSpent

Use the spent outpoint multimap to figure out which wallet transaction
outputs are unspent, instead of a vfSpent array that is saved
to disk.

Re-enable UPnP by default in gitian builds

IIRC this was the case with 0.8.6, so let's keep this to avoid the risk
of losing connectable nodes with 0.9 release.

Also our miniupnpc library was recently updated and I've heard
reports that it works better than before now.
Make tinyformat errors raise an exception instead of assert()ing

By default tinyformat errors such as 'wrong number of conversion
specifiers in format string' cause an assertion failure.

Raise an exception instead so that error handling can recover or can
show an appropriate error.

qt: Modernize 'confirmed' terminology in shown tx status

These days we regard transactions with one confirmation to be
'Confirmed'.
Waiting for 6 confirmations is a recommendation but should not
keep the transaction shown as unconfirmed.

Misc code sanity:

- Merge maturity/status enums, they had become completely disjunct
- 'confirmed' flag is now called 'countsForBalance' for clarity
