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

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

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.
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.
