Fix node ranges in the test framework.
don't override dir() in qa rpc tests

Replace "dir" with "dirname" in util.py in qa/rpc-tests/ because "dir"
is the name of a function in python.
Optimize -regtest setgenerate block generation

Speed up generating blocks in regression test mode, by moving
block-creating and nonce-finding directly into the setgenerate
RPC call (instead of starting up a mining thread and waiting for
it to find a block).

This makes the forknotify RPC test three times quicker, for
example (10 seconds runtime instead of 30 seconds, assuming
the initial blockchain cache is already built).
script: create sane error return codes for script validation and remove logging

Attempt to codify the possible error statuses associated with script
validation. script/types.h has been created with the expectation that it will
be part of the public lib interface. The other flag enums will be moved here in
a future commit.

Logging has also been removed in order to drop the dependency on core.h. It can
be re-added to bitcoind as-needed. This makes script verification finally free
of application state and boost!

7335ca1 [Qt] Fix height of BitcoinAmountField (Cozz Lovan)
[OSX, docs] update some release build informations

- switching release builds to 10.7
- release binary looks like 64bit only
- tested up to 10.10
- gitian builder builds against 10.7. The docs should be consistant.
- remove 32bit text because nowadays it's obvious to support 64bit only on OSX.
