aa41ac21 Test IsPushOnly() with invalid push (Peter Todd)

d0867acb Use const CCoinsView's at some places. (Daniel Kraft)
a3dc587a Make appropriate getter-routines "const" in CCoinsView. (Daniel Kraft)
ffb4c210 Mark LevelDB "Read" and "Exists" functions as const. (Daniel Kraft)

Split up util.cpp/h into:

- string utilities (hex, base32, base64): no internal dependencies, no dependency on boost (apart from foreach)
- money utilities (parsesmoney, formatmoney)
- time utilities (gettime*, sleep, format date):
- and the rest (logging, argument parsing, config file parsing)

The latter is basically the environment and OS handling,
and is stripped of all utility functions, so we may want to
rename it to something else than util.cpp/h for clarity (Matt suggested
osinterface).

Breaks dependency of sha256.cpp on all the things pulled in by util.

Eventually these should end up in `money.h` after monetary
amounts are typedef'ed, but at least they don't belong in `util.h`.

Breaks compile-time dependency of wallet.h on util.

Put the THREAD_* and PRIO_ constants in compat.h.

Now that we no longer use the median filter to keep track of
the number of blocks of peers, that's the only place it is used.

At some places where it is possible (e. g., CheckInputs), use a const
version of CCoinsView instead of a non-const one.

Mark the "Get"/"Have" routines in CCoinsView and subclasses as "const".

Mark the "Read" and "Exists" functions in CLevelDBWrapper as "const".
They do not change anything in the DB, by definition.

Break into two steps:
* Generate hash list
* Build data file(s) from local bitcoind blocks/ directory.

This supports building one large bootstrap.dat, or multiple
smaller blocks/blkNNNNN.dat files.
