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.

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.

Kills the "make" line as well.

Removes the unnecessary directions that encourage people to force install openssl into /usr/local with Homebrew. Unnecessary, and potentially quite risky. @theuni okayed this removal [here](https://github.com/bitcoin/bitcoin/pull/4740#issuecomment-53076840).

Upon failure, BOOST_CHECK_EQUAL provides additional diagnostic information,

The homebrew instructions were outdated - berkeley-db4 hasn't worked for months, based on the questions I'm seeing on Google/SO.  So I added a section explaining how to install berkeley-db4 using homebrew and move on with your life.  Thanks for the rest of the documentation!

All unused.

Removed in

This avoids a dependency on util.h if just tinyformat is needed.
