Mark LevelDB "Read" and "Exists" functions as const.

Mark the "Read" and "Exists" functions in CLevelDBWrapper as "const".
They do not change anything in the DB, by definition.
Make appropriate getter-routines "const" in CCoinsView.

Mark the "Get"/"Have" routines in CCoinsView and subclasses as "const".
Use const CCoinsView's at some places.

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

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.
Remove unused `alignup` function from util.h
Remove unused function `ByteReverse` from util.h
Move SetThreadPriority implementation to util.cpp instead of the header

Put the THREAD_* and PRIO_ constants in compat.h.
move functions in main and net to implementation files
Move functions in wallet.h to implementation file

Breaks compile-time dependency of wallet.h on util.
Move `S_I*` constants and `MSG_NOSIGNAL` to compat.h
Move `*Version()` functions to version.h/cpp
Move `COIN` and `CENT` to core.h

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