TEST:
blockchain_export -h
This should show "berkeley" as an available option to --database.
With an existing BerkeleyDB database, run:
blockchain_export --database berkeley
This is already the default for the daemon, but by checking a command
line argument and calling a Blockchain member function setter.
Initialize the variable to false so it's not dependent on an external
command-line argument check. This allows utilities like
blockchain_import to have a reasonable default without code changes.

When keys are contiguous and monotonically increasing, this gets
denser page utilization (doesn't leave padding in page splits).
Can't be used for keys that are inserted in random order (e.g. hashes)
In total this only saves around 1.5% of space compared to original
DB code. The previous patch accounted for 0.8% savings on its own;
the blocks tables just aren't that big.
These modes match those optionally provided as part of the daemon's
--db-type argument.
Argument after the # is interpreted as a composite mode if there's only
one (no comma separated arguments).
Sample usage:
blockchain_import --database lmdb#fastest
blockchain_import --database berkeley#fastest
Multiple specific DB flags are still supported, e.g.
blockchain_import --database lmdb#nosync,nordahead
blockchain_import --database berkeley#txn_nosync

Add another DB error exception type to distinguish failed txn setup from
general use of txn.
This keeps the error handling flow the same as before the block-level
txn setup changes that moved control up a layer to BlockchainDB.
Remove LINK_SEARCH_START_STATIC and LINK_SEARCH_END_STATIC. This is more
appropriate when the compiler flag -static is used.
This had been causing CMake to omit the linker flags necesssary to
distinguish static and dynamic library linking. CMake had assumed static
linking for the target, causing it to omit explicit static link flags.
That is problematic without the -static compile flag being set.
With a library located in system directories, like libboost_date_time,
the full static path (.a), though found correctly by CMake, was treated
by the linker as a dynamic library. This is because
target_link_libraries() transforms the full path to -l<libname> if it's
in a system directory. Without -static or explicit linker flags, the
dynamic library (.so) is linked.
Removing the above two properties removes the assumption of static. So
-Wl;-Bstatic is inserted where needed. This causes -l<libname> to
properly refer to the static library instead of dynamic.
Setting to no or 0 also works. If set, any other value enables it.
Useful for running with valgrind in cases where it fails at
properly implementing AES-NI.
We also replace the --fakechain option with an optional structure
containing details about configuration for the core/blockchain,
for test purposes. This seems more future friendly.

If it is, it points to reuse of a tx key, which isn't meant to happen.
If it does, a key image collision means that only one of those
outputs is spendable, so the wallet selects the larger amount,
unless that output was spent already.
This causes a discrepancy betewen reported received inputs and
payment total.
Since tx keys are 256 bits, this should never happen except if
done on purpose, or if a sender uses a bad PRNG.
Locking just one db turns out to not have been a good idea, since
the pool and p2p state fdles have to be used anyway.
Also ensure the directory exists before tring to lock.
