cd9696fc97 Encapsulate BDB environment inside new CDBEnv class 
Cleans up and organizes several scattered functions and variables related to
the BDB env.  Class CDBInit() existed to provide a
guaranteed-via-C++-destructor cleanup of the db environment.

A formal CDBEnv class provides all of this inside a single wrapper.

b52a270538 Reorganize(): remove spurious TxnAbort() 
If Reorganize() fails, then its caller, CBlock::SetBestChain(),
will call TxnAbort().

Redundant TxnAbort() calls are harmless.  The second will return an
error return value, with no other side effects.  TxnAbort() return
values are generally never checked.  The impact is nil.

394b9298fa Default to DB_TXN_WRITE_NOSYNC for all transactional operations 
* This is safer than DB_TXN_NOSYNC, and does not appear to impact
  performance.
* Applying this to the dbenv is necessary to avoid many fdatasync(2)
  calls on db 5.x
* We carefully and thoroughly flush databases upon shutdown and
  other important events already.

9af080c351 Reopen debug.log on SIGHUP 
The best log rotation method formerly available was to configure
logrotate with the copytruncate option.  As described in the logrotate
documentation, "there is a very small time slice between copying the
file and truncating it, so some logging data might be lost".

By sending SIGHUP to the server process, one can now reopen the debug
log file without losing any data.

fea25712ca Serialize access to debug.log stream 
Acquire an exclusive, advisory lock before sending output to debug.log
and release it when we're done. This should avoid output from multiple
threads being interspersed in the log file.

We can't use CRITICAL_SECTION machinery for this because the debug log
is written during startup and shutdown when that machinery is not
available.

(Thanks to Gavin for pointing out the CRITICAL_SECTION problems based
on his earlier work in this area)

62922c8ab0 Cache signature verifications 
Create a maximum-10MB signature verification result cache.
This should almost double the number of transactions that
can be processed on a given CPU, because before this change
ECDSA signatures were verified when transactions were added
to the memory pool and then again when they appeared in
a block.

4add41a2a6 Further DoS prevention: Verify signatures last 
Loop over all inputs doing inexpensive validity checks first,
and then loop over them a second time doing expensive signature
checks. This helps prevent possible CPU exhaustion attacks
where an attacker tries to make a victim waste time checking
signatures for invalid transactions.

3a25a2b9b0 Update License in File Headers 
I originally created a pull to replace the "COPYING" in crypter.cpp and
crypter.h, but it turned out that COPYING was actually the correct
file.

Also, trim a few trailing whitespace in main.cpp.
