The new class is accessed via the Params() method and holds
most things that vary between main, test and regtest networks.
The regtest mode has two purposes, one is to run the
bitcoind/bitcoinj comparison tool which compares two separate
implementations of the Bitcoin protocol looking for divergence.
The other is that when run, you get a local node which can mine
a single block instantly, which is highly convenient for testing
apps during development as there's no need to wait 10 minutes for
a block on the testnet.
Without this include, sometimes BOOST_VERSION was defined and sometimes
it was not, depending on which includes came before it. The result was a
random mix of sleep or sleep_for for boost versions >= 1.50.
- removes our NewThread() function an replaces remaining calls with
boost::thread with our TraceThread template
- remove ExitThread() function
- fix THREAD_PRIORITY_ABOVE_NORMAL for non Windows OSes
- explicitly set the default of all GetBoolArg() calls
- rework getarg_test.cpp and util_tests.cpp to cover this change
- some indentation fixes
- move macdockiconhandler.h include in bitcoin.cpp to the "our headers"
section
Two reasons for this change:
1. Need to always use boost::thread's sleep, even on Windows, so the
sleeps can be interrupted (prior code used Windows' built-in Sleep).
2. I always forgot what units the old Sleep took.
Create a boost::thread_group object at the qt/bitcoind main-loop level
that will hold pointers to all the main-loop threads.
This will replace the vnThreadsRunning[] array.
For testing, ported the BitcoinMiner threads to use its
own boost::thread_group.
This fixes test_bitcoin failures on openbsd reported by dhill on IRC.
On some systems rand() is a simple LCG over 2^31 and so it produces
an even-odd sequence. ApproximateBestSubset was only using the least
significant bit and so every run of the iterative solver would be the
same for some inputs, resulting in some pretty dumb decisions.
Using something other than the least significant bit would paper over
the issue but who knows what other way a system's rand() might get us
here. Instead we use an internal RNG with a period of something like
2^60 which is well behaved. This also makes it possible to make the
selection deterministic for the tests, if we wanted to implement that.
Initialize the OutputDebugStringF mutex and file pointer using
boost::call_once, to be thread-safe.
Make the return value of OutputDebugStringF really be the number of
characters written (*printf() semantics).
Declare the fReopenDebugLog flag volatile, since it is changed from
a signal handler.
And don't declare OutputDebugStringF() as inline.
When the coin database is out of date with the block database, the
best block in it is automatically switched to. This reconnection
process can take time, so allow it to be interrupted.
This also stops block connection as soon as shutdown is requested,
leading to a faster shutdown.
Introduce a AllocateFileRange() function in util, which wipes or
at least allocates a given range of a file. It can be overriden
by more efficient OS-dependent versions if necessary.
Block and undo files are now allocated in chunks of 16 and 1 MiB,
respectively.
NOTE: These thread names are visible in gdb when using 'info threads'.
Additionally both 'top' and 'ps' show these names *unless* told to
display the command-line instead of task name.

Prior to this change, each TX typically generated 3+ debug messages,
askfor tx 8644cc97480ba1537214 0
sending getdata: tx 8644cc97480ba1537214

After this change, there is only one message for each valid TX received
CTxMemPool::accept() : accepted 22a73c5d8c (poolsz 42)
and two messages for each orphan tx received

The -debugnet option, or its superset -debug, will restore the full debug
output.
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.
