3b570559f8 re-work -debug switch handling
- re-work -debug help message text
- make -debug log every debugging information again (even all categories)
- remove unneeded fDebug checks in front of LogPrint()/qDebug(), as that
  check is done in LogPrintf() when category is != NULL (true for all
  LogPrint() calls
- remove fDebug ONLY in code which is NOT performance-critical
- harmonize addrman category name
- deprecate -debugnet usage, should be used via -debug=net and remove the
  corresponding global

42656ea2e5 Make RPC password resistant to timing attacks
Fixes issue#2838; this is a tweaked version of pull#2845 that
should not leak the length of the password and is more generic,
in case we run into other situations where we need
timing-attack-resistant comparisons.

0e4b317555 Introduce a CChainParameters singleton class and regtest mode.
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.

f2763d6d60 fixed: include boost header as necessary
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.

1b43bf0d3a Rename util.h Sleep --> MilliSleep
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.

c8c2fbe07f Shutdown cleanup prep-work
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.

907a2aa4c7 Internal RNG for approximateBestSubset to prevent degenerate behavior.
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.

3fb9b99cca Allow lengthy block reconnections to be interrupted
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.

d07eaba195 Introduce -debugnet option, thereby quieting some redundant debug messages

	sending getdata: tx 8644cc97480ba1537214

	CTxMemPool::accept() : accepted 8644cc9748 (poolsz 6857)

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

	ERROR: FetchInputs() : 673dc195aa mempool Tx prev not found 1e439346fc
	stored orphan tx 673dc195aa (mapsz 19)

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

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.

ee12c3d60c Use filesystem::path instead of manual string tinkering
Where possible, use boost::filesystem::path instead of std::string or
char* for filenames. This avoids a lot of manual string tinkering, in
favor of path::operator/.

GetDataDir is also reworked significantly, it now only keeps two cached
directory names (the network-specific data dir, and the root data dir),
which are decided through a parameter instead of pre-initialized global
variables.

Finally, remove the "upgrade from 0.1.5" case where a debug.log in the
current directory has to be removed.

712fd182b7 Locking system overhaul, add condition variables
This commit simplifies the locking system: CCriticalSection becomes a
simple typedef for boost::interprocess::interprocess_recursive_mutex,
and CCriticalBlock and CTryCriticalBlock are replaced by a templated
CMutexLock, which wraps boost::interprocess::scoped_lock.

By making the lock type a template parameter, some critical sections
can now be changed to non-recursive locks, which support waiting via
condition variables. These are implemented in CWaitableCriticalSection
and WAITABLE_CRITICAL_BLOCK.

CWaitableCriticalSection is a wrapper for a different Boost mutex,
which supports waiting/notification via condition variables. This
should enable us to remove much of the used polling code. Important
is that this mutex is not recursive, so functions that perform the
locking must not call eachother.

Because boost::interprocess::scoped_lock does not support assigning
and copying, I had to revert to the older CRITICAL_BLOCK macros that
use a nested for loop instead of a simple if.

67a42f929b Network stack refactor
This introduces CNetAddr and CService, respectively wrapping an
(IPv6) IP address and an IP+port combination. This functionality used
to be part of CAddress, which also contains network flags and
connection attempt information. These extra fields are however not
always necessary.

These classes, along with logic for creating connections and doing
name lookups, are moved to netbase.{h,cpp}, which does not depend on
headers.h.

Furthermore, CNetAddr is mostly IPv6-ready, though IPv6
functionality is not yet enabled for the application itself.

1c4aab926e Retain only the most recent time samples
Remembering all time samples makes nTimeOffset slow to respond to
system clock corrections.  For instance, I start my node with a system
clock that's 30 minutes slow and run it for a few days.  During that
time, I accumulate 10,000 offset samples with a median of 1800
seconds.  Now I correct my system clock.  Without this change, my node
must collect another 10,000 samples before nTimeOffset is correct
again.  With this change, I must only accumulate 100 samples to
correct the offset.

Storing unlimited time samples also allows an attacker with many IP
addresses (ex, a large botnet) to perform a memory exhaustion attack
against Bitcoin nodes.  The attacker sends a version message from each
IP to his target, consuming more of the target's memory each time.
Time samples are small, so this attack might be impractical under the
old code, but it's impossible with the new code.

94f778bdeb Implement an mlock()'d string class for storing passphrases
SecureString is identical to std::string except with secure_allocator
substituting for std::allocator. This makes casting between them
impossible, so converting between the two at API boundaries requires
calling ::c_str() for now.

82dc6426b4 Move func 'REF' from util.h to serialize.h
util.h doesn't use REF, serialize.h does, creating a dependency of
serialize.h on util.h, but util.h already depends on serialize.h.  To
resolve this circular dependency the function 'REF' has now been moved
closer to one of its two points of use.

ecf1c79aad fix warnings: expression result unused [-Wunused-value]
In the assert()s take advantage of the fact that string constants
("string") are effectively of type 'const char []', which when used in
an expression yield a non-NULL pointer.

An assertion that should always fail can thus be formulated as:
  assert(!"fail);

An assertion where a text message should be added to the expression can
be written as such:
  assert("message" && expression);
