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.

7a15109c04 Remove invalid dependent orphans from memory 
Remove orphan transactions from memory once
all of their parent transactions are received
and they're still not valid.
Thanks to Sergio Demian Lerner for suggesting this fix.

83743ed681 Make lsn_reset ("detach databases") optional and off by default. 
Add an option -detachdb (and entry in OptionDialog), without which no
lsn_reset is called on addr.dat and blkindex.dat. That means these
files cannot be moved to a new environment, but shutdown can be
significantly faster. The wallet file is always lsn_reset'ed.

-detachdb corresponds to the old behaviour, though it is off by
default now to speed up shutdowns.

5aa0b23825 CBlock::WriteToDisk() properly checks ftell(3) for error return 
Rather than storing ftell(3)'s return value -- a long -- in an
unsigned int, we store and check a properly typed temp.  Then, assured a
non-negative value, we store in nBlockPosRet.

faf705a42a Prefer 'unsigned int' for loop index variables tested against ::size() 
C++ STL ::size() generally returns unsigned, which implies that "int idx"
style of loop variable will generate a signed-vs-unsigned comparison warning
when testing the loop exit condition "idx < blah.size()"

Update areas of the bitcoin code where loop variables may be more properly and
correctly defined as unsigned.
