Code uses a windowing/precomputing strategy to minimize ECC math.
Every 8-bit window of the 256 bits that compose a possible scalar multiple has a complete map that's pre-computed.
The precomputed data is in secp256k1.go and the generator for that file is in gensecp256k1.go
Also fixed a spelling error in a benchmark test.
Results so far seem to indicate the time taken is about 35% of what it was before.
Closes#2
This change removes transactions from a newly connected block
from the orphan pool if they exist. Additionally, any orphan
transactions that are no longer orphan transactions are moved
to the mempool and inv'd to the currently connected peers.
This commit adds a couple of options which were not details in the sample
config file. It also fixes a couple of typos and makes the example default
maxpeers setting in the config file match the actual default used in btcd.
The go vet command complains about untagged struct initializers when
defining a ShaHash directly. This seems to be a limitation where go vet
does not exclude the warning for types which are a constant size byte
array like it does for normal constant size byte array definition.
This commit simply modifies the code to use a constant definition cast to
a ShaHash to overcome the limitation of go vet.
Add the word 'string' to the error string so if this is printed, it
will be clearer that it was a hash string decode that failed (as
opposed to other errors creating a ShaHash from a byte slice) and
change 'chars' to 'bytes', since the string length is measured in
bytes, not UTF-8 code points.

This commit explicitly ignores errors that were already intentionally
ignored in btcctl by using an _ to make the errcheck utility happy. It is
also nice to make it explicit that the error is being ignored
intentionally rather than leave questions of whether it was accidentally
forgotten.
