4579cfb71b Refactor several network-specific params to btcnet.
This commit refactors the code to make use of the btcnet package for
network-specific parameters instead of switching on the specific network.

For example, the percentage of the network that needs to run version 2
blocks is different between testnet and mainnet.  Previously the code was
using a switch to choose these values.  With this refactor, those
parameters are part of the network parameters provided when creating a new
chain instance.

Another example is checkpoints, which have been moved to btcnet so they
can be specified by the caller instead of hard coded into this package.
As a result, the checkpoints for the standard networks are now specified
in the btcnet package.

This makes it easier to add new networks such as a testnet4 should it
become needed.  It also allows callers to define their own custom network
parameters without having to modify the code of the package to add new
switch cases for the custom network.

fb8ab4200f Add more chain-related fields and checkpoints.
This commit adds more chain-related fields to the parameters as a part of
converting btcchain to work with btcnet parameters instead of coding the
network-specific knowledge into the package itself.

It also moves the checkpoints from btcchain since checkpoints are a
network parameter and make more sense here.

6d8b873923 Raise maxStandardSigScriptSize to 1650.
This commit raises the maximum allowed size for a standard signature
script to cover a 15-of-15 multi-signature pay-to-script-hash with
compressed pubkeys.

This mirrors a recent change to remain compatible with Bitcoin Core.

ok @owinga who also helped verify and correct the script math.

Closes #128.

bcc78565fd Initial pass at updating to btcnet.
This change modifies the params struct to embed a *btcnet.Params,
removing the old parameter fields that are handled by the btcnet
package.

Hardcoded network checks have also been removed in favor of modifying
behavior based on the current active net's parameters.

Not all library packages, notable btcutil and btcchain, have been
updated to use btcnet yet, but with this change, each package can be
updated one at a time since the active net's btcnet.Params are
available at each callsite.

536c1e3c29 Add parameters used by btcd.
This change adds two parameters to the Params struct which are used by
btcd to alter behavior based on the active network, rather than
hardcoding checks for a particular network.

The first, ResetMinDifficulty, specifies whether the target difficulty
can change between the retarget intervals.

The second, RelayNonStdTxs, specifies whether standard transaction
checks should not be performed when accepting mempool transactions.

The zero values (false) for both of these bools are the correct
parameter values for mainnet.

While here, rename the test network version 3 to "testnet3", as both
btcd and btcwallet will include additional handling to rename this to
"testnet" for directory names, and a switch to "testnet3" is planned
in the future.

77c02f36ee Cleanup new code introduced by Pull Request #4.
- Keep comments to 80 cols for consistency with the rest of the code base
- Made verify a method off of Signature instead of PublicKey since one
  verifies a signature with a public key as opposed to the other way
  around
- Return new signature from Sign function directly rather than creating a
  local temporary variable
- Modify a couple of comments as recommended by @owainga
- Update sample usage in doc.go for both signing messages and verifying
  signatures

1dbf389ceb Optimize public key serialization.
This change removes the internal pad function in favor a more opimized
paddedAppend function.  Unlike pad, which would always alloate a new
slice of the desired size and copy the bytes into it, paddedAppend
only appends the leading padding when necesary, and uses the builtin
append to copy the remaining source bytes.  pad was also used in
combination with another call to the builtin copy func to copy into a
zeroed byte slice.  As the slice is now created using make with an
initial length of zero, this copy can also be removed.

As confirmed by poking the bytes with the unsafe package, gc does not
zero array elements between the len and cap when allocating slices
with make().  In combination with the paddedAppend func, this results
in only a single copy of each byte, with no unnecssary zeroing, when
creating the serialized pubkeys.  This has not been tested with other
Go compilers (namely, gccgo and llgo), but the new behavior is still
functionally correct regardless of compiler optimizations.

The TestPad function has been removed as the pad func it tested has
likewise been removed.

6a325f4c6a Improve getwork interaction with regtest mode.
Ordinarily, getwork will return an error if btcd is not connected to any
other peers.  This commit relaxes that requirement when running in
regression test mode since it is useful for development purposes.

While here, also improve check which returns an error from getwork is not
current to exclude the check when the best chain height is zero since the
code never believes it is current when at height 0.

c2a1444a88 Add new reject command.
This commit adds the new reject protocol message added to recent versions
of the reference implementation.  This message is intended to be used in
response to messages from a remote peer when it is rejected for some
reason such as blocks being rejected due to not conforming to the chain
rules, transactions double spending inputs, and version messages sent
after they're already sent.

This is work toward issue #9.

- Group the new read/writeVarBytes functions together to be consistent
  with the existing code
- Modify the comments on the new read/writeVarBytes to be a little more
  descriptive and consistent with existing code
- Use "test payload" for field name in the tests for the
  read/writeVarBytes functions which is more accurate
- Remove reserved param from NewAlert since there is no point is having
  the caller deal with a reserved param
- Various comment tweaks for clarity and consistency
- Use camel case for fuction params for consistency
- Move the NewAlert and NewAlertFromPayload functions after the receiver
  definitions for code layout consistency

47e65634a7 Use btcd pver instead of wire pver in RPC encoding.
Along the same lines as the previous commit, the RPCs that return

are both the same value, so there is no issue.  However, they will not
always be the same.
