a1bd15e7c2 Fix --onion.
The configured onion proxy was not being used due to checking if the
passed string had suffix '.onion', which never matched because the
port number is part of the string.

3aac3bda44 Update README.md install section.
This commit adds an additional step to the README.md install section to
run the go version command and check the version so people that are
installing it for the first time and ensure they are running a high
enough version and have GOROOT and GOPATH set correctly.

007bee5ec8 Add new option --torisolation
Tor stream isolation randomizes proxy user credentials resulting in
Tor creating a new circuit for each connection.  This makes it more

19eae8d8a1 blockchain: Split block and header validation.
This commit refactors the consensus rule checks for block headers and
blocks in the blockchain package into separate functions.  These changes
contain no modifications to consensus rules and the code still passes all
block consensus tests.  It is only a refactoring.

This is being done to help pave the way toward supporting concurrent
downloads.  While the package already supports headers-first mode up
through the latest checkpoint through the use of the BFFastAdd flag and
hard-coded checkpoints, it currently only works when downloading from a
single peer.  In order to support concurrent downloads from multiple
peers, the ability for the caller to do things such as independently
checking a block header (both context-free and full-context checks) will
be needed.

There are several more changes that will be necessary to support
concurrent downloads as well, such as making the package concurrent safe,
modifying it to make use of the new database API, etc.  Those changes are
planned for future commits.

788c316879 Fix listtransactions/gettransaction result structs.
The following changes were made to ListTransactionsResult (which
models the long result format used by listtransactions,
listsinceblock, etc.):

  - Fee made optional (float64 -> *float64 + omitempty)
  - BlockIndex made optional (int64 + omitempty -> *int64 + omitempty)
  - InvolvesWatchOnly added (bool + omitempty)
  - Vout added (uint32)

The following changes were made to GetTransactionDetailsResult (which
models the short result format of listtransactions):

  - InvolvesWatchOnly added (bool + omitempty)
  - Fee added (*float64 + omitempty)
  - Vout added (uint32)

The combination of pointer types and the omitempty struct tag allow
excluding the field from the JSON object, or including it with the
zero value.  This is useful in particular for the fee fields, which
should be included whenever the category is "send" even if the fee is
zero.  Other optional fields which are only added to the result object
with non-zero values (such as includeswatchonly) can be reduced to
simply an omitempty tag without the pointer type.

edc0d15882 txscript: Consensus audit.
This commit contains fixes from the results of a thorough audit of
txscript to find any cases of script evaluation which doesn't match the
required consensus behavior.  These conditions are fairly obscure and
highly unlikely to happen in any real scripts, but they could have
nevertheless been used by a clever attacker with malicious intent to
cause a fork.

Test cases which exercise these conditions have been added to the
reference tests and will contributed upstream to improve the quality for
the entire ecosystem.

f284b9b394 txscript: Match Bitcoin Core OP_IFDUP behavior.
Unlike OP_IF and OP_NOTIF which interpret the top stack item as a
number, OP_IFDUP interprets it as a boolean.  This has important
consequences because numbers are imited to int32s while booleans can be
an arbitrary number of bytes.

The offending script was found and reported by Jonas Nick through the
use of fuzzing.

927a0e9c37 txscript: Test consistency and cleanup.
- Move reference tests to test package since they are intended to
  exercise the engine as callers would
- Improve the short form script parsing to allow additional opcodes:
  DATA_#, OP_#, FALSE, TRUE
- Make use of a function to decode hex strings rather than manually
  defining byte slices
- Update the tests to make use of the short form script parsing logic
  rather than manually defining byte slices
- Consistently replace all []byte{} and [][]byte{} with nil
- Define tests only used in a specific function inside that func
- Move invalid flag combination test to engine_test since that is what
  it is testing
- Remove all redundant script tests in favor of the JSON-based tests in
  the data directory.
- Move several functions from internal_test.go to the test files
  associated with what the tests are checking

005b540895 txscript: Separate code for standard scripts.
This commit moves all code related to standard scripts into a separate
file named standard.go as well as the associated tests into
standard_test.go.  Since the code in address.go and address_test.go is
only related to standard scripts, it has been combined into the new
files and the old files deleted.

The intent here is to make it clear that the code in standard.go is not
related to consensus.

b6e52fbd93 txscript: Convert to new scriptnum type.
This commit implements a new type, named scriptNum, for handling all
numeric values used in scripts and converts the code over to make use of
it.  This is being done for a few of reasons.

First, the consensus rules for handling numeric values in the scripts
require special handling with subtle semantics.  By encapsulating those
details into a type specifically dedicated to that purpose, it
simplifies the code and generally helps prevent improper usage.

Second, the new type is quite a bit more efficient than big.Ints which
are designed to be arbitrarily large and thus involve a lot of heap
allocations and additional multi-precision bookkeeping.  Because this
new type is based on an int64, it allows the numbers to be stack
allocated thereby eliminating a lot of GC and also eliminates the extra
multi-precision arithmetic bookkeeping.

The use of an int64 is possible because the consensus rules dictate that
when data is interpreted as a number, it is limited to an int32 even
though results outside of this range are allowed so long as they are not
interpreted as integers again themselves.   Thus, the maximum possible
result comes from multiplying a max int32 by itself which safely fits
into an int64 and can then still appropriately provide the serialization
of the larger number as required by consensus.

Finally, it more closely resembles the implementation used by Bitcoin
Core and thus makes is easier to compare the behavior between the two
implementations.

This commit also includes a full suite of tests with 100% coverage of
the semantics of the new type.

a8fe1ad5fe txscript: Code consistency and doco improvements.
This commit contains a lot of cleanup on the txscript code to make it
more consistent with the code throughout the rest of the project.  It
doesn't change any operational logic.

The following is an overview of the changes:

- Add a significant number of comments throughout in order to better
  explain what the code is doing
- Fix several comment typos
- Move a couple of constants only used by the engine to engine.go
- Move a variable only used by the engine to engine.go
- Fix a couple of format specifiers in the test prints
- Reorder functions so they're defined before/closer to use
- Make the code lint clean with the exception of the opcode definitions

2e433b0eb3 txscript: Move opcode execution logic to engine
This commit moves the opcode execution logic from the opcode type to the
engine type because execution of an opcode modifies the engine state
(primarily the main and alternate data stacks) as opposed to the state
of the opcode.  Making the engine the receiver more clearly indicates
this fact.

the {G,S}etStack and {G,S}etAltStack functions which return the items as
a slice of byte slices ([][]byte) for caller access while stepping.

ab2ed710cb Fix 'add/delnode' type switch evaluation in server
* The cases for the 'addnode' command were previously
  stacked on top the new cases for the 'node' command.
  The intended behavior was to create a fall through and
  handle both commands. However, trying to use this
  syntax with a type switch caused the first case to be
  ignored.
* addnode' specific functions and structs in the server
  have been removed. Instead, the 'add' and 'del' subcommands
  are now proxied to the matching 'node' cmd functions.
