This commit converts the dependency management from Godeps to the vendor folder, also switching the tool from godep to trash. Since the upstream tool lacks a few features proposed via a few PRs, until those PRs are merged in (if), use github.com/karalabe/trash. You can update dependencies via trash --update. All dependencies have been updated to their latest version. Parts of the build system are reworked to drop old notions of Godeps and invocation of the go vet command so that it doesn't run against the vendor folder, as that will just blow up during vetting. The conversion drops OpenCL (and hence GPU mining support) from ethash and our codebase. The short reasoning is that there's noone to maintain and having opencl libs in our deps messes up builds as go install ./... tries to build them, failing with unsatisfied link errors for the C OpenCL deps. golang.org/x/net/context is not vendored in. We expect it to be fetched by the user (i.e. using go get). To keep ci.go builds reproducible the package is "vendored" in build/_vendor.

#### type Token
|
|
|
|
```go
|
|
type Token int
|
|
```
|
|
|
|
Token is the set of lexical tokens in JavaScript (ECMA5).
|
|
|
|
#### func IsKeyword
|
|
|
|
```go
|
|
func IsKeyword(literal string) (Token, bool)
|
|
```
|
|
IsKeyword returns the keyword token if literal is a keyword, a KEYWORD token if
|
|
the literal is a future keyword (const, let, class, super, ...), or 0 if the
|
|
literal is not a keyword.
|
|
|
|
If the literal is a keyword, IsKeyword returns a second value indicating if the
|
|
literal is considered a future keyword in strict-mode only.

|
|
#### func (Token) String
|
|
|
|
```go
|
|
func (tkn Token) String() string
|
|
```
|
|
String returns the string corresponding to the token. For operators, delimiters,
|
|
and keywords the string is the actual token string (e.g., for the token PLUS,
|
|
the String() is "+"). For all other tokens the string corresponds to the token
|
|
name (e.g. for the token IDENTIFIER, the string is "IDENTIFIER").
