all: add Unwrap and Is methods to various error types
Add Unwrap methods to types which wrap an underlying error:
"encodinc/csv".ParseError
"encoding/json".MarshalerError
"net/http".transportReadFromServerError
"net".OpError
"net".DNSConfigError
"net/url".Error
"os/exec".Error
"signal/internal/pty".PtyError
"text/template".ExecError
Add os.ErrTemporary. A case could be made for putting this error
value in package net, since no exported error types in package os
include a Temporary method. However, syscall errors returned from
the os package do include this method.
Add Is methods to error types with a Timeout or Temporary method,
making errors.Is(err, os.Err{Timeout,Temporary}) equivalent to
testing the corresponding method:
"context".DeadlineExceeded
"internal/poll".TimeoutError
"net".adrinfoErrno
"net".OpError
"net".DNSError
"net/http".httpError
"net/http".tlsHandshakeTimeoutError
"net/pipe".timeoutError
"net/url".Error
