all: update github.com/spf13/cobra to v1.1.3 (#2572 )

This removes indirect dependencies from go.mod, and
includes the fix for the missing -help flag info.

The latest cobra release is v1.2.1. Given that there were
minor security-related dependency cleanup during v1.2 release,
I was tempted to pick up the latest version, but that caused
dependency updates in golang.org/x/sys and golang.org/x/tools
which may be too recent (golang.org/x/* follow the go's release
support policy, so recent versions may not be compatible with
go versions beyond go's official version support policy).

Verified that dlv still builds with go1.12.x.
(go1.12 is the oldest version of go that can build the latest delve already).

$ go get -d github.com/spf13/cobra@v1.1.3
$ go mod tidy
$ go mod vendor
$ go run _scripts/gen-usage-docs.go

dlv log

Help about logging flags.

Synopsis

Logging can be enabled by specifying the --log flag and using the --log-output flag to select which components should produce logs.

The argument of --log-output must be a comma separated list of component names selected from this list:

debugger	Log debugger commands
gdbwire		Log connection to gdbserial backend
lldbout		Copy output from debugserver/lldb to standard output
debuglineerr	Log recoverable errors reading .debug_line
rpc		Log all RPC messages
dap		Log all DAP messages
fncall		Log function call protocol
minidump	Log minidump loading

Additionally --log-dest can be used to specify where the logs should be written. If the argument is a number it will be interpreted as a file descriptor, otherwise as a file path. This option will also redirect the "server listening at" message in headless and dap modes.

Options

  -h, --help   help for log
