d71794de19 Make ApplyWithError a public method on errorableFlag
Add to altsrc flags. Otherwise, flagSet() was bypassing altsrc's attempt
at shadowing.

e367fafa3d Return an error when parsing environment variables for values fails
Currently cli silently (aside from IntSlice and Int64Slice which oddly
printed directly to the error stream) ignores failures that occur when
parsing environment variables for their value for flags that define
environment variables. Instead, we should propogate up the error to the
user.

This is accomplished in a backwards compatible manner by adding a new,
internal, interface which defines an applyWithError function that all
flags here define. In v2, when we can modify the interface, we can drop
this secondary interface and modify `Apply` to return an error.

a00c3f5872 Consider empty environment variables as set
When assigning values to flags (also when interogatting via
`context.(Global)IsSet`.

For boolean flags, consider empty as `false`.

Using `syscall.Getenv` rather than `os.LookupEnv` in order to support
older Golang versions.

Allow for pluggable flag-level help text formatting
by defining `cli.DefaultFlagStringFunc` with a default value that uses
`withEnvHint`, conditionally running a given flag's `FormatValueHelp` if
present.

New `Hide` variable for all Flags
This is a way to provide hidden flags for app, command and subcommands

For example:

  --generate-bash-completion global flag shouldn't be printed along
  with other flags as it might generally confuse people into thinking
  that 'generate' in-fact would generate a bash completion file for them
  to be used along with their app.

Also in general one would want to hide some flags for their apps.
