Ignore required flags when DisableFlagParsing (#1095)
When a command request to DisableFlagParsing, it should not fail due
to a missing required flag.  In fact, such a check will always fail
since flags weren't parsed!

Rename BashCompDirectives to ShellCompDirectives (#1082)
Since the completion directives will be used for all shells, and that
these names will be consumed by users, this is a more appropriate name.

Add support for custom completions in Go (#1035)
This commit allows programs using Cobra to code their custom completions
in Go instead of Bash.

The new ValidArgsFunction field is added for commands, similarly to
ValidArgs.  For flags, the new function
Command.RegisterFlagCompletionFunc() is added.

When either of the above functions is used, the bash completion script
will call the new hidden command '__complete', passing it all
command-line arguments. The '__complete' command will call
the function specified by Command.ValidArgsFunction or by
Command.RegisterFlagCompletionFunc to obtain completions from the
program itself.

Partial Revert of #922 (#1068)
Issue Reference: https://github.com/spf13/cobra/issues/1056

https://github.com/spf13/cobra/pull/922 introduced a new error
type that emitted when a command was not runnable. This caused
all commands w/o a run function set to error w/ that message and a status code of 1.

This change reverts the addition of that new error. Similar
functionality can be accomplished by leveraging RunE.

eb58983359 Add CalledAs method to cobra.Command (w/ tests) (#567)
* Add `CalledAs` method to Command (w/ tests)

The `CalledAs` method returns the name of the command or alias that
invoked the command -- as long as the command was actually invoked.
Otherwise, it returns the empty string.

The opens up possibilies for commands to behave differently based on
which alias invoked the command (in the same vein as Linux programs
which adjust their behavior based on the value of argv[0]).

* Fixed formatting
