fde174645a Shell: Accept empty set of completions from program completer 
Falling back to default completions goes directly against the users'
wishes :P

ad4470bc39 Shell: Escape program-provided completions unless they're marked as code 
This makes it so program-provided completions don't have to worry about
escaping, making the Shell the only authority on escaping.

calls with TRYs. :^)

cc157629b4 Shell: Expand glob to only directories if it ends with a slash 
The glob "*/" should only expand to directories, and the directories
should also have a trailing slash. This commit also replaces
Shell::split_path with StringView::split_view since it accomplishes the
same task.

This is also available in the regular shell mode, as it's a generally
useful builtin to have.

aeee98b3a1 AK+Everywhere: Remove the null state of DeprecatedString 
This commit removes DeprecatedString's "null" state, and replaces all
its users with one of the following:
- A normal, empty DeprecatedString
- Optional<DeprecatedString>

Note that null states of DeprecatedFlyString/StringView/etc are *not*
affected by this commit. However, DeprecatedString::empty() is now
considered equal to a null StringView.

84777fbe62 Shell: Allow the user to set the prompt using PROMPT() 
This allows the prompt to be dynamically configurable, making it
possible to display various bits of information in the prompt.

fb60db7b00 Shell: Add builtin command to reset the internal state 
The new builtin command "reset" now resets the entire internal state by
virtually destructing the Shell state and re-constructing it.

This helps for example when setting a new hostname and wanting to view
it in the current Shell program.

3f35ffb648 Userland: Prefer _string over _short_string 
As `_string` can't fail anymore (since 3434412), there are no real
benefits to use the short variant in most cases.

0c86ee3876 Shell: Rewrite Shell::possibly_print_error without deprecated API 
Also, not allocating copies of the current string all the time should be
a tiny bit more efficient. We can do this because the 'current_line' is
only used while reporting the error, so it will not be used once we
begin reading the next line.

359d6e7b0b Everywhere: Stop using NonnullOwnPtrVector 
Same as NonnullRefPtrVector: weird semantics, questionable benefits.

Andreas Kling
8a48246ed1 Everywhere: Stop using NonnullRefPtrVector 
This class had slightly confusing semantics and the added weirdness
doesn't seem worth it just so we can say "." instead of "->" when
iterating over a vector of NNRPs.

This patch replaces NonnullRefPtrVector<T> with Vector<NNRP<T>>.

007767fc14 Shell: Convert builtins to use the modern main() style 
That is, return ErrorOr<int>, handle fallible ops with TRY() and accept
a Main::Arguments.
Note that we do not populate the argc/argv members of Main::Arguments,
so all accesses have to go through .strings.

4efc632e15 Shell: Allow the heredoc node to act as a redirection too

2a276c86d4 Shell: Start implementing a POSIX-compliant parser 
The parser is still very much a work-in-progress, but it can currently
parse most of the basic bits, the only *completely* unimplemented things
in the parser are:
- heredocs (io_here)
- alias expansion
- arithmetic expansion

There are a whole suite of bugs, and syntax highlighting is unreliable
at best.
For now, this is not attached anywhere, a future commit will enable it
for /bin/sh or a `Shell --posix` invocation.

6e7459322d AK: Remove StringBuilder::build() in favor of to_deprecated_string() 
Having an alias function that only wraps another one is silly, and
keeping the more obvious name should flush out more uses of deprecated
strings.
No behavior change.
