0e1bd54896 Shell/PosixParser: Correctly parse the OR_IF token 
This fixes an unfortunate typo where we would parse the OR_IF token as
an AST::And node. Now, it is parsed into an AST::Or node :^).

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.

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.

a2f60911fe AK: Rename GenericTraits to DefaultTraits

Previously, the shell would enter an infinite loop when attempting to
parse a heredoc entry within a `$(` command substitution.

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.

`"$@"`, this commit makes us support that.

9e978c6cd1 Shell: Recognise the (seemingly) bash-specific <<\WORD heredoc key 
Bash eats the backslash in this format (similarly for W\ORD etc.).
Dr.POSIX doesn't specify this anywhere, but it's used all over the
place, so let's support it.

ba4db899d4 LibSyntax+Userland: Make LibSyntax not depend on LibGUI 
This moves some stuff around to make LibGUI depend on LibSyntax instead
of the other way around, as not every application that wishes to do
syntax highlighting is necessarily a LibGUI (or even a GUI) application.

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.

1453028975 Shell: Color bareword yellow if it's a prefix of at least one command 
Before, if a bareword wasn't a runnable program's filename it got
colored red and white otherwise. Now, additionally it will be checked if
it is a "prefix" of a possible command and colored yellow if it is and
red if not.

Coloring this way provides another "feedback" to the user: If while
typing out a command name the color changes from yellow to red then a
typo occurred :^)

To check if a bareword is a prefix the `Shell::complete_program_name()`
function is utilized (if pressing tab gives you some suggestions then it
is a prefix).

b6d7c5fb0e Shell: Correctly track nested expansions in POSIX mode 
Previously any expansion closing sequence would've caused the entire
expansion chain to be terminated, fix this by keeping track of active
expansions and running the parser in 'skip' mode.

Fixes #19110.

8751be09f9 AK: Serialize URL hosts with 'concept-host-serializer' 
In order to follow spec text to achieve this, we need to change the
underlying representation of a host in AK::URL to deserialized format.
Before this, we were parsing the host and then immediately serializing
it again.

Making that change resulted in a whole bunch of fallout.

After this change, callers can access the serialized data through
this concept-host-serializer. The functional end result of this
change is that IPv6 hosts are now correctly serialized to be
surrounded with '[' and ']'.
