This also adds a 'math' immediate function that can be used in Shell
proper to do arithmetic stuff.

359d6e7b0b Everywhere: Stop using NonnullOwnPtrVector

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>>.

500044906d LibCore+Everywhere: Remove ArgsParser::add*(char const*&) 
This is not guaranteed to always work correctly as ArgsParser deals in
StringViews and might have a non-properly-null-terminated string as a
value. As a bonus, using StringView (and DeprecatedString where
necessary) leads to nicer looking code too :^)

51c3967516 Everywhere: Use '_{short_,}string' literals more 
This mostly updates code what was written before but merged after these
were added.

db886fe18b Userland+AK: Stop using getopt() for ArgsParser 
This commit moves the implementation of getopt into AK, and converts its
API to understand and use StringView instead of char*.
Everything else is caught in the crossfire of making
Option::accept_value() take a StringView instead of a char const*.

With this, we must now pass a Span<StringView> to ArgsParser::parse(),
applications using LibMain are unaffected, but anything not using that
or taking its own argc/argv has to construct a Vector<StringView> for
this method.

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.

a6d77162f4 Shell: Correctly keep track of special parameter length 
We were previously treating special expansions (e.g. $#) as zero-length
expansions, which made the shell repeat them literally after expanding
them.

Ali Mohammad Pur
beaae6b420 Shell: Use the POSIX parser if run as /bin/sh or passed the --posix flag 
Note that the default shellrc is most likely not valid posix sh code, so
passing --skip-shellrc is suggested until we come up with a separate
shellrc file for the POSIX parser to use when interactive.

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.
