e2e7c4d574 Everywhere: Use to_number<T> instead of to_{int,uint,float,double}
In a bunch of cases, this actually ends up simplifying the code as
to_number will handle something such as:

```
Optional<I> opt;
if constexpr (IsSigned<I>)
    opt = view.to_int<I>();
else
    opt = view.to_uint<I>();
```

For us.

The main goal here however is to have a single generic number conversion
API between all of the String classes.

5e1499d104 Everywhere: Rename {Deprecated => Byte}String
This commit un-deprecates DeprecatedString, and repurposes it as a byte
string.
As the null state has already been removed, there are no other
particularly hairy blockers in repurposing this type as a byte string
(what it _really_ is).

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.

9531abcb1a Shell: Add a "." builtin that aliases to "source" in POSIX
This patch adds an alias to the source builtin when an user types ".".
We cannot just add an enumeration entry using __ENUMERATE_SHELL_BUILTIN
because "." is not a valid name in a function.
This patch adds handling similarly to the name rewriting of ":".

This alias is limited to POSIX mode only.

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 :^)

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.

6e7459322d AK: Remove StringBuilder::build() in favor of to_deprecated_string()
Having an alias function that only wraps another one is silly, and

a492e2018d Userland: Silence warnings from ElapsedTimer::elapsed() type change
We changed elapsed() to return i64 instead of int as that's what
AK::Time::to_milliseconds() returns, causing a bunch of implicit lossy

casts.

0e26f2657e Shell: Add where builtin
The builtin is based on the behaviour of the z-shell.
Namely it tries to resolve every argument one by one.

When resolving (in the order below) the following results can occur:
  1. The argument is a shell built-in command. Then print it.
  2. The argument is an alias. In this case we print the mapped value.
  3. The argument was found in the `PATH` environment variable.
     In this case we print the resolved absolute path
     and try to find more occurences in the `PATH` environment variable.
  4. None of the above. If no earlier argument got resolved,
     we print the error `{argument} not found`.

If at least one argument got resolved we exit with exit code 0,
otherwise 1.

By not using Core::File to resolve the executable in the environment
but rather using a modified version of the code we print every
matching executable of the given name. This behaviour matches
up with the z-shell.

The builtin has the following flags to modify the behaviour according
to the users needs:
  - `-p --path-only`: This skips the built-in and alias checks
  (step 1 & 2)
  - `-s --follow-symlink`: This follows the symlinks of an executable to
  its symlink-free location.
  - `-w --type`: This displays the type of the found object
  without any additional descriptive information.

57dc179b1f Everywhere: Rename to_{string => deprecated_string}() where applicable
This will make it easier to support both string types at the same time
while we convert code, and tracking down remaining uses.

One big exception is Value::to_string() in LibJS, where the name is
dictated by the ToString AO.

6e19ab2bbc AK+Everywhere: Rename String to DeprecatedString
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)

5f99934dce Userland: Consolidate most PATH resolving into a single implementation
We previously had at least three different implementations for resolving
executables in the PATH, all of which had slightly different
characteristics.

Merge those into a single implementation to keep the behaviour
consistent, and maybe to make that implementation more configurable in
the future.
