ddbe6bd7b4 Userland: Rename Core::Object to Core::EventReceiver 
This is a more precise description of what this class actually does.

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).

da7bf5f785 Shell: Add support for the '!' POSIX pipeline prefix 
This prefix simply inverts the exit code of the pipeline, which we
implement using the 'not' builtin.

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 ']'.

1c1aa2c0d0 Shell: Handle (most) errors in the parsers 
This turns all errors into either "OOM" or a proper shell error (if
propagation is impossible or meaningless).
Fixes `echo -en '\xfe\x4a' | $SHELL` crashing.

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.

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.
