The line history is unavailable if the alternate screen buffer is
currently enabled. However, since TerminalWidget uses the history size
to offset its line numbers when rendering, it will try to render
inaccessible lines once the history is not empty anymore.
When attempting to write to a socket that is not connected or - for
connection-less protocols - doesn't have a peer address set we should
return EPIPE instead of blocking the thread.
Previously, AK::Function would accept _any_ callable type, and try to
call it when called, first with the given set of arguments, then with
zero arguments, and if all of those failed, it would simply not call the
function and **return a value-constructed Out type**.
This lead to many, many, many hard to debug situations when someone
forgot a `const` in their lambda argument types, and many cases of
people taking zero arguments in their lambdas to ignore them.
This commit reworks the Function interface to not include any such
surprising behaviour, if your function instance is not callable with
the declared argument set of the Function, it can simply not be
assigned to that Function instance, end of story.
According to the definition at https://sqlite.org/lang_expr.html, SQL
expressions could be infinitely deep. For practicality, SQLite enforces
a maxiumum expression tree depth of 1000. Apply the same limit in
LibSQL to avoid stack overflow in the expression parser.

The specification requires that we immediately return Infinity during
the iteration over the arguments if positive or negative infinity is
encountered, and return a NaN if it is encountered and no Infinity was
found. The specification also requires all arguments to be coerced into
numbers before the operation starts, or else a number conversion
exception could be missed due to the Infinity/NaN early return.

The PCRE JIT creates memory that needs to be readable, writable and
executable at the same time. Serenity does not like this, so disable
it. This JIT is of limited use for the current applications of PHP
within Serenity anyway :-)
Previously, we would echo characters back just as they were passed to
us, even in canonical mode. This caused newlines to not work correctly
in some programs.

When clicking on the TreeView in profiler without selecting a node and
then pressing up or pgup, cursor_index was in an invalid state. Instead
select the first node in the index.
On most (if not all) systems rm ignores an empty paths array if -f or
--force is specified. This helps with scripts that may pass an empty
variable where the file paths are supposed to go.
This changes URL parser to use the 0xFFFFFFFF constant instead of 0 to
indicate end of file. This fixes a bug where inputs containing null
bytes would terminate the parser early, because they were interpreted
as end of file.
This patch adds a state_name method to URLParser to convert a state to a
string. With this, the debugging statements now display the state names.
Furthermore, this fixes a bug where non-ASCII code points were
formatted as characters, which fails an assertion in the formatting
system.
Because non-ASCII code points have negative byte values, trimming away
control characters requires checking for negative bytes values.
This also adds a test case with a URL containing non-ASCII code points.

TMPDIR This variable shall represent a pathname of a directory made
available for programs that need a place to create temporary
files.
Ports like PHP benefit from having this environment variable set, and
there exist a lot of scripts that assume the presence of such an
environment variable.
