c7cd81bce8 LibSQL: Limit the number of nested subqueries 
SQLite hasn't documented a limit on https://www.sqlite.org/limits.html
for the maximum number of nested subqueries. However, its parser is
generated with Yacc and has an internal limit of 100 for general nested
statements.

Fixes https://crbug.com/oss-fuzz/35022.

d2662df57c LibC+AK: Remove our custom macros from <assert.h> 
Other software might not expect these to be defined and behave
differently if they _are_ defined, e.g. scummvm which checks if
the TODO macro is defined and fails to build if it is.

execute.

ed5777eb0a LibAudio: WavLoader: Avoid reading partial samples 
When samples are requested in `Audio::Loader::get_more_samples`,
the request comes in as a max number of bytes to read.

However, the requested number of bytes may not be an even multiple
of the bytes per sample of the loaded file. If this is the case, and
the bytes are read from the file/stream, then
the last sample will be a partial/runt sample, which then offsets
the remainder of the stream, causing white noise in playback.

This bug was discovered when trying to play 24-bit Wave files, which
happened to have a sample size that never aligned with the number
of requested bytes.

This commit fixes the bug by only reading a multiple of
"bytes per sample" for the loaded file.

3938b56577 LibAudio+LibCore: Remove unnecessary IODeviceStreamReader.h 
IODeviceStreamReader isn't pulling its weight.
It's essentially a subset of InputFileStream with only one user
(WavLoader).

This refactors WavLoader to use InputFileStream instead.

c3a60a5dcd LibGUI+SoundPlayer: Add Slider option to jump to cursor 
When the cursor is clicked outside of the slider knob,
the current behavior is that it will step up or down by the
Slider page step amount.

This commit adds an option to jump the slider knob
directly to the where the mouse cursor is on mouse down events.

This behavior is disabled by default. It must be enabled with
`Slider::set_jump_to_cursor()`.

Jump to cursor is enabled in SoundPlayer since most music players
have this behavior.
