526d0eef0d wavparse: Fix clipping of size to the file size 
The size does not include the 8 bytes tag and length, so an additional 8 bytes
must be removed here. 8 bytes are always available at this point because
otherwise the parsing of the tag and length right above would've failed.

85969fdaa7 level: Fix integer overflow when filling LevelMeta 
The level in GstAudioLevelMeta is represented as a signed 8bit value from 0 to
127 (with 127 meaning silence). When converting from double, make sure to clip
the value, this also prevent integer overflow in the conversion. This fixes an
issue where a lower then -127db is reported and random level with near silent
streams (due to integer overflow).

fbad7b593d validate-scenario: Fix busy waiting, missing lock 
execute_next_action_full() logs that it removes the source when an
action returns ASYNC, but the code for that was incomplete, as it was
setting source_id to zero but not actually removing the source.

This lead to execute_next_action_full() being run continuously, only
alliviated by the default 10ms interval in the GSource from
`scenario->priv->action_execution_interval`.

This patch fixes that. As a drive-by fix it also adds locking to one
remaining unlocked usage of `priv->execute_actions_source_id`.

835bc0eef2 validate.py: Fix warning about wrong escape 
There were a couple strings containing \(. That is not a valid escape
sequence in Python. The escape sequence was meant for GStreamer, and as
such either the backslash should be doubled or a raw string must be
used. This patch uses the latter for readability.

Python 3.13 will print a warning when a invalid escape sequence in a
string is found.

As a drive-by fix, this patch fixes fixes whitespace issues in the file
to make the Python linter happy.
