Backporting the project.diff from OBS

* All previous versions of fluidsynth have incorrectly rejected
    Soundfont files with unknown INFO subchunks.
  * Fix incorrect GS DT1 SysEx checksum validation.
  * Fix a NULL pointer dereference during legato mono playing.

-- Update to version 2.5.2:
-  * The CoreAudio driver has gained iOS support
-  * Improve error handling and reporting when loading default
-    soundfont
-  * Improve logging and side-effect mitigation when basic channel
-    configuration changes
-  * Fix CVE-2025-68617 - a heap-based use-after-free involving DLS files
-    (GHSA-ffw2-xvvp-39ch) (bsc#1255519)

-
-- Update to version 2.5.1
-  * Previous versions have incorrectly exposed private C++ and
-    inline symbols; they are now hidden from the library.
-  * Fluidsynth now resets DataEntry values when it receives
-    (N)RPN MSB/LSB to prevent off-tuned channels.
-  * Fix a regression introduced in 2.5.0, that could have caused a
-    NULL pointer deref when playing AWE32 NRPN MIDIs.
-  * Fix a regression introduced in 2.5.0, that caused convex
-    unipolar modulators to use a concave mapping.
-  * Fix a regression introduced in 2.4.6, which in rare cases
-    could have caused the cutoff frequency of the IIR filter to
-    get stuck or change abruptly.
-  * Fix a build issue where fluidsynth was trying to find glib
-    even when it shouldn't.
-  * Fix typos in ALSA log messages.

-- Update to version 2.5.0
-  New Features
-  * Add a C++11-based OS abstraction layer as a replacement for
-    glib, bringing these minor limitations when C++17 is
-    unavailable.
-  * Add native support for Downloadable Soundfont Format.
-  * Fluidsynth now recognizes the DMOD INFO-subchunk.
-  * A new positional flag has been introduced: -b, --bank-offset
-  Breaking Changes
-  * Support for SDL2 has been removed - pls. use SDL3 instead.
-  * The processing order of fluidsynth's configuration files has
-    been changed (#1573, refer to wiki for details).
-  * The legacy shell commands for reverb and chorus have been
-    removed (#1659, refer to UserManual for details).
-  Musically Breaking Changes
-  * It was discovered that fluidsynth was mapping some modulators
-    slightly inaccurately into their normalized range.
-  * Some Roland GS NPRN Params are now mapped to CC numbers.
-  * Fluidsynth now auto-detects whether Portamento Time is 7bit
-    or 14bit wide - this fixes the infamous Descent Game08 tune.
-  * Previously, fluidsynth's default behavior was to use
-    portamento only for those notes, that were played in a
-    successive / legato manner; to further improve the portamento
-    experience, this was changed and fluidsynth now plays
-    portamento for all notes by default.
-  Other Changes
-  * Fix drum kits not always being selected after SysEx GS Rythm
-    Part.
-  * The logic for parsing INFO chunks has been revised to improve
-    handling of unknown INFO-subchunks.
-  * Fix a race condition in fluid_synth_alloc_voice() public API
-    function (#1664).
-  * Fix installing static and shared libs cmake targets on the
-    same prefix (#1648).
-- Support for GLib and libinstpatch is deprecated.
-  * build with "-Dosal=cpp11 -Denable-libinstpatch=0"

-- Update to version 2.4.8
-  * Fix systemd daemon failing with spaces in Soundfont filenames.
-  * Fluidsynth now explains why it discards invalid generators when
-    run in verbose mode.
