Steve Lhomme 49ab34dfef [CMake] disable fseeko on 32-bit Android before API 24 
It can be linked in the NDK so check_function_exists detects it. But it's only supporting _FILE_OFFSET_BITS=64
since Android API 24 [1].

With NDK 26 it's no longer possible to build assuming the API is always available.

Improve failure handling when multithreading (#681) 
In case of encoder failure within a thread, asserts were false
and a locked mutex would be destroyed. This fix leaves in a race
condition: encoder->protected_->state is written without a lock.

Refind import cuesheet op after appending seekpoints (#677) 
This fixes a heap-use-after-free. The free was part of a realloc,
and the cuesheet op handle was still pointing to the old
allocation

flac: foreign_metadata: fix -Walloc-size (#654) 
GCC 14 introduces a new -Walloc-size included in -Wextra which gives:
```
src/flac/foreign_metadata.c:803:33: warning: allocation of insufficient size ‘1’ for type ‘foreign_metadata_t’ with size ‘64’ [-Walloc-size]
```

The calloc prototype is:
```
void *calloc(size_t nmemb, size_t size);
```

So, just swap the number of members and size arguments to match the prototype, as
we're initialising 1 struct of size `sizeof(foreign_metadata_t)`. GCC then sees we're not
doing anything wrong.

Fix format ending up with wrong subformat (#676) 
It was possible the format was taken from foreign metadata and the
subformat from command-line options.

fix invalid C23 in process_frame_thread_ (#649) 
process_frame_thread_ should return NULL instead of false,
in C23 NULL and _Bool are not compatible and the code is rightfully
rejected by the compiler.

‘_Bool’ but ‘void *’ was expected"
