- don't do swapping if result is thrown away
- use correct return code if csd_ver is unknown
- use correct release function
When `heap_caps_malloc`/`heap_caps_calloc` are used for allocation,
`heap_caps_free` should be used to release allocated block.
The Key Manager hardware peripheral in its current form needs further
design changes before it can be offered as a production feature.
Until a revised peripheral design is available, withdraw ESP-IDF
support for it on all Key Manager capable targets.
riscv_trace_ll_enable_bus_clock and riscv_trace_ll_reset_register operate
on shared HP_SYS_CLKRST registers and were called concurrently from both
cores during SECONDARY init, creating RMW race conditions.
Move the clock/reset logic out of the HAL layer into
esp_riscv_trace_early_init, protected by PERIPH_RCC_ATOMIC() spinlock.
Wrap the LL functions with macros that enforce the caller must be inside
a PERIPH_RCC_ATOMIC() critical section at compile time.
In the Bluetooth connections with some smartphones, communication can possibly be blocked
during packet type negotation, when ESP32-S31 attempts to finalize the ACL-U transmission
and waits for the last Tx ACL-U packet to be transmitted, but peer device rejects the
packet with FLOW=STOP in its packet, thus causing a deadlock.

Allow specifying extra compiler flags (warning flags, preprocessor
definitions, etc.) via a new 'compile_options' entry in the
idf-build-file frontmatter. The options are applied to the source
file via target_compile_options in the generated main component
CMakeLists, with CMake quoting so that flags like -DMSG="hello world"
reach the compiler exactly as written.

Add a new idf.py extension that allows building standalone C files
without requiring full project boilerplate. Source files can include
optional YAML frontmatter in block comments to specify sdkconfig
options, component dependencies, and target configuration.
When the frontmatter configuration changes, the stale sdkconfig is
removed so the new defaults are applied, and a target change also
clears the build directory since IDF_TARGET is pinned in the CMake
cache.

When a loop is deleted while an internal legacy "cleanup" event is still
queued (posted by a deferred self-unregistration from within a handler),
esp_event_loop_delete() drained the queue but only freed the post payload,
leaking the heap copy of the handler context allocated for the legacy path.
Free ctx->handler_ctx for queued legacy cleanup events while draining the
queue, mirroring the cleanup done in esp_event_loop_run().
Add a regression test that leaves a legacy cleanup event queued and asserts
no memory is leaked on loop deletion.
When esp_event_loop_run() exited via the ticks-expired break path,
loop->running_task was left pointing to the current task handle.
Any subsequent trylock in esp_event_handler_unregister_with_internal()
would see a stale non-NULL running_task and take the wrong code path.
esp_event_post_to() could access loop->queue / loop->mutex after
esp_event_loop_delete() freed them when both ran concurrently.
Introduce esp_event_loop_state_t with:
- posts_in_flight: reference-count incremented atomically (under
state.lock spinlock) before touching any loop resources, decremented
on every exit path via goto on_err.
- deleting: atomic_bool set by esp_event_loop_delete() to block new
posts from entering the critical section.
esp_event_loop_delete() sets deleting=true, then busy-waits (releasing
and re-acquiring loop->mutex each tick) until posts_in_flight reaches
zero before proceeding with teardown.
esp_event_isr_post_to() performs a lock-free atomic_load of deleting as
a best-effort guard; ISR context cannot participate in the spinlock
protocol but the window is documented and accepted.
