igmp: Refresh the ip header pointer after m_pullup()
There is a chance that the m_pullup() call immediately above invalidated
the "ip" pointer, so refresh it as we do with the IGMP header.
Otherwise the test in igmp_input_v3_query() for whether the packet is an
IGMPv3 general query might use a pointer to a freed mbuf.

pf: deregister the ifnet_rename_event handler on unload
pfi_initialize() registers pfi_rename_ifnet_event() on
ifnet_rename_event, but pfi_cleanup() never deregisters it. After
"kldunload pf", the next interface rename calls through a stale
pointer into the unloaded module:
kldload pf
kldunload pf
ifconfig epair create
ifconfig epair0a name foo

Mk/bsd.gecko.mk: set BINDGEN_FLAGS to find dependencies
cbindgen now needs to find ports' includes. This affects all gecko
ports, so set this globally.

[offload][omp] Load and resolve device binaries through liboffload
Migrate DeviceTy::loadBinary and global/kernel symbol resolution off
GenericPluginTy::load_binary/get_global/get_function onto liboffload's
Program/Symbol API, encapsulated in a new ProgramTy abstraction that wraps
an ol_program_handle_t. Kernel symbol resolution still needs the plugin's
opaque GenericKernelTy* handle for the legacy launch path, obtained via a
temporary __ol_tgt_GetKernelFromSymbol helper rather than new public
liboffload API surface. Removes the now-dead __tgt_device_binary type and
the corresponding GenericPluginTy methods and exports entries.
[offload][omp] Route RPC callback registration through liboffload
Replace __tgt_register_rpc_callback's direct iteration over plugins
with olIteratePlatforms + olPlatformRegisterRPCCallback, and drop the
now-unused RPCServerTy::registerCallback export. Move the
initialized/has-devices guard that used to live in libomptarget into
olPlatformRegisterRPCCallback_impl.
[offload][omp] Query device info directly through liboffload
Route DeviceTy::getInfo through olGetDeviceInfo instead of the
plugin's obtain_device_info, and drop the now-unused
GenericPluginTy::obtain_device_info wrapper and its liboffload
export.
[offload][omp] Manage memory allocation through liboffload
Migrate DeviceTy::allocData/deleteData off GenericPluginTy::data_alloc/
data_delete onto liboffload's olMemAlloc*/olMemFree, migrate
targetLockExplicit/targetUnlockExplicit off data_lock/data_unlock onto
olMemRegister/olMemUnregister (fixing a latent bug where these passed
the OpenMP-visible device number instead of the plugin device id), and
migrate DeviceTy::isAccessiblePtr onto a new olMemIsAccessible API
(added with a unit test) since liboffload had no equivalent for
querying accessibility of arbitrary, not-necessarily-liboffload-
allocated pointers. Removes the now-dead GenericPluginTy::data_alloc/
data_delete/data_lock/data_unlock/is_accessible_ptr wrappers and their
exports entries.
[offload][omp] Remove data_fence
All supported backends execute enqueued work on a given queue in
submission order (CUDA, AMDGPU, and Host queues are always in-order;
Level Zero's default and non-default in-order/synchronous command
modes are as well), so the explicit data-fence used to order a
pointer-attachment after prior data transfers is unnecessary. Remove
the DeviceTy/GenericDeviceTy/GenericPluginTy dataFence chain and the
now-unused olQueueBarrier liboffload API added to support it.
[OFFLOAD] add olIteratePlatforms (#226439)
Add a new service to iterate created Platforms. This differs from
obtaining the platforms from the existing olIterateDevices in that the
platforms are not initialized.
