Deprecate uses_fp parameter in RTAPI and HAL APIs
All threads now unconditionally save and restore FPU/SSE state,
making the uses_fp parameter obsolete. Rather than removing it
from the API (which would break out-of-tree components), this
commit deprecates it with a grace period:
RTAPI: uses_fp parameter is accepted but ignored; FPU state is
always saved in rtapi_task_new() regardless of the value passed.
HAL: uses_fp parameter is accepted but ignored in
hal_export_funct(), hal_export_functf(), and hal_create_thread().
All functions and threads are always marked as FP-capable
internally. The addf FP compatibility check is removed since
all threads are now FP-capable.
halcompile: fp/nofp keywords in function declarations now emit
a deprecation warning and are treated as fp (always return 1).
The keywords will be removed in a future version.
Remove fp/nofp from all in-tree .comp files, conv.comp.in
template, and mkconv.sh generator. Remove fp1= from test .hal
files. Out-of-tree .comp files will still parse but emit a
deprecation warning.
Documentation: API man pages, tutorials, and guides updated with
deprecation notices. Removed references to FP thread restrictions
that no longer apply.
No API signatures changed — out-of-tree components continue to
compile unchanged but will see warnings from halcompile if they
use fp/nofp.
Based on patch by BsAtHome.
