880d78f903 sendfile: Fixed behavior of sendfile when count is set to zero. 
If sendfile() is called with a zero count, it will nevertheless
try to send the data. This is mostly meaningless, it causes
waste of resources, and in some cases delays.

This commit adds special handling for this case, allowing
sendfile to return immediately zero. The new behavior is
in line with the Linux variant of sendfile.

4ae17a6f7b sched:Automatically find deadlocks when assert 
When asserting, automatically analyze whether
there is a deadlock in the thread, and if there
is a deadlock, print out the deadlocked thread.

The principle is to analyze whether there is
a lock ring through the tcb holder.

5e7ce13b3e drivers: virtio: Use one dscriptor for RX in virtio-mmio-net.c 
Summary:
- In this implementation, only one descriptor is used for RX.
- NOTE: we still use two descriptors for TX

Impact:
- None

Testing:
- Tested with qemu-7.1

5b90ae9c72 boards/samv7: add lower level IOCTL handler to sam_gpio_enc driver 
SAMv7 encoder driver with GPIO pins was written without IOCTL support.
While this driver does not require any lower level IOCTLs for its
functionality the upper layer fails on assertion when unknown command
can not be send to lower layer. This commit adds IOCTL handler that
always returns -ENOTTY as no commands are supported.

da319bbd85 riscv/addrenv: Move addrenv_switch() to correct place after FPU change

35c27b5a9a riscv/fpu: Restore correct lazy-FPU functionality 
- Save the FPU registers into the tcb so they don't get lost if the stack
  frame for xcp.regs moves (as it does)
- Handle interger and FPU register save/load separately
- Integer registers are saved/loaded always, like before
- FPU registers are only saved during a context switch:
  - Save ONLY if FPU is dirty
  - Restore always if FPU has been used (not in FSTATE_OFF, FSTATE_INIT)
- Remove all lazy-FPU related logic from the macros, it is not needed

040eb3c990 riscv/swint: Give the full tcb to the context switch routine 
Why? The tcb can contain info that is needed by the context switch
routine. One example is lazy-FPU handling; the integer registers can
be stored into the stack, because they are always stored & restored.

Lazy-FPU however needs a non-volatile location to store the FPU registers
as the save feature will skip saving a clean FPU, but the restore must
always restore the FPU registers if the thread uses FPU.
