The new configuration CONFIG_USBMSC_NOT_STALL_BULKEP avoids to go into
stall state when :
- Receiving SCSI_CMD_INQUIRY with flags or pagecode != 0
- Receiving SCSI_CMD_MODESENSE6 and return the result data shorter than
the requested data size.
Instead of stall, it just ignores the error condition.
Originally the usb driver goes into the stall under the conditions
mentioned above to inform to the USB host that the requested SCSI feature
is not supported, or the result data is shorter than the requested data
size.
But, at this moment, RP2040 USB device driver cannot handle entering and
leaving stall state of the bulk endpoints well. Once stalls, the host -
device communication stops and cannot be resumed.
I have investigated to solve the issue and found that the existing
RP2040 USB device driver implementation, TinyUSB
(https://github.com/hathach/tinyusb) mass-storage class driver doesn't
enter the stall state like the treatment of this patch.
So, I introduce this new configuration as the RP2040 workaround.
In the future, when the RP2040 USB device driver is fixed and can handle
the bulk endpoint stall correctly, this patch should be reverted.

Previous fix to RNDIS response queueing caused unaligned access
to response buffer in some configurations. On ARM Cortex-M, this
would cause hardfault if optimizer used strd instruction.
Fix by allocating the buffer as uint32_t. RNDIS messages are always
a multiple of 4 bytes in size, so this ensures alignment.
Gracefully handle output queue full conditions. This shouldn't happen
in practice as the host is supposed to limit the number of commands
simultaneously in execution.
Reset the response queue on RNDIS_RESET_MSG. This way communication
can recover even if host and device get out of sync.
Sometimes Windows would send RNDIS_KEEPALIVE_MSG and RNDIS_QUERY_MSG close
to each other. This would cause the latter command to overwrite the reply for
the prior command. This in turn will cause Windows to drop the connection after
a 20 second timeout.
Easy way to reproduce the issue is to open the Windows "Adapter Status" dialog that
shows the realtime TX/RX byte counts. This causes multiple RNDIS_QUERY_MSGs per
second, and the connection will drop in less than an hour.
This commit fixes this issue, and other potential race conditions (such as USB
descriptor read in middle on RNDIS query) by using a separate queue for the reply
packets.

Resolution of Issue 619 will require multiple steps, this part of the first step in that resolution: Every call to nxsem_wait_uninterruptible() must handle the return value from nxsem_wait_uninterruptible properly. This commit is only for rwbuffer.c and those files under drivers/serial, drivers/timers, and drivers/usbdev.
This commit completes that step for all of the files under drivers/. Still remaining: All of the files under arch/.
This reverts commit b9ace36fcc.
This change was added by PR 625 but has a serious logic flaw. It removes all occurrences of INCDIROPT and replaces it with a definition in tools/Config.mk:
else ifeq ($(WINTOOL),y)
DEFINE = "$(TOPDIR)/tools/define.sh"
INCDIR = "$(TOPDIR)/tools/incdir.sh" -w
This logic flaw is the Config.mk is included in all Make.defs files BEFORE WINTOOL is defined. As a result, the definition is wrong in many places when building under Cygwin with a Windows native toolchain.
