A usbdev has only one serial string, so use a unique macro to control it.
For boards that enable board serial string using COMPOSITE_BOARD_SERIALSTR,
PL2303_BOARD_SERIALSTR, CDCACM_BOARD_SERIALSTR, USBADB_BOARD_SERIALSTR,
USBMSC_BOARD_SERIALSTR, and RNDIS_BOARD_SERIALSTR, they need to be replaced
with BOARD_USBDEV_SERIALSTR.

In usbclass_unbind, DEV_FREEEP is called first, and later
usbclass_freereq does not free memory due to ep NULL

unbind will call the adb_char_on_connect interface to wake up the adbd task,
adbd will then access the adb device and fail to return, at this time it will
close the adb device, we can do the final memory release operation in the
second unbind

iSerialNumber field in the device descriptor can be used to determining the
board when multiple boards connected to the same host. So add feature to change
serial string by board unique ID dynamically.
To use this feature, user must be implement the board_usbdev_serialstr() logic.

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.

* Simplify EINTR/ECANCEL error handling
1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx
* Unify the void cast usage
1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro

Ran nxstyle against many of the affected files. But this job was too big for today. Many of the network drivers under arch are highly non-compiant and generate many, many faults from nxstyle. Those will have to be visited again another day.
Author: Xiang Xiao <xiaoxiang@xiaomi.com>
This effects all network drivers as well as timing related portions of net/: devif_poll_tcp_timer shouldn't be skipped in the multiple card case. devif_timer will be called multiple time in one period if the multiple card exist, the elapsed time calculated for the first callback is right, but the flowing callback in the same period is wrong(very short) because the global variable g_polltimer is used in the calculation. So let's pass the delay time to devif_timer and remove g_polltimer.
