When devif_loopback handles a packet (like a ping targeting at this dev), it does not call the txdone callback, breaking the tx pipeline and may left some packets unhandled, delayed until next transmit on the network interface.

Share one worker between multiple simulated network devices may work most of the time, but sometimes breaks the tx pipeline when sending packets on more than one interface at the same time, and leaves some packets unprocessed in network stack, delayed until next transmit on the network interface. The rx process is likely delayed in packet processing under similar situation, so keep g_avail_work and g_recv_work the same number as interfaces.

Use CONFIG_ARCH_CHIP_QEMU instead of CONFIG_ARCH_CHIP_QEMU_A53. This is because these configurations depend on the hardware configuration of qemu (memory map, irq numbers, etc.).

Support more than one TAP device for debugging (future) NAT and FORWARD, left WPCAP and VPNKit unchanged (force number to 1).
Although we can support at most 31 interfaces, limit to 8 like CONFIG_TUN_NINTERFACES.

1. rename arm_backtrace_thumb.c to arm_backtrace_sp.c
2. use EHABI stack unwinder instead of instruction unwind

Make a separate config flag for enabling L2 cache. This is on by
default when compiling a standalone/bootloader configuration, but
can also be disabled for special cases, such as memory testing

The default size in QEMU system is 128MB, and the size specified in chip.h is also 128MB. However, the region size for MMU was 512MB, so fixed it.
