Passed GreenTea CI.
Added RZ_A2XX and GR_MANGO to targets.json.
Added RZ_A2XX to mbedlib.json in lwipstack and netsocket/ppp.
Added TARGET_RZ_A2XX directory to targets/TARGET_RENESAS.
Added TARGET_RENESAS_EMAC directory to features/netsocket/emac-drivers.
Moved TARGET_RZ_A1_EMAC directory into the TARGET_RENESAS_EMAC directory below and renamed to TARGET_RZ_A1XX.
Added TARGET_RZ_A2XX directory to features/netsocket/emac-drivers/TARGET_RENESAS_EMAC.
Added argument-check to avoid accessing NULL pointer.
The second argument 'interface_name' of this function can be NULL.
And the argument 'interface_name' is used for the argument of strcmp() without checked.
For example, LWIP::add_dns_server() calls dns_getserver(index - 1, NULL).
- Public headers moved into mbed-os/connectivity/lwipstack/include/lwipstack folder
- Source moved into mbed-os/connectivity/lwipstack/source folder
- Internal lwip and lwip-sys libraries moved to source folder
