Feature/btdm uart hci
1. support UART HCI, devolper need not to make a bridge between VHCI and UART.
2. fix bug of rand/srand called in ISR.
3. fix bug of BLE rx packets may cause assert.
See merge request !626

bt component: fix bluetooth gatt packets process bugs
1. Add process of prepare write request packets
2. Add process of execute write request packets
3. Add process of reliable write request packets
4. Fix bug of processing read blob request packets
5. Fix bug of processing write request packets
6. Optimize error check and process in stack
See merge request !558
add extra check before bluedroid init and disable
add extra check before bluedroid init and disable to avoid the mixed call cause unexpected errors.

component/bt : add adv/scan start complete event
1. indicate adv/scan start complete success or failed
2. controller do limit of adv/scan concurrence, so add some codes to report adv/scan start failed or not.
See merge request !524
component/bt:fixed the write ccc crash bug error
fix the gatt server write ccc lead to the system crash if not initialize the ccc value.
See merge request !515
1. indicate adv/scan start complete success or failed
2. controller do limit of adv/scan concurrence, so add some codes to report adv/scan start failed or not.
1. add new APIs bt controller enable/disab/deinit
2. make bt controller work need to call two APIs of esp_bt_controller_init and enable
3. modify phy init to make mac reset once
1. add a macro in menuconfig for users to choose whether store phy calibration data into NVS or not.
2. rename some disable phy and rf APIs so that existing code which calls old APIS will fail to compile.
1. Add disable PHY and RF when WiFi and BT are both disabled(including call sniffer disable API).
2. Do not init PHY and RF when cpu start. Init PHY and RF when call Wifi or BT start APIs(including sniffer enable API).
3. Add a temporary lib: librtc_clk.a and will delete it when CPU frequency switching function is done.
4. Add an function to get OS tick rate.
5. Do not put the whole pp.a in iram0, only put lmac.o, ieee80211_misc.o, ets_time.o and wdev.o in iram0.
This connection error caused by iPhone, it think that TX data length must large than 27 when slave support EXTEND_DATA_LENGTH. But this should be allow. Besides, the problem cannot be found on higher version of Iphone7, apple seemed to have fixed it.
Actually maybe other BLE device have the same problem.
