b3be1b5190 tcpip_adapter: make log output at debug level less noisy 
At debug log level, tcpip_adapter would print logs for each function
call scheduled onto the tcpip task. These logs contained pointers which
idf_monitor decoded, adding even more noise and useless vertical space
in logs. This change moves these log statements to verbose level.

b7fc067c8c heap: Fix bug when realloc moves data between heaps 
When realloc-ing to a smaller buffer size which ends up allocated in a different heap, the heap
structure is corrupted. This can only happen:

* If heap checking is Comprehensive (meaning buffers are never shrunk in place) and the heap the buffer was originally allocated in is full.
* Calling heap_caps_realloc() to deliberately move a buffer to a different capabilities type, and shrink it at the same time.

Probable fix for https://github.com/espressif/esp-idf/issues/1582
Probably the same issue:

70ab924dbb Especially when internal memory fills up, some FreeRTOS structures (queues etc) get allocated in psram. These structures also contain a spinlock, which needs an atomic-compare-swap operation to work. The psram hardware, however, does not support this operation. As a workaround, this patch detects these spinlocks and will, instead of S32C1I, use equivalent C-code to simulate the behaviour, with an (internal) mux for atomicity. 2018-02-02 17:11:06 +08:00

750c8c00c8 This is a fix for the esp_log_level_set function. The problem is when this 
function is called but NOT withe the same 'c' string constant that the LOG*
calls used in each module, the cache check doesn't match, so the cached
entry won't get updated. There's no point in optimizing this function
anyway because it is only called rarely.

Fix `#if (LOG_LOCAL_LEVEL >= ESP_LOG_INFO)` which is always false and
produces a warning with -Wundef.

Use same pattern to compare LOG_LOCAL_LEVEL with ESP_LOG_INFO as is used
in definition of `ESP_LOG_BUFFER_HEX_LEVEL` and
`ESP_LOG_BUFFER_CHAR_LEVEL`.

Also reformat existing definitions for better readability.

90c9ffa975 component/bt: free timer resources after using them 
Bluedroid use a set of timer function pairs such as btu_start_timer/btu_stop_timer, btu_sys_start_timer/btu_sys_stop_timer for use, in a lack of timer release functions. Thus the timers may be exhausted after some event sequence such as repetition of connection/reconnection with different devices. The maximum timer number used in bluedroid is given by ALARM_CBS_NUM which is 30 for now. This bugfix borrowed some update from bluedroid in Andoroid 7.0, which add timer release functions which promote the recycle of timer resources.

870efdb9d4 bugfix(uart): patten detect function 
requirement from github(https://github.com/espressif/esp-idf/issues/805): to provide the position in the buffer of the pattern detected.

requirement from AT application: in AT app, when no hardware flow control is enabled, in some situation the rx buffer might be full, and the terminator “+++” might be lost, we can use pattern detect interrupt to avoid missing the terminator. When pattern detect interrupt happens, it will not send a data event at the same time.

1. Add API to get position of detected pattern in rx buffer
2. Modify UART event example
3. Add comments for uart_flush, add alias API uart_flush_input to clear the rx buffer
4. Modify the way rx_buffered_len is calculated
