Merge branch 'master' into feature/menuconfig_cpu_frequency_option

Browse Source 
* master: (57 commits)
  components/lwip: fix grammar
  components/lwip: make SO_REUSE configurable via menuconfig
  bootloader: remove trailing newlines from log messages
  components/freertos: override per-task __cleanup handler to close stdin, stdout, stderr
  components/esp32: move peripheral symbols to separate ld script
  components/log: regroup macros for better readability
  gitlab-ci: allow running tests for branches, triggered via API
  components/log: fix timestamp calculation
  components/log: set default runtime log level to ESP_LOG_VERBOSE
  components/log: fix error when using ESP_LOGx from C++ code
  components/log: fix bugs, add options to override log level for files, components, and bootloader
  fix ledc and spi typo
  remove prefix and postfix
  Enable SO_REUSEADDR in LWIP
  freertos: fix memory debug macro issue Define configENABLE_MEMORY_DEBUG according to CONFIG_ENABLE_MEMORY_DEBUG
  peripheral structure headers: move volatile keyword from members to typedef
  Adding -fstrict-volatile-bitfields to the CFLAGS/CXXFLAGS. Without this, gcc tries to access bitfields using the smallest possible methods (eg l8i to grab an 8-bit field from a 32-bit). Our hardware does not like that. This flag tells gcc that if a bitfield is volatile, it should always use the type the field is defined at (uint32_t in our case) to size its access to the field. This fixes accessing the hardware through the xxx_struct.h headers.
  add peripheral  module struct headers
  build system docs: Add note about no spaces in component names
  Docs: Add note about unusual submodule messages when cloning on Windows

/**
* @brief Logging library
*
* Log library has two ways of managing log verbosity: compile time, set via
* menuconfig, and runtime, using esp_log_set_level function.
*
* At compile time, filtering is done using CONFIG_LOG_DEFAULT_LEVEL macro, set via
* menuconfig. All logging statments for levels higher than CONFIG_LOG_DEFAULT_LEVEL
* will be removed by the preprocessor.
*
* At run time, all logs below CONFIG_LOG_DEFAULT_LEVEL are enabled by default.
* esp_log_set_level function may be used to set logging level per module.
* Modules are identified by their tags, which are human-readable ASCII
* zero-terminated strings.
*
* How to use this library:
*
* In each C file which uses logging functionality, define TAG variable like this:
*
* static const char* TAG = "MyModule";
*
* then use one of logging macros to produce output, e.g:
*
* ESP_LOGW(TAG, "Baud rate error %.1f%%. Requested: %d baud, actual: %d baud", error * 100, baud_req, baud_real);
*
* Several macros are available for different verbosity levels:
*
* ESP_LOGE — error
* ESP_LOGW — warning
* ESP_LOGI — info
* ESP_LOGD - debug
* ESP_LOGV - verbose
*
* Additionally there is an _EARLY_ variant for each of these macros (e.g. ESP_EARLY_LOGE).
* These variants can run in startup code, before heap allocator and syscalls
* have been initialized.
* When compiling bootloader, normal ESP_LOGx macros fall back to the same implementation
* as ESP_EARLY_LOGx macros. So the only place where ESP_EARLY_LOGx have to be used explicitly
* is the early startup code, such as heap allocator initialization code.
*
* (Note that such distinction would not have been necessary if we would have an
* ets_vprintf function in the ROM. Then it would be possible to switch implementation
* from _EARLY version to normal version on the fly. Unfortunately, ets_vprintf in ROM
* has been inlined by the compiler into ets_printf, so it is not accessible outside.)
*
* To override default verbosity level at file or component scope, define LOG_LOCAL_LEVEL macro.
* At file scope, define it before including esp_log.h, e.g.:
*
* #define LOG_LOCAL_LEVEL ESP_LOG_VERBOSE
* #include "esp_log.h"
*
* At component scope, define it in component makefile:
*
* CFLAGS += -D LOG_LOCAL_LEVEL=ESP_LOG_DEBUG
*
* To configure logging output per module at runtime, add calls to esp_log_set_level function:
*
* esp_log_set_level("*", ESP_LOG_ERROR); // set all components to ERROR level
* esp_log_set_level("wifi", ESP_LOG_WARN); // enable WARN logs from WiFi stack
* esp_log_set_level("dhcpc", ESP_LOG_INFO); // enable INFO logs from DHCP client
*

* Log library — implementation notes.
*
* Log library stores all tags provided to esp_log_set_level as a linked
* list. See uncached_tag_entry_t structure.
*
* To avoid looking up log level for given tag each time message is
* printed, this library caches pointers to tags. Because the suggested
* way of creating tags uses one 'TAG' constant per file, this caching
* should be effective. Cache is a binary min-heap of cached_tag_entry_t
* items, ordering is done on 'generation' member. In this context,
* generation is an integer which is incremented each time an operation
* with cache is performed. When cache is full, new item is inserted in
* place of an oldest item (that is, with smallest 'generation' value).
* After that, bubble-down operation is performed to fix ordering in the
* min-heap.
*
* The potential problem with wrap-around of cache generation counter is
* ignored for now. This will happen if someone happens to output more
* than 4 billion log entries, at which point wrap-around will not be
* the biggest problem.

------------------
For components that have parts that need to be run when building of the
project is done, you can create a file called Makefile.projbuild in the
component root directory. This file will be included in the main
Makefile.
For components that have parts that need to be evaluated in the top-level
project context, you can create a file called Makefile.projbuild in the
component root directory. These files is included into the project's
top-level Makefile.
For example, if your component needs to add to CFLAGS for the entire
project (not just for its own source files) then you can set
``CFLAGS +=`` in Makefile.projbuild. Note that this isn't necessary for
adding include directories to the project, you can set
``COMPONENT_ADD_INCLUDEDIRS`` (see above) in the component.mk.

they can also reside in an other folder), the path to this may be
something like /home/myuser/projects/myprojects/components/httpd .
Components can have any name (unique to the project) but the name
cannot contain spaces (esp-idf does not support spaces in paths).
One of the things that most components will have is a component.mk makefile,
containing instructions on how to build the component. Because the
build environment tries to set reasonable defaults that will work most
of the time, component.mk can be very small.
