stdatomic.h is available both in newlib and GCC include directories.
Normally (if you invoke the compiler without any flags) GCC include
directories are first on the list, so GCC’s stdatomic.h is used. In
IDF, we used to pass newlib include path as an extra include
directory, so newlib’s stdint.h got included instead.
Newlib 2.2.0 stdatomic implementation is compatible with -std=gnu99
but incompatible with -std=gnu11. And GCC doesn’t support atomic_load
with -std=gnu99 (it’s a C11 feature). So when we used atomic_load
with -std=gnu99, it worked due to newlib’s header.
Since we are no longer going to be including newlib headers into IDF,
GCC stdatomic will be used instead. Hence, add -std=gnu11 for source
files which use atomic features.
Operation:
In `esp_http_client_set_url`, we check for if old_host is same as new_host.
Delete and open new connection if host is different.
Issue:
We just pointed `client->connection_info.host` to `old_host` and reassigned it.
This made old_host and new_host always point to same location and hence, using old_host with new request.
Fix:
Made a separate copy for old_host using strdup.

Fixed adjtime function: While using the adjtime() function,
the time correction accumulated an error
when reading the time frequently (using gettimeofday).
1. remove redundant SPI clock settings, use rom functions to set clock.
2. remove redundant SPI cs setup and hold settings.
3. for old 32Mbit psram, cs hold time must only be 0.5T due to the special driving mode.(cs_setup = 0; cs_hold = 0)
4. for new 64Mbit psram, cs hold time is recommended to be 2.5T. (cs_setup = 1, cs_setup_time = 0;cs_hold = 1, cs_hold_time = 1)
1. Pass the correct conn_id to protocomm_req_handle
In transport_simple_ble_write(), passing param->exec_write.conn_id would
be invalid. Instead param->write.conn_id should be passed
Similar change in transport_simple_ble_exec_write() to use
param->exec_write.conn_id
2. simple_ble_start() assumes that the mode is BLE only and enables
Bluetooth controller accordingly. For, cases having BT + BLE like Alexa
(Provisioning over BLE + Audio over classic BT), this assumption should
be removed.
This fix prevents HTTP server from accepting new connections when the total count of connected
sockets has reached the max_open_sockets limit set during configuration. The pending connections
are kept in backlog until atleast one of the connected sockets is closed. The maximum number of
connection requests that can kept in backlog is specified as backlog_conn configuration option.
Note that this modification has no effect when LRU purge is enabled.
Also added sanity check on setting for max_open_sockets during configuration.

The task that runs the HTTP server can now be pinned to a particular core by setting `core_id`
in the HTTP server configuration. By default, the core is set to `tskNO_AFFINITY`, meaning
it can run on any core.

This uses a hack (temporarily defining __rtems__ from a wrapper header
file) to include timeradd, timersub, and similar macros, without
modifying newlib headers.
soc unit tests have not been included when compiling with CMake,
because ../${SOC_NAME}/test was not evaluated relative to the
CMakeLists.txt directory.
Also call register_components() regardless of the presence of test
directory for particular target.
This takes the code up to the latest released version of libcoap.
As there have been API changes, coap_client and coap_server in
examples/protocols have been updated to use the new APIs.
Further information on the new libcoap APIs can be found at
https://libcoap.net/doc/reference/4.2.0/
coap_client has been updated to handle BLOCK2 responses from
"coap://californium.eclipse.org"
coap_client has been modified to only send out one request (and wait for
the response)
coap_server has been updated to support Observe subscriptions, and well as
adding in PUT and DELETE handlers to work on the Espressif resource
coap_server and coap_client have had their stack sizes increased.
port/coap_io.c has been added, a copy of libcoap/src/coap_io.c with support
added for systems that do not have RFC 3542 section 20 support.
port/coap_io_socket.c has been removed as a lot of the code is now
replicated in different libcoap files.
Once this PR is place, then adding in DTLS will be a lot simpler (as a
separate PR)

GCC compiler can generate 8-bit stores when modifying bitfields of
volatile structs (https://github.com/espressif/esp-idf/issues/597).
In the specific case of I2C driver, this resulted in byte_num field
to be written using s8i. However the peripheral requires 32-bit
writes, and ignores 8-bit writes. This change modifies the code to
compose the 32-bit command register value first, and then write the
complete value to the hardware.

Linker script generator produces build/esp32/esp32.common.ld from
components/esp32/ld/esp32.common.ld.in
This works fine until IDF is downgraded to V3.1 which uses components/esp32/ld/esp32.common.ld and
doesn't track build/esp32/esp32.common.ld at all.
At this point, the linker runs in the build/esp32 directory and "-T esp32.common.ld" picks up the
linker script generated .ld file, which causes mis-builds.
As reported on forums: https://esp32.com/viewtopic.php?f=13&t=9684&p=40105
Removed as much branching (if statements) from the
gpio_intr_service ISR, as possible and split the while loop into
two. Also forced writing the two status*_w1tc variables only once,
instead of every time after calling the external function hooks.
The measurements below, was done using the following tools:
Toolchain version: crosstool-ng-1.22.0-80-g6c4433a
Compiler version: 5.2.0
Here follows a comparison of the gpio_intr_service ISR's
execution time, using a DS1054 oscilloscope. All the time spent
calling external functions, via the function pointers
gpio_isr_func[gpio_num].fn, were disregarded.

Issue: MDNS server initially sends probing packets to resolve naming confilicts with already registered service instances. In case of a conflict, instance name is altered and probing restarts. Original instance however wasnnot removed from the structure and upon service removal only one entry was removed and a dangling service might have been kept in the structure to bring about a crash.
Resolution: Keep only one instance of a service in the probing structure.
Closes IDF-498
possible race condition: user task runs mdns_init, which enables pcbs while mdns-task already created could execute enable/disable of the same pcbs if an appropriate system event received
mnds_free() initiates stop and delete timer tasks, which after locking the mutex could lead to a dead lock in case timer task executed before deleting the task, as it would wait indefinitelly for unlocking the mutex. This condition is fixed by calling _mdns_stop_timer without locking the mutex, because there's no need to protect any data when stopping and deleting the timer task
Closes https://github.com/espressif/esp-idf/issues/1696
Issue: mdns_service_add API allocates and queues an action to be processed in mdns task context; when allocation or queueing fails, allocated structure needs to be freed. Function _mdns_free_service did not only fee all the structures, but also updates packet data.
Resolution: Moved removal of packet data outside of _mdns_free_service function.
packets scheduled to transmit are pushed to action queue and removed from tx_queue_head structure, which is searched for all remaining services and while service is removed, then service questions/asnwers are also removed from this structure. This update fixes possible crash when packet is pushed to action queue, and when service is removed, its answers are removed from tx_queue_head, but not from action queue. this could lead to a crash when the packet is poped from action queue containing questions/answers to already removed (freed) service
Closes IDF-504
The current API is insufficient to allow the users to set different combinations of connection and discoverable mode
Users should be able to choose the device modes independently:
1. Connectable-
i. Non-connectable mode
ii. Connectable mode
2. Discoverable-
i. Non-discoverable mode
ii. Limited discoverable mode
iii. General discoverable mode
On flash program operation (either erase or write), if corresponding address has
cache mapping present then cache is explicitly flushed (for both pro and app cpu)
