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.
Acquires PM_APB_FREQ_MAX lock when carrying any transaction on I2S if
Power Management Framework is enabled.

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.
With OPTIMIZATION_FLAGS = -Og, 1.34 uSeconds faster:
3.22 uSec (with this patch)
4.56 uSec (with commit 71c90ac4)
100 - (100 * 4.56 / 3.22) = 42% faster
With OPTIMIZATION_FLAGS = -Os, 1.65 uSeconds faster:
2.89 uSec (with this patch)
4.54 uSec (with commit 71c90ac4)
100 - (100 * 4.54 / 2.89) = 57% faster
