netconn_gethostbyname: Fix race reporting success
If the DNS request is dispatched and performed very quickly,
then it can complete before tcpip_callback() actually returns,
in which case we'll destroy the actual err_t error value passed
in the message. Use a local variable for the tcpip_callback
error code so that can't happen.

kconfig: define ESP32_PHY_MAX_TX_POWER if PHY_ENABLED
ESP32_PHY_MAX_TX_POWER option is only meaningful for WiFi, so previous
change made it depend on WIFI_ENABLED. However if WiFi is not enabled,
but BT is, this option becomes undefined which breaks phy_init_data
generation.
This change turns ESP32_PHY_MAX_TX_POWER into a hidden parameter, which
depends on PHY_ENABLED. New user-visible parameter,
ESP32_PHY_MAX_WIFI_TX_POWER is introduced which depends on WIFI_ENABLED
and is used as default value for ESP32_PHY_MAX_TX_POWER if WIFI_ENABLED
is set. Otherwise ESP32_PHY_MAX_WIFI_TX_POWER is set to 20.

fixes for issues observed when using spi_flash

when operations on unpinned tasks are performed.
The issue is reported in https://github.com/espressif/esp-idf/pull/258
- esp_intr_noniram_disable doesn’t disable interrupts when compiled in
release mode. This issue manifested itself with an illegal instruction
exception when task WDT ISR was called at the time when flash was
disabled.
Fixes https://github.com/espressif/esp-idf/issues/263.
- Tick hooks on CPU1 were not called if CPU0 scheduler was disabled for
significant amount of time (which could happen when doing flash erase).
The issue manifested itself as “INT WDT timeout on core 1” error.

freertos: call tick hooks on CPU1 even if CPU0 scheduler is suspended
The block which dispatches ticks on CPU1 was a copy of the code block
for the normal path (CPU0). It used to check uxPendedTicks, with the
logic that uxPendedTicks can be 0 iff the scheduler is not suspended.
On CPU1 however, uxPendedTicks is not related to the state of the
scheduler (as uxPendedTicks is updated on CPU0). Due to this, if CPU0
scheduler was suspended, and uxPendedTicks happened to be nonzero,
tick hooks on CPU1 didn’t run, even though CPU1 scheduler was working.
This change removes the check for uxPendedTicks in CPU1 code path,
so that the tick hooks on CPU1 always get called (as for the CPU0 code
path).

intr_alloc: mark inline asm operand as earlyclobber
When compiling in release mode, compiler was choosing same register for
oldint and intmask variables, so INTENABLE was never modified.
This effectively broke disabling of non-IRAM interrupts during flash

This change adds an extra constraint tells the compiler that output
operand should not be placed into the same register as an input one.

Merge branch 'feature/parse_unit_test_cases_from_test_files' into 'master'
Parse unit test cases from test files
As of now, we need to sync three different places when adding new unit test cases. The plan is to add a python script in tools/unit-test-app. This script would parse unit test cases from the C files with tests and generate the needed YAML files in components/idf_test/unit_test. CI would run this script in build stage to create the files and unit-test stage would use the generated files to run tests.
To get the needed test metadata, we need to add some more tags in the test case functions. For example:
```
TEST_CASE("SYS_LIB_0102 test time functions", "[stdlib][fails][env=UT_T1_APC]")
{
//...
}
```
Reason for this kind of implementation is that we need the YAML files for generating documents.

spi_flash: fix race condition when doing operations in unpinned tasks
spi_flash_enable_interrupts_caches_and_other_cpu function used to enable
non-IRAM interrupts after giving up flash operation lock, which would
cause problems if another task was waiting on the lock to start a flash
operation. In fact, non-IRAM interrupts should be re-enabled before the
task scheduler is resumed. Otherwise non-pinned task can be moved to the
other CPU due to preemption, causing esp_intr_noniram_enable to be
called on the other CPU, causing an abort to be triggered.

time: workaround for FRC_TIMER_INT_REG write issue

Writing to another DPORT register immediately before or after that works around the issue.
We write one dummy value to an address which doesn’t have any register associated with it.

newlib: change definition of assert for release builds
One common pattern of using assert function looks as follows:
int ret = do_foo();
assert(ret == 0); // which reads as: “do_foo should never fail here, by design”
The problem with such code is that if ‘assert’ is removed by the preprocessor in release build,
variable ret is no longer used, and the compiler issues a warning about this.
Changing assert definition in the way done here make the variable used, from language syntax perspective.
Semantically, the variable is still unused at run time (as sizeof can be evaluated at compile time), so the compiler
can optimize things away if possible.
