nvs_flash_init may return an error code in some cases, and applications
should check this error code (or at least assert on it being ESP_OK, to
make potential issues more immediately obvious).
This change modifies all the examples which use NVS to check the error
code. Most examples get a simple ESP_ERROR_CHECK assert, while NVS
examples, OTA example, and NVS unit tests get a more verbose check which
may be used in real applications.
This change adds a check for the free page count to nvs_flash_init.
Under normal operation, NVS keeps at least one free page available,
except for transient states such as freeing up new page. Due to external
factors (such as NVS partition size reduction) this free page could be
lost, making NVS operation impossible. Previously this would cause an
error when performing any nvs_set operation or opening a new namespace.
With this change, an error is returned from nvs_flash_init to indicate
that NVS partition is in such a state.
Bugfix/mdns security issues
Fixes a series of security issues with MDNS.
STACK-SMASH: dd3f18d2d8/components/mdns/mdns.c (L494):
The sprintf is not limited. We can execute the sprintf codeflow as
many times as we want, allowing arbitrary long data being written
into stack.
PACKET-OF-DEATH:
dd3f18d2d8/components/mdns/mdns.c (L502).
The compare allows equal, and thus jumping back to it self infinite
recursion -> guaranteed crash
TXT-SMASH: dd3f18d2d8/components/mdns/mdns.c (L1381)
The loop does not check on reaching a->txt maximum size (1024),
resulting in stack overflow.

make: don’t override TEST_COMPONENTS
When idf_monitor is launched from make, it gets modified `TEST_COMPONENTS`
variable which contains full paths to the test components instead of the
names. This causes `TEST_COMPONENT_PATHS` to be empty and the unit test
app gets built without any test components.
This change introduces an internal `TEST_COMPONENTS_LIST` variable which
gets set either from `COMPONENTS` if `TESTS_ALL` is 1, or from
`TEST_COMOPONENTS` otherwise.
Bootloader makefile is also fixed to avoid propagating `TESTS_ALL` to the
bootloader build step.

bug fix: fix uart data bug when stop-bit is set as 2-bit mode
This is a workaround for a hardware bug.
When we want to use 2-stop-bit mode, we need to set stop-bit-1 and set dl1_en in rs485 register.
