dd6d34e7dc tests: net: second pass at cleanup tests to build on all platforms
The majority of these fixes adjust the memory limit needed to build the
various tests on systems with and without BLE support.  We also fixup
one test case that was able to run on platforms with 16k of memory.

c58be92208 samples: net: irc_bot: fix stack declarations
kernel APIs have changed to using K_THREAD_STACK_DEFINE to declare stack
memory as well as K_THREAD_STACK_SIZEOF to calculate it's size.

Adjust irc_bot sample to reflect those changes.

This fixes stack related page faults when running irc_bot with
CONFIG_X86_STACK_PROTECTION enabled (which it is by default for qemu).

ebc948d818 tests: net: limit tests to boards with enough memory to build them
A number of the network tests have minimal memory requirements that not
all boards are able to meet.  Add in those memory requirements so we
don't attempt to build these tests for those platforms.  Utilized the
frdm_kl25z (with 16K of memory) and cc2650_sensortag (with 20K) to test
the limits.

Since we generate BLUETOOTH_MONITOR_ON_DEV_NAME based on dts we need a
!HAS_DTS check around it.  Otherwise we can get into odd build errors.
Its also possibly that we don't specify "zephyr,bt-mon-uart" and in that
case we default to CONFIG_UART_CONSOLE_ON_DEV_NAME (ie 'zephyr,console'
on DTS platforms).

befb0695ba kernel.h: add note about K_THREAD_STACK_SIZEOF()
Each member of the array may need to have a padding size added
such that the base address of each array element corresponds to
the desired stack alignment.

This would mean that sizeof(some array element) would return
a larger size than what was originally provided.

This won't cause problems at runtime since the space is really
there, but for users who are only enabling this padding for
debug features, they may be surprised when their stacks are
effectively smaller than when this was enabled.

497f8fd40a build: export flashing and debugging info, when present
Zephyr supports the flash and debug targets via per-board information
in Makefile.board files.

It is sometimes convenient to know this information when inspecting
the build artifacts or doing exotic builds, so include it in the file
generated by outputexports. The information in Makefile.board provides
what is needed.

Therefore, ensure that Makefile.board, when present, is included by
the generated Makefile.export. This gives users of Makefile.export
access to variables like FLASH_SCRIPT, PYOCD_TARGET, etc. (These users
need to cope with these variables being undefined if not given in
Makefile.board, or if Makefile.board does not exist for a target.)

While we're here, don't export INSTALLKERNEL. That's Linux-specific
and otherwise unused; the Zephyr equivalent is FLASH_SCRIPT and its
associated variables.

45eac217a2 net: tests: Enable net tests for all suitable platforms
Instead of only running net tests in qemu_x86, enable those
tests in all suitable platforms. The tests are disabled for
bbc_microbit as that platform does not have enough memory.

The tests/net/arp and tests/net/ieee802154/l2 are disabled
for qemu_xtensa as the qemu crashed when running the tests.
For tests/net/all there was a weird build error for qemu_xtensa
so that test is also disabled for that platform.

Increased the trickle timeout to 3 secs in tests/net/trickle as
occacionally there was timeout error in qemu_cortex_m3 when the
test was run.
