pkg: wakaama: Fix and update wakaama package to version fe48d45

[moenoel]

This pull request updates the Eclipse wakaama package to a more current version from the main repository.

I've tested this change by compiling examples/hello-world/ with USEPKG += wakaama for several BOARDs (native, bluepill, stm32f4discovery, ...), since there is no actual test for this package. I also only tested whether it would compile but no functionality (yet).

This does not compile when size_t <= 16 bit , like with BOARD=arduino-uno, but that shouldn't work with the current version either (if that ever worked, since there's an error in the makefile and the patches don't apply for me).

In the future I would like add an example application for this and/or a module that could provide default objects for LwM2M and bindings for supported hardware.

There also is this related issue #8106
I will look at both.

If I understand what you did (trying to read diff between two patch files is tricky):

• Fix the not updated PKG_TEMP_DIR to PKG_BUILDDIR
• Bump the version
• Make the patches apply and fix warnings/errors

When rebased on the last master with -Wall -Wextra -Werror I have no error when building.
It may not work, but its better than not building.

If you could change the commit message, to prepend the directory, like the older commit in this directory: pkg: wakaama: Fix and update wakaama package to version XYZ and in the body the steps of the update (== my description or your corrected one) it would be perfect.

I will ACK after rewording the commit message.

@florian-jean: can you check this too ? It could be used as a base commit for your added functionalities

@cladmi

Yes I would gladly use this as base commit.
In fact I already bump in the lattest version of wakkama and modified all the core and examples files in order to compile the without the WERROR=0 in the repo I updated in #8106 but a few files still need to be fixed

[cladmi]

For maintainers: can be tested with

USEPKG+=wakaama make -C examples/hello-world
USEPKG+=wakaama make -C examples/hello-world BOARD=samr21-xpro

@cladmi I did just that and added a few more fixes while I was at it.

I forgot to test compilation with the different operation modes. I've tested the new changes as follows:

Client with bootstrap mode:
USEPKG+=wakaama CFLAGS+="-DLWM2M_CLIENT_MODE -DLWM2M_BOOTSTRAP" make -C examples/hello-world

Client without bootstrap mode:
USEPKG+=wakaama CFLAGS+=-DLWM2M_CLIENT_MODE make -C examples/hello-world

Server mode:
USEPKG+=wakaama CFLAGS+=-DLWM2M_SERVER_MODE make -C examples/hello-world

Bootstrap-server mode:
USEPKG+=wakaama CFLAGS+=-DLWM2M_BOOTSTRAP_SERVER_MODE make -C examples/hello-world

[cladmi]

Not compiling package now compiles, ACK.

Did not tested the functionality but its an improvement anyway.
