f47d2ed5fe sys_arch_mbox_tryfetch not validated correctly 
sys_arch_mbox_tryfetch() shall return SYS_MBOX_EMPTY or 0 according
to the documentation. Wherever the function is used the return
value is incorrectly compared to SYS_ARCH_TIMEOUT. For now
SYS_MBOX_EMPTY is defined to SYS_ARCH_TIMEOUT so this is not an
issue as long as SYS_MBOX_EMPTY isn't re-defined.

eeb2218b3d Revert "Test / RFC: Reformat a few files using clang-format" 
This reverts commit 8b4a8159a898795ef0fc9226dae1ce66531ad487.

We do not want to do this shortly before a release. Reformatting (buggy reformatting) may introduce new bugs.

d9770d2c5f tcpip_thread: TCPIP_MSG_INPKT: free input pbufs if the input function returns an error 
This simply wasn't the case until 6LoWPAN. However, since tcpip_input is like this, we
should stay with that pattern.

Adapted documentation in netif.h

c257b56a39 move sys_timeouts_mbox_fetch() to tcpip_timeouts_mbox_fetch() 
This cleans up the code: sys_timeouts_mbox_fetch() was only used from
tcpip.c anyway, so let's move it there.

8fc20142f7 Added sys_mbox_trypost_fromisr() and tcpip_callbackmsg_trycallback_fromisr() 
This can be used to post preallocated messages from an ISR to the tcpip thread
when using FreeRTOS, where where calls differ between task level and ISR level.

d569a22c73 tcpip: ensure core is locked for init done function 
This ensures the core is locked when executing the init done function
passed to tcpip_init

The could manifest as a synchronization issue during early init if
another thread was in the LwIP context at the same time

10a5afeee7 Revert my last change to tcpip_callback() - it breaks the semantics of the function. 
The function previously returned after posting a message, which is a short operation. Now it actually waits until the operation has completed - which may take a long time. This may break user programs. So all that remains is the cleanup separation in tcpip_callback() and tcpip_try_callback() :-(

68d36f19f0 Implement LWIP core locking support in tcpip_callback_with_block() 
Created two new functions for API cleanup:
tcpip_callback() that blocks until message is posted, cannot be called from IRQs.
tcpip_try_callback() that does not block and just tries to post a message. Can be called from IRQs.
Add compatibility #define tcpip_callback_with_block() that maps to these two functions according to "block" parameter.
