[PATCH] Deprecate sys_arch_sem_wait and sys_arch_mbox_fetch returning the time waited
...
These are now defined to return != SYS_ARCH_TIMEOUT on success rather than the time
waiting. The returned times were unused by lwip and this simplifies at
least some implementations.

Clarify that sys_arch_protect() always has a matching unprotect.
...
This is to allow an implementation to use a nesting counter, or a
recursive mutex. Also clarify that the value returned by
sys_arch_protect() is opaque to lwip and implementation dependent.

sys_arch.txt, api.h, api_lib.c, api_msg.h, api_msg.c, tcpip.c, sys.h, opt.h: Introduce changes for task #7490 "Add return value to sys_mbox_post" with some modifications in the sys_mbox api: sys_mbox_new take a "size" parameters which indicate the number of pointers query by the mailbox. There is three defines in opt.h to indicate sizes for tcpip::mbox, netconn::recvmbox, and for the netconn::acceptmbox. Port maintainers, you can decide to just add this new parameter in your implementation, but to ignore it to keep the previous behavior. The new sys_mbox_trypost function return a value to know if the mailbox is full or if the message is posted. Take a look to sys_arch.txt for more details. This new function is used in tcpip_input (so, can be called in an interrupt context since the function is not blocking), and in recv_udp and recv_raw.

Change parameters list for sys_thread_new (see "task #7252 : Create sys_thread_new_ex()"). Two new parameters have to be provided: a task name, and a task stack size. For this one, since it's platform dependant, you could define the best one for you in your lwipopts.h. For port maintainers, you can just add these new parameters in your sys_arch.c file, and but it's not mandatory, use them in your OS specific functions.

(Earlier, the 14-byte ethernet header screwed this up, this had already been fixed by adding two pad bytes.)
Assumption is that compilers do not align with larger-than-sizeof(type) boundaries.
