Fixes bug #48300 (Private mempools allocate foreign memory), bug #48354 (Portable alignment defines/include required for static allocation) and bug #47092 (Tag memory buffers like memp_memory_xxx and ram_heap with a macro so that attributes can be attached to their definitions)

If lwIP encounters a half-open connection (e.g. due to a restarted
application reusing the same port numbers) it will correctly send a
RST but will not resend the SYN until one retransmission timeout later
(approximately three seconds). This can increase the time taken by
lpxelinux.0 to fetch its configuration file from a few milliseconds to
around 30 seconds.
Fix by immediately retransmitting the SYN whenever a half-open
connection is detected.

Notify phase callback, enabled using the PPP_NOTIFY_PHASE config option,
let user configure a callback that is called on each PPP internal state
change. This documents how to use it.
I think that "#define SZT_F PRIuPTR" has a much better chance
of being right, making the assumption that uintptr_t is the same as
size_t.
Dirk: I think Ambroz is right.
lwip/src/core/init.c:256:32: error: "LWIP_COMPAT_MUTEX" is not defined [-Werror=undef]
#if LWIP_TCPIP_CORE_LOCKING && LWIP_COMPAT_MUTEX && !defined(LWIP_COMPAT_MUTEX_ALLOWED)
^
Setting LWIP_TCPIP_CORE_LOCKING is meaningless for NO_SYS targets,
therefore checking if LWIP_COMPAT_MUTEX is set does not make sense.
Introduced by 42dfa71f97: Make LWIP_TCPIP_CORE_LOCKING==1 the default
(and warn if LWIP_COMPAT_MUTEX==1 in that case as mutexes are required
to prevent priority inversion on tcpip_thread operations)
PPP is just the upper protocol for PPPoE and PPPoL2TP, meaning it is only
started once "E" or L2TP is established. Therefore waiting indefinitely
for LCP packets on the PPP side does not make sense at all, if the lower
level protocol is UP, PPP *MUST* comes up as well or we should restart from
the beginning.
There is two passive modes for PPPoS, passive more, for which we will
try to connect and then listen silently, and silent mode, for which we
will listen silently from the beginning.
Introduce ppp_set_passive and ppp_set_silent so the mode can be chosen
before connecting/listening.
All modules using PolarSSL embedded library are now using pppcrypt.h.
This header use to be only necessary for MSCHAP and was not built if
MSCHAP wasn't enabled, we unfortunately left the build condition.
Introduced by 3417a02b25: PPP: add a function map for hashes and ciphers
to prepare for mbed TLS support.
Setting PPP authentication most only be done when the PPP PCB is in the
dead phase (i.e. disconnected). This is safe to access the PPP PCB
members while the session is down, therefore providing a thread-safe
function of it is meaningless and it might even be misleading.
All our new ppp_set_* functions do not have their equivalent
pppapi_set_* functions and they are not going to have them. At least
we make ppp_set_auth consistent with all others ppp_set_*, so that it
doesn't look like special.
Helper function to setup MPPE (Microsoft Point to Point Encryption) for
a PPP link. Allows enabling/disabled MPPE itself, enabling/disabling
stateless support, and whether we are willing to negotiate 40-bit
and/or 128-bit encryptions.
print_string() displays characters as \\%.03o but without first
casting it from "char" to "unsigned char" so it gets sign-extended
to an int. This causes output like \37777777630 instead of \230.

Introduced by c0e7d54e37 "Removed 2 mem_mallocs: error string can be a
global variable, include memory for sc_ac_cookie in struct pppoe_softc;
commented out unused code (sc_service_name/sc_concentrator_name)".
Fixes it by bailing out if received AC cookie is to big for us, this
can't really happen anyway.
There is absolutely no reason I did it this way in the first
place, maybe I feared that not all compilers have a proper
implementation of offsetof() ? It sounds stupid.
Ports now only need to define datatypes and format strings on compilers that do not provide these two headers. Known good: GCC, IAR. Known bad: MSVC 2010.
Unfortunately, there is no standard way to declare a pointer with
potentially unaligned accesses. The only portable way is to create
packed struct.
VJ support uses optimized accesses to IP and TCP struct to check a
whole part of them at once to speed up the (de)compressor.
This commit wrap potentially unaligned *u16_t and *u32_t accesses with
packed struct so all compilers are able to deal with them properly.
Closes: #48308
