Pullreq libc libnx updates
* NuttX: make strerror() return 'Success' for 0
* NuttX: fix strrchr() so that it considers null terminator as part of string
From strrchr(3) man page:
"The terminating null byte is considered part of the string, so that if c
is specified as '\0', these functions return a pointer to the terminator."
* NuttX: mm_free(): Add DEBUGASSERT()'s to catch memory corruption early.
It's easier to find the source when asserts fail already when freeing
an overflowed buffer, than if the corruption is only detected on next
malloc().
* MM_FILL_ALLOCATIONS: Add debug option to fill all mallocs()
This is helpful for detecting uninitialized variables,
especially in C++ code. I seem to be forgetting to initialize
member variables and then they just get random values..
* NuttX: nxtk_bitmapwindow: Fix warning message when bitmap is fully off-screen.
* nxfonts_getfont: Avoid unnecessary warnings for other whitespace chars also.
* NuttX: Fix kerning of 'I' in Sans17x22 font
The I character was running together with some other
characters, e.g. in sequence "IMI".
* NXMU: Revalidate window pointer for mouse events.
NXMU caches the previous window pointer so that further mouse
events can be sent to the same window. However, if the window
is destroyed while mouse button is held down, the pointer may
become invalid and cause a crash. This patch revalidates the
pointer before using it.

The MLD implementation did not follow the RFC correctly when it is the Querier. The Querier should use a general query and get query messages from all members of all groups. This would be driven by a single timer per sub-nset since all groups are queried at once. Instead, the design used a Multicast Address Specific Query with one timer per group and ignores groups that we are not members of.
Similary, the MLDv1 compatibility timer should be a single, separate timer, not a per-group timer.
net/mld: Group may be NULL when sending a general query
net/icmpv6/icmpv6_input.c: Correct caculation of the ICMPv6 header address
net/mld/mld_query.c: Correct back test for group found.
net/mld/mld_report.c: Fix host vs. network order problem.
net/mld/mld_send.c: Correct the address used in sending the General Query. It should be the unspecified address in that case.
net/mld: Querying workaround. The MLD implementation does not follow the RFC correct when it is the Querier. The Querier should use a general query and get query messages from all members of all groups. This would be driven by a single timer since all groups are queried at once. Instead, the design currently uses a Multicast Address Specific Query with one timer per group and ignores groups that we are not members of.
1. open CONFIG_DEBUG_FEATURES CONFIG_SYSTEM_TIME64 CONFIG_CLOCK_MONOTONIC
==> INITIAL_SYSTEM_TIMER_TICKS very big data, not zero
2. close CONFIG_SCHED_TICKLESS
==> use g_system_timer as system clock
3. pm_domain_s.stime init to zero
4. clock_systimer() - pm_domain_s.stime get big data, error
Normally it is required that the network be in the "down" state when re-configuring the network interface. This is thought not to be a necessary here because.
1. The ICMPv6 logic here runs with the network locked so there can be no outgoing packets with bad source IP addresses from any asynchronous network activity using the device being reconfigured.
2. Incoming packets depend only upon the MAC filtering. Network drivers do not use the IP address; they filter incoming packets using only the MAC address which is not being changed here.
