libc and libnx: When the libraries are built into two libraries, a user space library and a OS space library (as in the PROTECTED and KERNEL build). Then the user space library must not use the OS internal interfaces; similarly, the OS must avoid using the userspace interfaces so that it does not muck the errno value or create spurious cancellation points.

drivers/serial/tcdrain: tcdrain() was recently added to the NuttX C library. But there is a problem. The specification of tcdrain() requires that it be a cancellation point. In order to do this, tcdrain was moved from the C library into the OS and the addition cancellation point hooks were added. In non-FLAT builds, access via system calls is also now supported.

Adds new OS internal functions nxsig_sleep() and nxsig_usleep. These differ from the standard sleep() and usleep() in that (1) they don't cause cancellation points, and (2) don't set the errno variable (if applicable). All calls to sleep() and usleep() changed to calls to nxsig_sleep() and nxsig_usleep().

Change all calls to usleep() in the OS proper to calls to nxsig_usleep()
sched/signal: Add a new OS internal function nxsig_usleep() that is functionally equivalent to usleep() but does not cause a cancellaption point and does not modify the errno variable.
sched/signal: Add a new OS internal function nxsig_sleep() that is functionally equivalent to sleep() but does not cause a cancellaption point.

This change renames all internal, private NuttX signal-related functions to use the prefix nxsig_ so that they cannot be confused with application interfaces that begin, primarily, with sig_

Addes support for read-only routing tables. Prior to this change, routing tables were only support in RAM and had to be initialized with explicit logic to add the necessary routes to the routing table. With this change, routes may be defined in the pre-initialized, read-only routing table provided by the board-specific logic
...
This would be particularly useful, for example, in the case where there is only a single network adaptor and you want all output packets to go to the single adaptor in all cases. So for that behavior you could add a read-only routing table to the board-specific long that contains a single entry, the default route: 0.0.0.0/0.
Squashed commit of the following:
net/route: RAM and ROM routing tables build correctly in all IPv4 and IPv6 configurations.
net/route: Verify IPv6 ROM route build; Make number of ROM routes a variable, not a configuration item.
net/route: Add initial support for ROM-base, read-only routing tables.
net/route: Adjust and generalize some structures, rename some functions, and add configuration and build support that will eventually support read-only routing tables.
net/route: Some initial though experiments on use of a fixe, read-only routing table

We discovered a problem with the samv7 mcan driver which results, under some circumstances, in a very high CPU load.
The problem occurs, and is easily reproducible, if the device is connected to a CAN network with a wrongly configured CAN speed (baud rate). In our tests we set the CAN speed of the device to 1000000 and the speed of the other CAN nodes to 500000. The device is restarted and sends a CANopen “bootup message” to the CAN network. This results in huge amount of errors messages on the CAN bus, probably because of the CAN feature for acknowledging error messages. The error messages can’t be read by the device because of the misconfigured CAN speed, instead the CAN chip reports lots of errors, which are reported to the application which uses the CAN driver (CONFIG_CAN_ERRORS is enabled).
The CAN errors are reported from the CAN chip via interrupts and thus the interrupt load is very high in this scenario. To fix the problem the driver now disables each RX error interrupt after it is occurred. The RX error interrupts are turned back on if at least one CAN message is received successfully.

libc/stdlib: Error Fix
...
1.Fix an error in mkstemp() the could result in an infinite loop.
2.Fix for wrong output in some cases.
For Example:
1) input: "FILEXX"
output: "FILE00" and repeats same output for further invocations of mkstemp().
But, the ouput has to be FILE01, FILE02, ...., FILEZZ.
2)input: "FILEXXXXXX"
output: "FILE100000", for next invocation "FILE200000" and so on
But it's good, if the ouput goes like FILE000001, FILE000002, ..., FILE000101, ...

Whoops -- that #include <cxxabi.h> wasn't supposed to sneak in there. If present, it may already define a __cxxabiv1::__guard that we could use, but that file comes from libstdc++, and I don't think the NuttX buildroot-based toolchain would have that, which is why we need libxx in the first place.
