Printing too large of a string can fail in Windows, as detailed here:
https://bugs.python.org/issue11395. This works around the problem by
adding a print_large_string function that breaks up the string into
smaller pieces before printing it.
Replace Comodo and OpenDNS IPv4 servers with Google and DNS.WATCH IPv6
servers, so IPv6-only devices (eg 6LoWPAN) have a default.
3 IPv4 resolvers should be plenty - existing code doesn't remember which
one last worked, so if early list entries were unreachable performance
would be consistently bad anyway. Replacing two entries avoids
increasing image size and RAM consumption.
On an IPv6-only or IPv4-only system, the sendto() for the wrong type of
address should fail immediately - change loop to move on to the next
server for any sendto() error.
Before, mbed_app.json files were explicitly ignored when building tests.
This was mostly because you could have multiple mbed_app.json files in the
tree (for instance, in test case folders) and the behavior would be
undefined. Now the tools explicitly ensure that there aren't multiple
mbed_app.json files in your source files. So auto discovery of
mbed_app.json for testing is being reintroduced.
Takes advantage of the get_ip_address function to predict the IP
address version wanted by the underlying interface. The should avoid
the need for most IPv6 interfaces to overload gethostbyname.

Adding the new compile option allows the marking of a set of examples to
indicate whether they should be compiled or not. For the update process
examples that are not compiled will not be auto updated irrespective of
that setting.
Other changes to make return logic from some functions in update.py more
efficient and some typos in the lib file.
Changes:
Refactor examples.py to add a new command line option to provide an update
tag.
Refactor examples.py to add new functionality to update the version of
mbed-os in the examples to a supplied tag.
Refactor examples.py to make cloning the example repos, updating their
mbed-os version and compiling, into library functions and move to a new
library module.
Refactor the format of the examples.json file to make it compatible with
both examples.py and update.py.
Refactor update.py so that examples are test compiled prior to updating.
Refactor update.py so that only examples tagged as auto-updatable and that
fully compile are automatically updated.
Previously, exhausting hardware buffers would begin blocking the lwip
thread. This patch changes the emac layer to simply drop ethernet
frames, leaving recovery up to a higher level protocol.
This is consistent with the behaviour of the emac layer when unable
to allocate dynamic memory.
This was actually several bugs colluding together.
1. Confusion on the buffer-semaphore paradigm used led to misuse of the
tx semaphore and potential for odd behaviour.
2. Equality tests on tx_consume_index and tx_produce_index did not
handle overflow correctly. This would allow tx_consume_index to catch
up to tx_produce_index and trick the k64f_rx_reclaim function into
forgetting about a whole buffer of pbufs.
3. On top of all of that, the ENET_BUFFDESCRIPTOR_TX_READ_MASK was not
correctly read immediately after being set due to either a compiler
optimization or hardware delays. This caused k64f_low_level_output
to eagerly overrun existing buff-descriptors before they had been
completely sent. Adopting the counting-semaphore paradigm for 1 avoided
this concern.
As pointed out by @infinnovation, the overflow only occurs in the rare
case that the 120MHz CPU can actually generate packets faster than the
ENET hardware can transmit on a 100Mbps link.
This test was causing issues on some platforms because the serial output
would get garbled and cause exceptions to occur in the testing tools. This
corrects the behavior to follow the other tests. It will now defer all
pritning until after the __sync event occurs.
This change prevents the standard library from allocating a large buffer
on the heap. On GCC_ARM, this is a saving of 1K. On ARM, this is a saving
of 64 bytes.
