If GeneratorExit is injected as a throw-value then that should lead to
the close() method being called, if it exists. If close() does not exist
then throw() should not be called, and this patch fixes this.
CPython 3.6 has a few changes that, when run on uPy's test suite, give a
different output to CPython 3.5. uPy currently officially supports the
3.4 language definition, but it's useful to be able to run the test suite
with 3.4/3.5/3.6 versions of CPython. This patch makes such changes to
support 3.6.
The commit d9047d3c8a introduced a bug
whereby "from a.b import c" stopped working for frozen packages. This is
because the path was not properly truncated and became "a//b". Such a
path resolves correctly for a "real" filesystem, but not for a search in
the list of frozen modules.
This effectively reverts the change that introduced this new constant.
The reason is so that users do not need to rebuild the filesystem on
their modules when upgrading the firmware.
Users can change RESERVED_SECS by hand if they need the feature, and in
future firmware it may default to a non-zero value.
This code is no longer pertinent for some time - since switchover to
SDK2.0, there must be correct flash size set for bootloader, or there's
a risk of flash data corruption. And indeed, the correct flash size is
by default auto-detected by esptool.py 1.2.
