The generated regex code is limited in the range of jumps and counts, and
this commit checks all cases which can overflow given the right kind of
input regex, and returns an error in such a case.
This change assumes that the results that overflow an int8_t do not
overflow a platform int.

CPython does not have an implementation of select.poll() on some
operating systems (Windows, OSX depending on version) so skip the
test in those cases instead of failing it.
This test doesn't check the actual I/O behavior, just "static" invariants
like behavior on duplicate calls or calls when I/O object is not registered
with poller.
Commit 95e70cd0ea 'time: Use 1970 epoch' changed epoch for the time
module, but not for other users. This patch does the same for the only
other core timeutils user: extmod/vfs_fat.c:fat_vfs_stat().
Other timeutils users: cc3200, esp8266 and stm32, are not changed.
Ports that don't use long ints, will still get wrong time values from
os.stat().

This conditional import was only used to get the tests working on the unix
coverage build, which has now switched to use VFS by default so the uos
module alone has the required functionality.
These allow accessing the filesystem label. For instance,
in boot.py, you can set the label on the built-in storage with:
storage.remount('/', False)
storage.getmount('/').label = "NEWLABEL"
storage.remount('/', True)
Users with multiple CIRCUITPY boards may find it desirable to
choose a different label for each board they own.
CPython doesn't allow SEEK_CUR with non-zero offset for files in text mode,
and uPy inherited this behaviour for both text and binary files. It makes
sense to provide full support for SEEK_CUR of binary-mode files in uPy, and
to do this in a minimal way means also allowing to use SEEK_CUR with
non-zero offsets on text-mode files. That seems to be a fair compromise.
This is just to test that the function exists and returns some kind of
valid value. Although this file is for testing ms/us functions, put the
ticks_cpu() test here so not to add a new test file.
