f1b6e6bb15 unix/modos: Implement putenv and unsetenv to complement getenv.
CPython also has os.environ, which should be used instead of os.getenv()
due to caching in the os.environ mapping.  But for MicroPython it makes
sense to only implement the basic underlying methods, ie getenv/putenv/
unsetenv.

660a61a388 extmod/vfs_lfs: Allow compiling in VfsLfs1 and VfsLfs2 separately.
These classes are enabled via the config options MICROPY_VFS_LFS1 and
MICROPY_VFS_LFS2, which are disabled by default.

fadd6bbe43 unix/moduos_vfs: Add missing uos functions from traditional uos module.
Now that the coverage build has fully switched to the VFS sub-system these
functions were no longer available, so add them to the uos_vfs module.

Also, vfs_open is no longer needed, it's available as the built-in open.

1d40f12e44 unix: Support MICROPY_VFS_POSIX and enable it in coverage build.
The unix coverage build is now switched fully to the VFS implementation, ie
the uos module is the uos_vfs module.  For example, one can now sandbox uPy
to their home directory via:

    $ ./micropython_coverage

    >>> import uos
    >>> uos.umount('/') # unmount existing root VFS
    >>> vfs = uos.VfsPosix('/home/user') # create new POSIX VFS
    >>> uos.mount(vfs, '/') # mount new POSIX VFS at root

Some filesystem/OS features may no longer work with the coverage build due
to this change, and these need to be gradually fixed.

The standard unix port remains unchanged, it still uses the traditional uos
module which directly accesses the underlying host filesystem.

01dd7804b8 ports: Make new ports/ sub-directory and move all ports there.
This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
