One can instead lookup __name__ in the modules dict to get the value.

Adds horizontal scrolling. Right now, I'm just leaving the margins
created by the scrolling as they were -- so they will repeat the
edge of the framebuf. This is fast, and the user can always fill
the margins themselves.

So that users of framebuf don't need to have stmhal directory in their
path.  (Eventually the font can be moved elsewhere.)

There was a bug in `framebuf1_fill` function, that makes it leave a few
lines unfilled at the bottom if the height is not divisible by 8.

A similar bug is fixed in the scroll method.

The idea is that all ports can use these helper methods and only need to
provide initialisation of the SPI bus, as well as a single transfer
function.  The coding pattern follows the stream protocol and helper
methods.

This is an object-oriented approach, where uos is only a proxy for the
methods on the vfs object.  Some internals had to be exposed (the STATIC
keyword removed) for this to work.

Fixes #2338.

Disable by default, enable in unix port.

In `btree_seq()`, when `__bt_seq()` gets called with invalid
`flags` argument it will return `RET_ERROR` and it won't
initialize `val`. If field `data` of uninitialized `val`
is passed to `mp_obj_new_bytes()` it causes a segfault.

Consistently use stdint types. Fixes stmhal build.

Fixes for pedantic compiler warnings.

New API supporting stream decompression.

This goes bit against websocket nature (message-based communication),
as it ignores boundaries bertween messages, but may be very practical
to do simple things with websockets.

Namely: flags, cachesize, pagesize, minkeypage.

In the sense that while GET_FILE transfers its data, REPL still works.
This is done by requiring client to send 1-byte block before WebREPL
server transfers next block of data.

Requires "embedded" BerkeleyDB BTree implementation.

Previoussly such read() and write() methods were used by modussl_axtls,
move to py/stream for reuse.

Shares the code with remove() method due to the same underlying f_unlink()
FatFs operation.

Accepts only value of True.

Make variable MICROPY_SSL_AXTLS=1 should be defined to activate modussl_axtls
and link with -laxtls.

Instead of allocating new array object header again and again, causing
memory fragmentation.

Allocating it for each read/write operation is a memory fragmentation
hazard.
