f5ee4d95a9 cc3200/moduos: Remove uos.sep, as it's strictly optional.
In MicroPython, the path separator is guaranteed to be "/", extra unneeded
things take precious code space (in the port which doesn't have basic things
like floating-port support).

f615d82d5b py/parse: Simplify handling of errors by raising them directly.
The parser was originally written to work without raising any exceptions
and instead return an error value to the caller.  But it's now required
that a call to the parser be wrapped in an nlr handler, so we may as well
make use of that fact and simplify the parser so that it doesn't need to
keep track of any memory errors that it had.  The parser anyway explicitly
raises an exception at the end if there was an error.

This patch simplifies the parser by letting the underlying memory
allocation functions raise an exception if they fail to allocate any
memory.  And if there is an error parsing the "<id> = const(<val>)" pattern
then that also raises an exception right away instead of trying to recover
gracefully and then raise.

5255255fb9 py: Create str/bytes objects in the parser, not the compiler.
Previous to this patch any non-interned str/bytes objects would create a
special parse node that held a copy of the str/bytes data.  Then in the
compiler this data would be turned into a str/bytes object.  This actually
lead to 2 copies of the data, one in the parse node and one in the object.
The parse node's copy of the data would be freed at the end of the compile
stage but nevertheless it meant that the peak memory usage of the
parse/compile stage was higher than it needed to be (by an amount equal to
the number of bytes in all the non-interned str/bytes objects).

This patch changes the behaviour so that str/bytes objects are created
directly in the parser and the object stored in a const-object parse node
(which already exists for bignum, float and complex const objects).  This
reduces peak RAM usage of the parse/compile stage, simplifies the parser
and compiler, and reduces code size by about 170 bytes on Thumb2 archs,
and by about 300 bytes on Xtensa archs.

74f4d2c659 py/parse: Allow parser/compiler consts to be bignums.
This patch allows uPy consts to be bignums, eg:

    X = const(1 << 100)

The infrastructure for consts to be a bignum (rather than restricted to
small integers) has been in place for a while, ever since constant folding
was upgraded to allow bignums.  It just required a small change (in this
patch) to enable it.

047af9b10b cc3200: Remove socket.timeout class, use OSError(ETIMEDOUT) instead.
socket.timeout is a subclass of OSError, and using the latter is more
efficient than having a dedicated class.  The argument of OSError is
ETIMEDOUT so the error can be distinguished from other kinds of
OSErrors.  This follows how the esp8266 port does it.

e859ddf3e1 cc3200: Enable uerrno module with short, custom list of error codes.
Since we recently replaced the OSError string messages with simple error
codes, having the uerrno module gets back some user friendly error
messages.  The total code size (after removing strings, replacing with
uerrno module) is decreased.

f563406d2e py/moduerrno: Make uerrno.errorcode dict configurable.
It's configured by MICROPY_PY_UERRNO_ERRORCODE and enabled by default
(since that's the behaviour before this patch).

Without this dict the lookup of errno codes to strings must use the
uerrno module itself.

29551ba566 cc3200: Move stoupper to ftp.c and define in terms of unichar_toupper.
ftp.c is the only user of this function so making it static in that file
allows it to be inlined.  Also, reusing unichar_toupper means we no longer
depend on the C stdlib for toupper, saving about 300 bytes of code space.

b7fa63c7ce tools: Add gen-cpydiff.py to generate docs differences.
This patch introduces the a small framework to track differences between
uPy and CPython.  The framework consists of:

- A set of "tests" which test for an individual feature that differs between
  uPy and CPy.  Each test is like a normal uPy test in the test suite, but
  has a special comment at the start with some meta-data: a category (eg
  syntax, core language), a human-readable description of the difference, a
  cause, and a workaround.  Following the meta-data there is a short code
  snippet which demonstrates the difference.  See tests/cpydiff directory
  for the initial set of tests.

- A program (this patch) which runs all the tests (on uPy and CPy) and
  generates nicely-formated .rst documenting the differences.

- Integration into the docs build so that everything is automatic, and the
  differences appear in a way that is easy for users to read/reference (see
  latter commits).

The idea with using this new framework is:

- When a new difference is found it's easy to write a short test for it,
  along with a description, and add it to the existing ones.  It's also easy
  for contributors to submit tests for differences they find.

- When something is no longer different the tool will give an error and
  difference can be removed (or promoted to a proper feature test).

86c7507233 tests/cpydiff: Add initial set of tests for uPy-CPython differences.
These tests are intended to fail, as they provide a programatic record of
differences between uPy and CPython.  They also contain a special comment
at the start of the file which has meta-data describing the difference,
including known causes and known workarounds.

534b7c368d py: Do adjacent str/bytes literal concatenation in lexer, not compiler.
It's much more efficient in RAM and code size to do implicit literal string
concatenation in the lexer, as opposed to the compiler.

RAM usage is reduced because the concatenation can be done right away in the
tokeniser by just accumulating the string/bytes literals into the lexer's
vstr.  Prior to this patch adjacent strings/bytes would create a parse tree
(one node per string/bytes) and then in the compiler a whole new chunk of
memory was allocated to store the concatenated string, which used more than
double the memory compared to just accumulating in the lexer.

This patch also significantly reduces code size:

bare-arm: -204
minimal:  -204
unix x64: -328
stmhal:   -208
esp8266:  -284
cc3200:   -224

773278ec30 py/lexer: Simplify handling of line-continuation error.
Previous to this patch there was an explicit check for errors with line
continuation (where backslash was not immediately followed by a newline).

But this check is not necessary: if there is an error then the remaining
logic of the tokeniser will reject the backslash and correctly produce a
syntax error.

ae43679792 py/lexer: Use strcmp to make keyword searching more efficient.
Since the table of keywords is sorted, we can use strcmp to do the search
and stop part way through the search if the comparison is less-than.

Because all tokens that are names are subject to this search, this
optimisation will improve the overall speed of the lexer when processing
a script.

The change also decreases code size by a little bit because we now use
strcmp instead of the custom str_strn_equal function.

a68c754688 py/lexer: Move check for keyword to name-tokenising block.

MP_TOKEN_NAME.
