Jeff Epler fe3e8d1589 string compression: save a few bits per string
Length was stored as a 16-bit number always.  Most translations have
a max length far less.  For example, US English translation lengths
always fit in just 8 bits.  probably all languages fit in 9 bits.

This also has the side effect of reducing the alignment of
compressed_string_t from 2 bytes to 1.

testing performed: ran in german and english on pyruler, printed messages
looked right.

Firmware size, en_US
Before: 3044 bytes free in flash
After: 3408 bytes free in flash

Firmware size, de_DE (with #2967 merged to restore translations)
Before: 1236 bytes free in flash
After: 1600 bytes free in flash

Noralf Trønnes c5aa2e9300 Support OSError attributes
This adds support for the OSError attributes : errno, strerror, filename and filename2.
CPython only sets errno if 2 arguments has been passed in. This has not been implemented here.

CPython OSError.args is capped at 2 items for backward compatibility reasons. This has not been
implemented here.

MICROPY_CPYTHON_COMPAT has to be enabled to get these attributes.

mp_common_errno_to_str() has been extended to check mp_errno_to_str() as well. This is done to ease
reuse for the strerror argument.

Compress all translated strings with Huffman coding.
This saves code space in builds which use link-time optimization.
The optimization drops the untranslated strings and replaces them
with a compressed_string_t struct. It can then be decompressed to
a c string.

Builds without LTO work as well but include both untranslated
strings and compressed strings.

This work could be expanded to include QSTRs and loaded strings if
a compress method is added to C. Its tracked in #531.

Two fixes and translate more strings.
* Fix finding translations with escaped characters.
* Add back \r to translations since its needed by screen.

Matt Wozniski 1c35dbfb5d Provide mp_errno_to_str even without uerrno
We can provide a basic version of mp_errno_to_str even if the uerrno
module won't be provided.  Rather than looking errno names up in the
uerrno module's globals dict, we'll just rely on a simple mapping in the
function itself.

Damien George b1b090255c py/moduerrno: Make list of errno codes configurable.
It's configurable by defining MICROPY_PY_UERRNO_LIST.  If this is not
defined then a default is provided.

Damien George 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.

Damien George 93c4a6a3f7 all: Remove 'name' member from mp_obj_module_t struct.
One can instead lookup __name__ in the modules dict to get the value.

Useful to check file/dir operations result, in particular used by upip.

Damien George 9a92499641 py/objexcept: Don't convert errno to str in constructor, do it in print.
OSError's are now printed like:

    OSError: [Errno 1] EPERM

but only if the string corresponding to the errno is found.

Damien George d45e5f8c35 py: Add mp_errno_to_str() and use it to provide nicer OSError msgs.
If an OSError is raised with an integer argument, and that integer
corresponds to an errno, then the string for the errno is used as the
argument to the exception, instead of the integer.  Only works if
the uerrno module is enabled.
