Prior to this fix, the final piece of data in a compressed file may have
been lost when decompressing.

This library is a small and easy-to-use cryptographic library which is well
suited to embedded systems.

The original logic of reducing a full path to a relative one assumes
"tests/misc" is in the filename which is limited in usage: it never works
for CPython on Windows since that will use a backslash as path separator,
and also won't work when the filename is a path not relative to the tests
directory which happens for example in the common case of running
"./run-tests -d misc".
Fix all cases by printing only the bare filename, which requires them all
to start with sys_settrace_ hence the renaming.
Changes are:
- Remove include of stm32's adc.h because it was recently changed and is
no longer compatible with teensy (and not used anyway).
- Remove define of __disable_irq in mpconfigport.h because it was clashing
with an equivalent definition in core/mk20dx128.h.
- Add -Werror to CFLAGS, and change -std=gnu99 to -std=c99.

Mboot builds do not use the external SPI flash in caching mode, and
explicitly disabling it saves RAM and a small bit of flash.

This only needs to be enabled if a board uses FAT FS on external SPI flash.
When disabled (and using external SPI flash) 4k of RAM can be saved.

When littlefs is enabled extended reading must be supported, and using this
function to read the first block for auto-detection is more efficient (a
smaller read) and does not require a cached SPI-flash read.

These functions enable SDRAM data retention in stop mode. Example usage,
in mpconfigboard.h:
#define MICROPY_BOARD_ENTER_STOP sdram_enter_low_power();
#define MICROPY_BOARD_LEAVE_STOP sdram_leave_low_power();
Calculate the bit timing from baudrate if provided, allowing sample point
override. This makes it a lot easier to make CAN work between different
MCUs with different clocks, prescalers etc.
Tested on F4, F7 and H7 Y/V variants.
This commit prevents uos.mount() from raising an AttributeError.
vfs_autodetect() is supposed to return an object that has a "mount" method,
so if no filesystem is found it should raise an OSError(ENODEV) and not
return the bdev itself which has no "mount" method.
Mounting a bdev directly tries to auto-detect the filesystem and if none is
found an OSError(19,) should be raised.
The fourth parameter of readblocks() and writeblocks() must be optional to
support ports with MICROPY_VFS_FAT=1. Otherwise mounting a bdev may fail
because looking for a FATFS will call readblocks() with only 3 parameters.
Since CPython 3.8 the optional "sep" argument to hexlify is officially
supported, so update comments in the code and the docs to reflect this.

As a general pattern, required positional arguments that are not named do
not need to be parsed using mp_arg_parse_all().

This much buffer space is required for CDC data out endpoints to avoid any
buffer overflows when the USB CDC is saturated with data.
