The modern spiffs backend doesn't like stat("./somefile") for something
on the root of the filesystem, and instead only accepts "somefile"
(it also doesn't like "/somefile"). The error from stat was being
ignored which is why the file sizes all appeared to be zero.
The fix is to change file.list() to pass just the filename, unless a
directory was passed to list(). Also improved error handling a bit.
Slightly reworked embed_lfs.sh to better cope with attribute size changes
in future compiler versions, without needing to be updated again.
RMT register naming changed once again...
If this variable is not set in the config it may contain random data and set the clock source to the REF_CLK
resulting in timing errors, the DHTx, DS18B20 and ws2812 devices to not communicate.
The return value from fwrite was being checked against the size of the data rather than the number of bytes written.
This caused node.compile() to falsely return failure.

Also removed old, very unsafe node.osoutput(). We're now integrating cleanly
with the IDF/newlib way of redirecting stdout.
Added necessary depends in Kconfig to ensure VFS support is enabled, as
otherwise you'd only get a mysterious crash when attempting to enable
output redirection.
The IDF-provided VFS resolves several issues:
- The IDF components having a different view of the (virtual) file system
compared to the Lua environment.
- RTOS task/thread safety. Our legacy VFS was only ever safe to use
from the LVM thread, which limited its usability. Upgrading it
would have effectively required a reimplementation of the IDF VFS,
which would have been a bigger task with larger on-going maintenance
issues.
- We're no longer needing to maintain our own SPIFFS component.
- We're no longer needing to maintain our own FATFS component.
- The legacy of the 8266's lack of standard C interface to the file system
is no longer holding us back, meaning that we can use the standard
Lua `io` module rather than the cobbled-together swiss army knife
also known as the file module.
Of course, the downside is that we'll either have to declare a backwards
breakage in regard to the file module, or provide a Lua shim for the old
functions, where applicable.
Also included is some necessary integer type fixups in unrelated code,
which apparently had depended on some non-standard types in either the
SPIFFS or FATFS headers.
A memory leak issue in the sdmmc module was also found and fixed while
said module got switched over to the Espressif VFS.
Module documentation has been updated to match the new reality (and I
discovered in some places it wasn't even matching the old reality).
Search-and-replace considered harmful. I completely missed the need to
explicitly declare "fast" tag functions (__xyz) in the mask field to
LROT_BEGIN()/LROT_END() when I brought over the 5.1+5.3 support.
Without those flags set properly, the LVM doesn't even bother going
looking for those methods, which in this case led to garbage collection
not calling the __gc functions, among other horrible things.
Mea culpa.
