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).

The uzlib and parts of Lua had to be switched over to use the C standard int types, as their custom typedefs conflicted with RISC-V toolchain provided typedefs. UART console driver updated to do less direct register meddling and use the IDF uart driver interface for setup. Still using our own ISR rather than the default driver ISR. Down the line we might want to investigate whether the IDF ISR would be a better fit. Lua C modules have been split into common and ESP32/ESP32-S specific ones. In the future there might also be ESP32-C3 specific modules, which would go into components/modules-esp32c3 at that point. Our old automatic fixup of flash size has been discarded as it interferes with the checksumming done by the ROM loader and results in unbootable systems. The IDF has already taken on this work via the ESPTOOL_FLASHSIZE_DETECT option, which handles this situation properly.
