- implement file.size for spiffs (#1516)
- fix vfs_lseek() result checking in enduser_setup and clarify SPIFFS_lseek() return value (#1570)
- Handle error condition in file.read() (#1599)
* #2521: Add object-based file API to dev-esp32 branch
Merged in from master@c708828bbe853764b9de58fb8113a70f5a24002d minus
some VFS changes and similar.
* Updated file docs from master
Omitting:
* file.mount()
* reference to rtctime.epoch2cal()
* file.stat()
As these are not available in dev-esp32 branch
Unsure about whether "directories are not supported" is still true
* Set stdout to unbuffered
This fixes issue #2507 esp32 serial console doesn't show output until
enter pressed.
* Moved setvbuf call to app_main immediately after console_init
