Ivan Grokhotkov 033124be14 spiffs: make OBJ_META_LEN configurable, make mtime support optional
- SPIFFS_OBJ_META_LEN can be set in sdkconfig
- mtime support can be enabled in sdkconfig, if META_LENGTH is sufficient
- add test for mtime updates

Enable this to have an identifiable spiffs filesystem.
This will look for a magic in all sectors
to determine if this is a valid spiffs system
or not on mount point.
config SPIFFS_USE_MAGIC_LENGTH
bool "Enable SPIFFS Filesystem Length Magic"
default "y"
depends on SPIFFS_USE_MAGIC

If this option is enabled, the magic will also be dependent
on the length of the filesystem. For example, a filesystem
configured and formatted for 4 megabytes will not be accepted
for mounting with a configuration defining the filesystem as 2 megabytes.
config SPIFFS_META_LENGTH
int "Size of per-file metadata field"

This option sets the number of extra bytes stored in the file header.
These bytes can be used in an application-specific manner.
Set this to at least 4 bytes to enable support for saving file
modification time.

default "y"
depends on SPIFFS_META_LENGTH >= 4
help
If enabled, then the first 4 bytes of per-file metadata will be used
to store file modification time (mtime), accessible through
stat/fstat functions.
Modification time is updated when the file is opened.
