d18157e108 vfs_fat: allocate FIL structures on the heap in vfs_fat_link
vfs_fat_link opened two files to perform copy operation. File structures
were allocated on the stack. When _MAX_SS setting was increased in
ffconf.h due to wear levelling feature, the size of these structures
increased to ~4k each (~8k total). This exceeds stack size allocated for
tasks in most typical cases.

This change makes file structures dynamically allocated.

1a73b41b10 vfs_fat: fix prepend_drive_to_path
Originally, prepend_drive_to_path was designed to be a macro, and it
modified local path variables to point to a temporary buffers.
When it was converted into a function, modification to path variables
were no longer visible outside of this function.

In addition to that, prepend_drive_to_path allocated 2k bytes on the
stack for temporary path buffers. This is replaced with path buffers
allocated as part of vfs_fat context object. Locking is added around
parts of code which use these temporary buffers.

Additionally, _lock member of vfs_fat_ctx_t was placed after the
variable-sized files array, which caused the first entry in the
array to be never used. This change fixes the order of members
and adds comments.

b540322dc1 Merge branch 'feature/wear_levelling' into 'master'
wear levelling

This MR adds wear levelling component. It presents an interface similar to the interface of spi_flash and esp_partition. Inside, it stores data inside a partition to in a way that reduces worst case number of erase cycles for any given sector.

Also included are APIs similar to the ones provided for SDMMC to mount FAT filesystem on top of the wear levelling partition. A simple example shows how this API can be used.

Ref TW10338.

8f02730e1f fat/sdmmc: unmount FATFS object on error
Failure to call f_mount(NULL,...) makes FATFS attempt to clean up the old
FS object upon next mount. If previous mount operation has failed, some
parts of FS object may not be fully initialized, which will cause errors
(such as attempting to delete a mutex which wasn’t allocated).

4ecd26ce77 Merge branch 'feature/fatfs_dynamic_pdrv' into 'master'
FATFS enable support for multiple drives

Current implementation has drive numbers and paths hardcoded to support
only one FATFS drive. Arduino has it's own SPI driver to allow
compatibility and flexibility. With the MR it is possible to have up to
```_VOLUMES``` drives connected (SPI, SDMMC and others) at the same
time and accessed through VFS

c17e05040a vfs_fat_sdmmc: if card init fails, fail cleanly
This fixes the issue with sdmmc_host not returned to clean state after
a failed attempt to mount the card, with no SD card in the slot.
