Damien George 67fd58bbd2 stm32/mboot: Add support for littlefs.
Mboot now supports FAT, LFS1 and LFS2 filesystems, to load firmware from.
The filesystem needed by the board must be explicitly enabled by the
configuration variables MBOOT_VFS_FAT, MBOOT_VFS_LFS1 and MBOOT_VFS_LFS2.
Boards that previously used FAT implicitly (with MBOOT_FSLOAD enabled) must
now add the following config to mpconfigboard.h:

    #define MBOOT_VFS_FAT (1)

Damien George 390f32922d stm32/mboot: Decouple stream, filesystem and top-level loading code.
This commit factors the code for files and streaming to separate source
files (vfs_fat.c and gzstream.c respectively) and introduces an abstract
gzstream interface to make it easier to plug in different filesystems.

Damien George 763bd448a4 stm32/mboot: Don't search for firmware on FS, just attempt to open it.
There's no need to do a directory listing to search for the given firmware
filename, it just takes extra time and code size.  Instead this commit
changes it so that the requested firmware file is opened immediately and
will abort if the file couldn't be opened.  This also allows to specify
files in a directory.

Damien George 3d0c31e60e stm32/mboot: Move some BSS vars to new section that isn't zeroed out.
Zeroing out data on startup takes time and is not necessary for certain
variables.  So provide a declaration for such variables and use it.

Damien George ff04b78ffd stm32/mboot: Add support for loading gzip'd firmware from a filesystem.
This adds support to mboot to load and program application firmware from
a .dfu.gz file on the board's filesystem.  See mboot/README.md for details.
