This adds support for the verification of a mangement vlan.
When enabled, then the switch's CPU will not listen to any packets
that are not tagged with the respective VLAN tag.
On the command line this is enabled by setting:
> vlan <vlan> mgmt
Setting the vlan ID of the management VLAN to 0 or 1 disables
the mangement VLAN function.
This adds a command history, both for the CLI as well as for
commands sent by the web-interface. They are written to a ring buffer
in order to work safely with a relatively small amount of RAM
The buffer is used to read the current in-RAM configuration
from the switch by the web-interface. It could also be used
to implement cmd history via cursor up/down in the CLI.
The Makefile has the version number and generates a version.h which
has VERSION_SW define that looks like "v<VERSION>-g<GIT_SHORT_HASH>".
Software version shows at boot in the serial console.
And shown with command: `version`.
It can also be requested via `information.json`.

flash_read_bulk() is kind of a printf function. But did not work as well.
flash_read_bulk() was used in the http generation so this needed to be changed as well.
For the website we decided that we are going to use CSR(Client Side Rendering).
So every HTML and JS files are now static.
Variables are fetched via json calls and output is render on the client side.
Also usefull for the future when we want a REST like API.
execute_config() was also using flash_read_bulk().
This have been replaced with flash_read_bulk() and parsing the flash_buf buffer.
Fix several bugs found in the write-flash code during installer coding.
Move all flash functions into CODE0. This is required to share these
functions with the installer image (currently they are duplicated so
they are not within the CODE1 segment).
De-magics all Flash command codes based on the Winbond W25Q32JV
datasheet.
