[Buildroot] [PATCH 0 of 5 v3] Introduce new deprecation symbols, and remove squashfs3/ttcp

[Thomas De Schampheleire]

In this third version I have stopped using the feature-removal-schedule.txt
file, and moved to an alternate strategy: introduce symbols
BR2_DEPRECATED_SINCE_xxxx_xx, which also provide an indication of when
features can be removed.

[Buildroot] [PATCH 1 of 5 v3] deprecated handling: introduce BR2_DEPRECATED_SINCE_xxxx_xx

[Thomas De Schampheleire]

In order to keep better track of when a feature got deprecated, and hence
when it can be removed, a new set of symbols BR2_DEPRECATED_SINCE_xxxx_xx is
introduced. These symbols are automatically selected when BR2_DEPRECATED is
selected, and thus are transparent to the user.
A deprecated feature will no longer depend on BR2_DEPRECATED directly, but
rather on the appropriate BR2_DEPRECATED_SINCE_xxxx_xx. If that symbol does
not yet exist, it has to be created in Config.in.
When removing a deprecated feature, one should also check whether this was
the last feature using the BR2_DEPRECATED_SINCE_xxxx_xx symbol, in which
case the latter can be removed from Config.in.

A followup patch will make sure the overview is added to the list of
deprecated features in the manual, so that a buildroot core developer can
easily determine which features to remove in a given development cycle.

[Buildroot] [PATCH 3 of 5 v3] manual package list: add symbol name in table

[Thomas De Schampheleire]

Particularly in the list of deprecated packages, it is not always clear what
the entry name refers to. For example, for squashfs3 rootfs support, the
string is simply "3.x". Likewise for the flex target binary: "Install tool
in the target".

To clarify the entries, add the actual symbol name (BR2_xxx) in the table.

[Buildroot] [PATCH 4 of 5 v3] squashfs3: remove deprecated package/rootfs

[Thomas De Schampheleire]

Signed-off-by: Thomas De Schampheleire <thomas.de.schampheleire@gmail.com>

Note: I did not add a legacy entry for  BR2_TARGET_ROOTFS_SQUASHFS4 because
it's simply removed, its role now played by the parent
BR2_TARGET_ROOTFS_SQUASHFS. Therefore, I don't think we need legacy symbols
in this case, right?

Just a small note: this patch series does not yet really add this
overview to the manual, I now realize. The manual looks as before,
except that the name of the symbol itself got added. I will try to
make a followup patch that changes that, but I think it can be
independent of this series.

  I checked the PDF output, and the column with the symbol names 
overflows into the following column, rendering the whole thing unreadable.

  Since it's only the two entries that you mention that are confusing, 
and since the squashfs3 part will be removed in the next patch, I'd 
dispense of this completely and instead change the wording of the flex 
symbol.

  Regards,
  Arnout

  At first I was afraid of the complexity added by this patch, but it's 
actually not that bad. Therefore:

  This should have been part of the commit message...

  But I agree with the principle.
